Indoor Air Quality Testing and the Construction Industry
In recent years, the importance of indoor air quality (IAQ) has gained significant attention, and for good reason. As we spend a substantial amount of time indoors, whether it be at home, work, or other indoor spaces, the quality of the air we breathe can have a profound impact on our health and well-being. This is particularly relevant to the construction industry, where IAQ testing plays a crucial role in ensuring safe and healthy environments for workers and occupants alike.

During the construction process, various materials, such as paints, adhesives, solvents, and building products, are used extensively. While these materials are essential for building construction and renovation, they can release harmful pollutants into the air, potentially causing health issues if not managed properly. Indoor Air Quality testing in the construction industry aims to identify and mitigate these risks, creating healthier and safer indoor environments.

So, what exactly is IAQ testing, and how does it relate to the construction industry? IAQ testing involves the assessment of indoor air to determine the presence of pollutants, including volatile organic compounds (VOCs), formaldehyde, particulate matter, mold, and other potential contaminants. It typically involves a combination of sampling, monitoring, and analysis to evaluate air quality parameters, such as temperature, humidity, carbon dioxide levels, and specific pollutants.

In the construction industry, IAQ testing serves multiple purposes:

1️⃣ Compliance with Regulations: Construction projects must adhere to building codes, regulations, and standards established by local, state, and federal authorities. Many jurisdictions now require IAQ assessments to ensure that new buildings or renovations meet minimum air quality requirements. By conducting IAQ testing, construction companies can demonstrate compliance and avoid potential legal and health-related issues.

2️⃣ Worker Safety: Construction workers are exposed to various hasardous substances and conditions on a daily basis. Poor IAQ can exacerbate these risks, leading to respiratory problems, allergies, headaches, fatigue, and other health concerns. Regular IAQ testing allows construction companies to identify and address potential hasards, implementing appropriate control measures to protect workers’ health and well-being.

3️⃣ Occupant Health and Comfort: Once a construction project is completed, buildings are occupied by individuals who expect a safe and healthy environment. Poor IAQ can contribute to “sick building syndrome,” where occupants experience symptoms like coughing, sneesing, eye irritation, and fatigue. IAQ testing during and after construction helps ensure that the building’s indoor environment meets acceptable standards, promoting the well-being and comfort of its occupants.

4️⃣ Reputation and Customer Satisfaction: In an increasingly environmentally conscious world, people are becoming more aware of the importance of IAQ and its impact on their health. Construction companies that prioritise IAQ testing demonstrate a commitment to the well-being of their workers and the future occupants of the buildings they construct. Such proactive measures not only enhance their reputation but also contribute to customer satisfaction and overall project success.

To effectively address IAQ concerns in the construction industry, it is crucial for companies to incorporate IAQ testing into their project planning and execution. This includes engaging IAQ professionals who can conduct comprehensive assessments, provide guidance on best practices, and assist in implementing appropriate ventilation systems and pollutant control measures.

5️⃣ Green Building Certifications: Many construction projects strive to achieve green building certifications like LEED (Leadership in Energy and Environmental Design) or WELL Building Standard. These certifications place a strong emphasis on IAQ and require comprehensive testing and monitoring throughout the construction process. By conducting IAQ testing, construction companies can meet the criteria for these certifications, enhancing the marketability and sustainability of their projects.

6️⃣ Building Performance Optimisation: IAQ testing is not limited to new construction. Existing buildings can also benefit from testing to identify and rectify potential IAQ issues. Construction companies involved in renovation and retrofitting projects can conduct IAQ assessments to improve the performance of older buildings, enhancing energy efficiency, occupant comfort, and overall air quality.

7️⃣ Preventing Mold and Moisture Issues: Construction sites are susceptible to moisture intrusion, which can lead to mold growth if left unaddressed. Mold not only affects IAQ but also poses a serious health risk to occupants. IAQ testing can help identify areas of moisture buildup, enabling construction companies to take preventive measures and ensure proper ventilation and drying techniques are in place, thereby mitigating the risk of mold formation.

8️⃣ Long-Term Cost Savings: Investing in IAQ testing during construction can yield long-term cost savings for building owners and occupants. By identifying and rectifying IAQ issues early on, construction companies can prevent costly remediation efforts down the line. Additionally, optimising ventilation systems and controlling pollutant sources can result in energy savings and reduced operational costs for building owners.

9️⃣ Collaboration with HVAC Professionals: Indoor air quality is intricately linked to heating, ventilation, and air conditioning (HVAC) systems. Collaboration between construction companies and HVAC professionals is essential to ensure proper design, installation, and maintenance of HVAC systems that promote good IAQ. By working together, construction companies can ensure that the building’s ventilation system meets industry standards and effectively removes contaminants from the indoor environment.

Indoor air quality testing is not merely an optional add-on in the construction industry but a vital component for creating safe, healthy, and sustainable indoor environments. By integrating IAQ testing into construction projects, companies can demonstrate their commitment to worker safety, occupant health, regulatory compliance, and environmental responsibility.

Ultimately, prioritising IAQ testing contributes to the overall success, reputation, and longevity of the construction industry in an era where indoor environmental quality is gaining increasing attention and significance.

Soundproofing & Sound Insulation Testing

Adequately soundproofing your project to ensure you pass your sound insulation testing and meet the requirements of Approved Document Part E, should not be seen as pain. Achieving good soundproofing between dwellings such as houses and flats is incredibly important for our cities.

Residents don’t want to hear their neighbours through a poorly soundproofed party wall or floor. Currently, poor Sound Insulation is an issue that plagues many types of developments. This is accentuated if you have a noise neighbour who may like to play loud music, drum kits or simply enjoy tap dancing on the floor above your poorly soundproofed property.

Sound Insulation Testing
Most home owners may not understand the importance of Sound Insulation Testing to show compliance with the Part E of Building Regulations. When developers undertake the acoustic design and construction to their projects, they should be aiming for more than just a marginal pass; it should be about trying to attain a sound insulation performance of 55dB for airborne sound and 52dB for impact sound.

If developers design their projects to attain the aforementioned sound insulation values, they will reap the benefits in the long run. If they rent the blocks, their clients renting the dwellings will be less likely to leave due to noise issues.  Another plus is they will not have to deal with noise complaints on a weekly basis which can be stressful for both the resident and the development team. 

Having undertaken hundreds of design reviews for architects, developers and builders we know the challenges behind soundproofing new and converted developments. However complicated the construction, we try to find a solution to improve the sound insulation and help you pass your sound insulation test.

Firstly we look at the four basic principles of soundproofing

Ensuring Adequate Mass

One of the key ways to improve the sound insulation of a party floor or wall is to ensure there is adequate mass, this can be done by using one of the high mass acoustic mineral wool products. Using sound board (15mm) will help to ensure your plasterboard lining/s have the optimum mass to pass. It is very difficult to achieve the requirements of Approved Document E when using standard 12.5mm plasterboard on your wall and/or ceilings. If extra linings such as plywood, OSB, and cement board are introduced it makes the walls heavy and a lot more rigid, meaning the vibrations will be reduced

Decoupling Materials

All too often, residents can hear their neighbours walking across the floor in the apartment above them. This is particularly noticeable in if the apartment above has a marble tile and/or or a hardwood finish. When the units have this type of finish, it is essential that the floor partition has an acoustically robust construction

There are many ways to reduce the sound of footfall noise from the flat above, the best way is to introduce is decoupling to the ceiling structure to make it separate from the floor joists.  This can be done incorporating a Resilient Bar System, A suspended MF Ceiling or Independent Ceiling and/or a Genie Clip System. All these systems should decouple the soundboard lining from the joists above.

To improve further on the above upgrade/s you can also add a good quality acoustic mineral wool between the joists, studwork or ceiling void.  This needs to be tightly fitted between the framework to ensure good material coverage ‘so it doesn’t have any gaps or voids. You can also upgrade party walls; by using the systems mentioned above, as it will help to reduce the intensity and spread of sound waves and vibration through the party wall and should help you pass your sound insulation test.

In our experience the best results are usually attained by constructing a twin wall consisting of two layers of studwork, with a high density acoustic mineral wool between each stud wall with two layers of soundboard either-side.

We offer a total acoustic package consisting of acoustic consultancy and sound insulation testing; with a practical and costs effective approach from start to finish.

Ensure an Air Tight Construction

You can greatly improve your sound insulation performance by the introduction of an air tight seal. If there is any air leakage paths, gaps or holes sound will find a way through. Inadequate air sealing is one of the most common reasons for Sound insulation Test Failures. Luckily, it’s also one of the easiest things to improve.

Introduce Damping to your Construction

If you introduce damping to your party wall and ceilings it can help to reduce the vibrations through the construction caused by sound waves. Previously we have advised clients to use Tecsound between the plasterboard layers to great effect.

Damping materials such as Tecsound can be applied almost all types of party wall and floor construction where two layers of plasterboard board are being installed. When combined with genie clips, this can be a quick and effective way to upgrade your acoustic construction on site.

ISO Standard 14644-1: 1999 has recently been updated to the 2015 version. It requires changes to sampling procedures and monitoring plans for cleanrooms and clean zones, all of which is outlined in the revised ISO 14644-1:2015 standard. Organisations will be required to redefine their validation sampling plans and data evaluation and will obviously affect the clean room testing reportage.

The updated ISO 14644-1:2015, specifies the classification of air cleanliness in terms of concentration of airborne particles in cleanrooms and clean zones and is the first significant revision since its original release in 1999.

The major change from ISO 14644-1:1999 publication is the adoption of a more consistent statistical approach to the selection and number of sampling locations; and thereafter the evaluation of the data collected. 

This new approach allows each location to be treated independently with at least a 95 % level of confidence that at least 90 % of the cleanroom or clean zone areas will comply with the maximum particle concentration limit for the target class of air cleanliness.

Cleanroom users will have to make changes to the cleanroom validation procedures to meet the requirements laid out in the latest version of ISO 14644-1:2015 and ISO 14644-2:2015.  It is possible that the revised standard will require cleanroom owners to make changes to their cleanroom to ensure they continue to achieve the required classification and remain compliant.

UKAS Accredited Sound Testing

The need to carry out sound insulation testing to assess and report the acoustic performance of dividing partitions between dwellings has become increasingly important in order to demonstrate that a building’s intended performance is achieved when constructed.

Poor design detailing and/or onsite construction can have a significant impact on the overall performance of building elements and the building as a whole. Post completion sound testing provides greater certainty that designed performances are actually being achieved in compliance with Approved Document E.

Pre-completion Sound Testing is now an integral part of supporting the completion certificate process throughout the UK and Ireland. In order to ensure that testing is undertaken within a robust regime which controls the reliability of test results, government guidance is in place which describes restrictions on those who should carry out sound testing and reportage.

Approved Document E states a set of sound tests should be carried out for every ten dwellings (houses, flats or rooms for residential purposes). However, if the development has several different construction types, you may need to carry out further tests for each type of construction.

For houses this usually means you are required to undertake 2 airborne wall sound tests (up to 10 houses) to the dividing walls. For flats you will be usually be required to undertake 2 airborne wall, 2 airborne floor and 2 impact floor tests (up to 10 Flats). When we undertake a fee proposal for clients, we always include a full testing schedule so it can be submitted to building control for their approval prior to the test date.  

One of the stipulations of Approved Document E is that the testing company needs to be UKAS accredited, this is covered under the Resistance to the passage of sound: Approved Document E [ADE] it goes on to state that “The person carrying out the building work should arrange for sound insulation testing to be carried out by a test body with appropriate third party accreditation” and is downloadable at: https://www.gov.uk/government/publications/resistance-to-sound-approved-document-e.

APT Sound Testing is UKAS accredited to carry out sound insulation testing and is laboratory and as a result our reports will be accepted by building control – here is a link to our UKAS Sound Testing Accreditation: https://www.ukas.com/wp-content/uploads/schedule_uploads/00002/4340Testing%20Multiple.pdf

Overview of Noise Assessments & APT Sound Testing

APT Sound Testing focuses on noise tests that help meet planning rules for different projects. With a lot of experience, we carry out noise surveys following BS8233 and BS4142 guidelines. We handle noise problems for both homes and industries. If you are planning new homes like apartments or hotels or if you need to look at industrial noise from machines on old sites, our team offers careful checks that fit your needs.

Here, we’ll explain each kind of noise survey and what it does. This will help you decide which option might be right for your project.

BS8233 Noise Survey for Residential Developments

A BS8233 noise survey is usually needed for new homes, like apartments, houses, or hotels. These surveys look at how outside noise can impact future residents. They help local authorities understand the noise around the area and suggest ways to reduce it. These surveys are often asked for during the planning stage. BS8233 noise assessments help predict how noise from traffic, entertainment, or nearby industries might influence a new residential site.

In the UK, the National Planning Policy Framework says that new homes must offer a good level of sound comfort. This rule helps keep noise away from people. It includes things like soundproofing walls and putting up barriers outside. The goal is to keep both the inside of homes and outdoor places, like gardens, peaceful.

APT Sound Testing has completed many BS8233 noise assessments for different residential projects, including single homes and large apartment buildings. We team up with planning consultants, architects, builders, and private clients to make affordable noise solutions during the design phase. By spotting noise problems early, we help add noise reduction measures into the design. This prevents expensive fixes later and reduces noise impact on future residents.

In these surveys, our team checks noise levels to make sure they are okay. This often means taking readings at different times of the day, looking at noise both inside and outside the building. We then create recommendations for the project, focusing on certain noise sources. This could include using soundproof materials in the building or noise barriers around outdoor areas. Our aim is to make sure the development meets local rules while keeping a comfy space for people living there.

For clients who need a BS8233 noise survey, our team is here to talk about the details. We can show you how our checks can help your planning application go smoothly. Contact us at 01525 303905 or email us at info@aptsoundtesting.co.uk for more details.

BS4142 Noise Survey for Industrial Sites

BS4142 noise surveys are important for measuring noise from industries in places where homes and factories are close together. These surveys are often needed when new loud machines are added to a site. They are also necessary when noise from industries might bother nearby houses or other quiet places. As the government supports development on old industrial land, finding a balance between industry work and people’s comfort at home is more important than ever.

Noise from factories can greatly affect nearby areas. Because of this, local planners often set strict rules on how much noise can be made. It is important for machines and equipment to keep noise within allowed levels, especially at the edges next to homes. Our BS4142 surveys aim to measure how much noise these industrial sources make. We check if the noise levels meet the rules set by authorities.

To do a BS4142 noise assessment, we check the normal noise levels in the area. We do this with and without the noise source running, usually over 24 hours. This method helps us see how much the industrial noise affects the area and if it goes over local noise limits. Our skilled consultants use LA90, which is an important way to measure background sound. This shows the noise level that is too loud for 90% of the time we measure it. This helps us understand the noise in the area well.

Once we finish our measurements, we write a detailed report. This report includes noise maps to show how well we can reduce noise. If noise reduction is needed, we can suggest ways to lower the noise. This can include sound barriers, covering machines, or changes to buildings to keep noise inside. Our BS4142 checks look at different sources of industrial noise. This includes systems that take air out, air conditioning units, refrigeration tools, and regular noise from factories.

With a complete noise check, we help developers meet local rules. This makes sure that the project follows noise plans. If you have asked for a BS4142 noise survey, we can help you understand the process and the steps you need to take. Reach out to us today at 01525 303905 or email us at info@aptsoundtesting.co.uk to set up your assessment.

Noise Survey Planning for Development Applications

APT Sound Testing offers extensive expertise in conducting noise survey planning assessments for various development projects, addressing both residential and industrial noise issues to ensure compliance with local planning regulations. Our acoustic services include the BS8233 Noise Assessment for reducing noise in residential buildings and the BS4142 Industrial Noise Survey, assessing industrial noise impacts. These assessments play a crucial role in securing planning approvals by ensuring that proposed developments adhere to noise management standards.

BS8233 Noise Survey for Residential Developments

Noise assessments, such as the BS8233 survey, are commonly required for new residential developments, including apartments, houses, and hotels. Local authorities often impose noise-related planning conditions to evaluate potential noise impacts from a proposed project, especially for high-traffic areas or urban developments.

Residential buildings can be affected by various noise sources, such as traffic, industrial operations, and entertainment venues. The BS8233 noise survey seeks to address these potential disruptions by providing detailed analyses on noise levels within residential developments. Our team has performed hundreds of successful noise assessments for residential projects, helping planning consultants, architects, developers, and private clients implement cost-effective acoustic solutions at the design stage. Projects we support vary widely, from small residential buildings to large apartment complexes.

A BS8233 survey becomes essential when seeking full planning permission for residential projects. The survey includes a comprehensive acoustic assessment and noise survey of the development site. This step ensures the property will offer acceptable noise levels and create a healthy living environment for residents. This process aligns with the National Planning Policy Framework (NPPF) in England and Wales, which mandates suitable acoustic conditions for new residential developments. The goal is to establish appropriate noise barriers, such as sound-insulating building envelopes or external noise reduction measures like acoustic fences, to protect both interior and exterior spaces within residential zones.

For further details, our BS8233 Noise Surveys page provides additional insights into these services.

BS4142 Noise Survey for Industrial and Commercial Projects

If an industrial or commercial development involves introducing new noise sources or requires assessing existing industrial noise, a BS4142 noise survey may be required by planning authorities. Industrial noise assessments are increasingly necessary as residential and industrial sites grow closer, especially with the push for redeveloping brownfield areas. With expanding urban growth, residential buildings are often developed adjacent to industrial zones, raising concerns about noise impact on residents’ quality of life and general amenity.

Planning authorities often regulate noise emissions through planning conditions, which can involve restrictions on industrial noise levels and operating hours. Ensuring compliance with these requirements might involve insulating machinery or plant installations to maintain acceptable sound levels at property boundaries or nearby residences. A thorough BS4142 noise assessment outlines the noise levels allowed at the development site and details the measures needed to comply with these standards.

For a BS4142 survey, we measure current sound levels over a 24-hour period to establish a baseline and then evaluate potential new noise impacts by simulating the introduction of planned noise sources. In cases where new noise sources already exist, we measure ambient sound levels both with and without the noise source active to determine its impact. This process uses the LA90 metric, which captures the background sound level that is exceeded 90% of the time during the assessment period.

Our specialist team have extensive knowledge of BS4142 requirements, making them well-suited to perform accurate and comprehensive assessments.

APT Sound Testing’s BS4142 noise assessment report includes a detailed summary of findings and suggested mitigation measures where needed. Our team can provide noise mapping to illustrate how these measures impact the development’s noise environment. The report’s recommendations cover a range of potential noise sources, such as HVAC systems, industrial machinery, refrigeration equipment, and the general operation of industrial facilities.

For clients required to undergo a BS4142 Noise Assessment, we encourage direct contact at 01525 303905 or via email at info@aptsoundtesting.co.uk. More information on these services is available on our BS4142 Noise Survey page.

The Importance of Noise Surveys in Urban Development

Both BS8233 and BS4142 noise surveys are integral to urban planning and development. These assessments ensure that developments meet the dual objectives of supporting growth while safeguarding the welfare and comfort of residents. By addressing noise issues at the planning stage, developers can implement suitable design and acoustic measures, avoiding potential future conflicts with local authorities or resident complaints.

Noise surveys are particularly important in today’s urban landscape, where mixed-use developments are on the rise, and housing, retail, and industrial functions often occupy neighboring areas. Proper planning can prevent sound pollution from becoming a persistent issue and promote harmonious coexistence between various land uses. With the National Planning Policy Framework advocating sustainable and resilient communities, noise management is more relevant than ever in the construction and planning sectors.

APT Sound Testing is committed to supporting clients through every stage of their development projects, from initial noise assessment to the implementation of acoustic solutions. Our experience with both BS8233 and BS4142 noise assessments ensures our clients can confidently meet regulatory requirements and maintain the highest standards of noise management across residential and industrial developments alike.

Ensuring Compliance with BS4142 and Planning Conditions

If your project has received a planning condition that mandates a plant noise survey in accordance with BS4142, APT Sound Testing is here to assist. Our expertise in industrial noise surveys and sound testing can help you navigate the growing complexities of noise-related planning requirements, ensuring compliance and maintaining the quality of life for nearby communities.

As industrial sites are often situated close to residential areas, noise from industrial operations has become a significant concern for planning authorities. This is especially true as the UK Government continues to encourage the redevelopment of brownfield sites, which often places industrial operations and housing developments in close proximity. Noise levels and operational hours in these mixed-use zones can significantly affect the surrounding area’s amenity and quality of life. Therefore, effective noise control and management are essential components of planning approval.

The Role of Noise Control in Planning Approval

When planning authorities impose conditions related to noise emissions, controlling the noise output from plant and machinery becomes critical. By mitigating noise emissions, especially at the site boundary or near sensitive receptors such as homes, schools, or hospitals, developers can ensure that sound pressure levels stay within acceptable limits.

Establishing baseline noise levels and implementing proper mitigation measures helps protect nearby communities from the adverse effects of industrial noise. APT Sound Testing is experienced in conducting BS4142 noise assessments, offering full guidance and services to ensure your development complies with noise-related planning conditions.

What is a BS4142 Noise Assessment?

BS4142 is the British Standard that provides a method for assessing noise from industrial and commercial sources in environments that include residential properties. The main objective of BS4142 is to assess how industrial noise impacts nearby areas, particularly where people live. It compares the industrial noise level to the existing background noise level, identifying potential disturbances and helping to shape mitigation strategies to reduce adverse effects.

The process begins by measuring the existing background noise level (LA90), which is the level of noise that is exceeded for 90% of the time in a given period. This is typically done over 24 hours or at multiple times throughout the day to capture a complete picture of noise variations. The LA90 measurement provides a stable indicator of the background noise in the absence of the noise source being assessed. Once the background noise has been established, the sound from the industrial source is added, and the difference between the two is calculated to determine the noise impact.

Our team of highly trained and experienced consultants are well-versed in the methodology and requirements of BS4142. We ensure that each noise assessment is accurate, comprehensive, and tailored to your specific project needs.

Noise Monitoring and Impact Predictions

When introducing a new industrial noise source, such as machinery or air-conditioning systems, it is critical to evaluate its potential impact on the surrounding environment. APT Sound Testing can conduct noise surveys that involve continuous monitoring of sound levels over a 24-hour period. This gives us an accurate understanding of the existing ambient noise in the area.

Once the baseline measurements have been obtained, we predict the likely noise impact of the new source. If the noise source already exists, we measure the noise levels without the source and then again with the source operational. This allows us to determine the specific contribution of the new industrial noise to the overall environment.

Comprehensive Noise Survey Reports

Upon completing a noise survey, we provide a detailed report that outlines our findings. This report includes a full analysis of the noise data, identifying any areas where the noise exceeds acceptable limits and providing recommendations for mitigating these issues. Where necessary, we use noise mapping techniques to visually demonstrate the effectiveness of potential noise control measures.

Noise mapping is a highly effective tool for identifying areas of concern and evaluating the ‘real-life’ impact of proposed noise reduction strategies. By using this approach, we can recommend targeted mitigation measures, such as acoustic barriers, enclosures, or alterations to operational practices that will help bring noise levels in line with planning conditions.

Our noise assessments and surveys cover a wide range of industrial noise sources, including:

• Air-conditioning units
• Refrigeration systems
• Extraction systems
• General plant machinery
• Factory operations
• Warehouses

Pre and post Construction Sound Testing

The pre and post Construction sound testing of floors is an important part of ensuring that buildings meet the required sound insulation standards for Building Regulations Part E and/or the sound insulation requirements set out in your lease conditions. Here’s a brief overview for both:

Pre-Construction Sound Testing Overview:

Purpose of the pre-works sound test: To establish the existing sound insulation performance of the floor partitions between you and your neighbour. 

Sound testing process: the pre-works sound test is conducted before any construction work begins. It involves measuring the sound insulation levels of the floor partition to understand the baseline performance.

Importance of preconstruction sound testing: it helps in designing the necessary soundproofing measures to pass the sound test and/or improve the acoustic performance of the floor and ensure compliance with building regulations where required. It’s worth noting that we also offer an acoustic design service for party floors were required. 

Post-Construction Sound Testing

Purpose of the post works sound test: To verify that the soundproofing measures implemented during construction have achieved the desired sound reduction for Building Regulations Part E

Sound testing process: the second test visit is conducted after the construction is completed, but before the building is occupied. It involves similar sound insulation measurements to those done pre-construction.

Importance of post construction sound testing: Ensures that the building meets the required sound insulation standards pf Part E and/or the lease conditions of the block. It also identifies if the new floor construction is as good/better than the existing floor construction.

Preconstruction sound testing methodology

The preconstruction sound testing methodology involves several steps to ensure accurate results. Here’s a general guide sound testing steps:

Planning the preconstruction sound test: Schedule the test before any construction work begins. Ensure the area is accessible and free from obstructions. Always make sure doors and windows are installed on the day of the test.

Hire a qualified sound testing company: employ the services of a sound testing company accredited by a recognised body, such as the UKAS – the United Kingdom Accreditation Service. It’s worth noting that we are UKAS accredited to undertake sound testing.

Equipment Setup: The sound test engineer, will set up equipment, including sound sources and receivers, on both sides of the floor partitions, i.e. in your apartment and your neighbour/s below. We also require full access into the neighbouring property below and/or above.

Undertake both Airborne and Impact Tests: always conduct both airborne sound tests (measuring sound transmission through the air i.e. TV, Radio and Speech) and impact sound tests (measuring sound from footsteps or dropped objects) wherever possible. These are the two types of tests required under Building Regulations Part E.

Acoustic data Collection and comparison: the sound test engineers will measure sound levels and compare them against the required standards of Building Regulations Part E. 

Post construction sound testing methodology

Planning the post works sound testing: Schedule the test after construction is complete but before the building is occupied.

Hire a qualified sound tester: Ensure the tester has the correct accreditation such as UKAS etc. and follows the same standards as the pre-construction test.

Sound test equipment setup: Similar to pre-construction, the sound test engineers will set up equipment on both sides of the floor, so will need full access into both properties either side of the party floor.

Airborne and impact sound tests: Repeat the same tests as pre-construction to measure the sound insulation performance after construction works have been completed, so a direct comparison can be made between the acoustic performance of the old and new floor construction.

Acoustic data collection and reporting: The tester will collect data and provide a report detailing whether the sound insulation meets the required standards of Part E and/or the required lease conditions.

Acoustic Consulting Testing Services

Acoustic consulting and sound insulation testing are key for today’s building projects. This is very important for homes and places with different uses. At our company, we have a wide range of acoustic consulting services. APT Sound Testing can take care of sound insulation and noise problems to meet the rules set by Building Regulations Part E and planning needs. Our team includes skilled acoustic consultants who provide full solutions. We help from the design of the project to the final sound testing before it is finished. By offering expert help at every step, we assist developers in getting approval for the acoustic parts of their projects in a cost-effective way.

Sound insulation is important. It helps you follow rules, improves life quality, and increases property value. That’s why we offer a special way to test sound. We ensure your project meets legal standards and remains within your budget.

Sound Insulation Testing: Basic Measurements Setup

The first step in our sound consulting process is to test sound insulation. This means visiting the project site to see how well the walls and floors block sound, especially during changes or updates. These tests provide us with useful information on how well sound is stopped or absorbed by the existing walls between rooms or units.

During these site visits, we look at the walls, floors, and ceilings to see if they meet sound standards. If they do not, we make a design to fix the building’s problems. These changes ensure that your project will follow Building Regulations Part E. This part is about sound performance in new buildings and their changes.

Sample testing plays a key role in our design ideas. By checking how a building controls sound, we can find ways to improve it. This can happen without additional costs or delays.

Complete Sound Design Services: From Start to Finish

Acoustic consulting means more than just testing. It is about creating a full acoustic plan that includes the entire project. It starts with the design and goes all the way to the final soundproofing tests. Our services ensure that every part of your building’s sound performance is handled properly.

Our consultancy process includes:

1. Initial Site Survey Visits: We start by examining the building closely. This helps us find issues like light blocks or weak soundproofing. These early visits are important for spotting problems like poor sound blocking or low-quality insulation. We also check that the teams are using the manufacturer’s instructions when installing soundproofing materials.
2. Sample Sound Testing of Existing Construction: After the first visit, we conduct sound tests. This test shows how well the building stops sound. We review the results to create a specific sound plan based on the building’s condition. This ensures any changes fit the building’s needs, improving the cost and success of sound measures.
3. Acoustic Design Review: In this step, we closely examine the walls and floors of the building. This is important because it helps us ensure that the weight, separation, and soundproofing parts of the design are included. These three parts are vital for good sound blocking:
   • Mass: Heavier materials block sound better as they resist sound waves.
   • Isolation: This means keeping areas of the building separate to prevent sound from passing between them, like using channels or floating floors.
   • Absorption: Materials that soak up sound, such as insulation or sound panels, reduce noise traveling through walls, floors, and ceilings.
4. By reviewing these elements, we ensure the building meets Approved Document E and will pass the final sound test.
5. Pre-completion Sound Testing: The last step is pre-completion sound testing, necessary to prove that we follow Building Regulations Part E. This testing looks at both air sound and impact noise between rooms or units.
   • Airborne noise includes sounds that travel through air, like talking, music, or TV noise.
   • Impact noise comes from hitting surfaces, such as footsteps or moving furniture.
6. Pre-completion sound testing confirms that the building prevents sound from traveling properly, meeting the noise reduction rules.

Approved Document E: Guidelines for Achieving Sound Insulation Standards

Since July 2003, Part E of the Building Regulations says that all new buildings and changes must be checked for sound insulation. These rules help reduce noise between homes. This makes it feel more private and comfortable for people living there.

Part E says that we need to test at least 10% of all types of party walls or floors in a building. We generally conduct sound insulation tests between two rooms that share these walls or floors. This ensures that noise stays low.

Sound testing measures two types of noise:

1. Airborne noise: This is sound that travels through the air, such as talking, music, or the TV. Tests for airborne sound insulation check how well the building stops or reduces this noise.
2. Impact noise: This occurs when objects hit a building, like footsteps or moving furniture. Tests for impact sound insulation check how well the building lowers these sounds when they happen above or beside another room.

By doing both types of sound insulation tests, we can check if a building follows the rules in Part E. This helps to provide a good level of noise comfort for the people living there.
