Noise and Acoustic Consultancy in London
Professional Noise and Acoustic Consultancy in London
Noise can have a significant impact on the way a building is designed, used and enjoyed. Whether you are planning a new residential development, dealing with a noise complaint, installing new plant or equipment, or simply trying to improve the sound insulation of an existing building, getting the right acoustic advice early can save considerable time, expense and disruption later on.
APT Sound Testing is an experienced professional noise and acoustic consultancy serving Greater London, the Home Counties and clients throughout the UK. Our qualified and experienced acoustic consultants provide practical advice and detailed assessments covering a wide range of noise and acoustic issues.
From BS 4142 noise assessments and London noise surveys to acoustic design and sound insulation testing, we help homeowners, developers, architects, contractors and businesses understand their acoustic requirements and find effective solutions.
London Noise Surveys and Acoustic Assessments
We carry out noise surveys for a wide variety of sites, including proposed residential developments and other noise-sensitive buildings. This can include locations affected by road traffic, railways, aircraft, commercial premises or industrial activity.
Our approach is straightforward: we establish the existing noise environment, assess how it could affect the proposed development and recommend suitable measures to control or reduce unwanted noise.
Depending on the project, our work can include:
- Noise surveys and noise assessments
- BS 4142 assessments
- Acoustic assessments for planning applications
- Noise impact assessments
- Environmental noise monitoring
- Noise mitigation proposals
- Assessment of noise from plant and equipment
- Acoustic design advice
- Sound insulation testing
- Advice on meeting Building Regulations Part E
Where new mechanical plant, ventilation equipment or other noise-generating equipment is proposed, we can also establish appropriate noise emission limits and advise on mitigation measures to help meet Local Authority requirements.
Local Knowledge Matters
Acoustic requirements can vary considerably between developments, particularly when planning policies and local environmental conditions are taken into account.
As a company working extensively across Greater London and the surrounding areas, APT Sound Testing has considerable experience of the requirements associated with London planning applications and noise-sensitive developments.
Our consultants have worked on projects involving residential, commercial and industrial properties, giving us a practical understanding of how noise can affect both developments and the surrounding community.
By considering potential acoustic issues at an early stage, problems can often be identified and resolved before they become expensive construction or planning issues.
Noise Surveys for New Developments in London
A noise survey may be required as part of the planning process for a new development, particularly where a site is close to busy roads, railway lines, airports, commercial premises or other significant noise sources.
In some cases, the Local Authority may request a noise assessment during pre-application discussions. A planning condition may also require a survey or acoustic report before construction can begin or before a development can be occupied.
Ideally, the noise survey should be carried out during the design stage. Understanding the existing noise levels at the site allows the acoustic performance of the proposed building to be considered from the outset.
For example, if external noise levels are relatively high, the building envelope may require enhanced acoustic performance. This could involve specifying suitable glazing, ventilation systems, wall constructions or other measures to ensure acceptable internal noise levels.
Depending on the planning requirements, further testing or assessment may also be required after construction to demonstrate that the required internal noise criteria have been achieved.
What Does a Noise Survey Report Include?
The exact contents of a noise survey will depend on the nature of the project and the requirements of the Local Authority. However, a comprehensive report will typically include:
- The purpose and scope of the assessment
- A location plan showing the proposed development and relevant noise-sensitive receptors, such as nearby residential windows
- Survey methodology, including monitoring locations, equipment used and weather conditions
- Details of any deviations from recognised standard methodologies and the reasons for them
- A full set of survey results
- Comparison of measured noise levels against the relevant standards and criteria
- Recommendations for noise mitigation, such as acoustic barriers or improved building elements
- Supporting calculations demonstrating the expected reduction in noise from the proposed mitigation measures
A good acoustic report should not simply present measurements. It should explain what those measurements mean for the proposed development and provide practical recommendations that can be incorporated into the design.
Noise Exposure Categories (NECs)
Noise Exposure Categories, or NECs, are used to help assess the impact of environmental noise on a proposed development.
The category applicable to a site helps determine how seriously noise needs to be considered as part of the planning process. Noise levels are normally established through appropriate monitoring, after which potential mitigation measures can be assessed.
Depending on the site, mitigation could include acoustic barriers, enhanced glazing, improved ventilation arrangements, changes to the building layout or other acoustic design measures.
Where possible, addressing these issues during the design stage is preferable to attempting to resolve them after construction has started.
A detailed and accurate acoustic assessment can therefore play an important role in preventing noise-related planning problems and ensuring that appropriate mitigation is incorporated into the development from the beginning.
Acoustic Design and Building Regulations Part E
Noise consultancy is not limited to external environmental noise. We also provide advice on the sound insulation performance of walls, floors and other building elements.
For residential developments, meeting the requirements of Approved Document E of the Building Regulations is an important part of the construction process.
Our acoustic consultants can provide advice on soundproofing design and help identify suitable construction details to achieve the required level of acoustic performance.
Our services include:
- Noise surveys to support planning applications
- Acoustic design services to help projects meet Building Regulations Part E
- Sample sound testing to assess the acoustic performance of existing construction
- Acoustic site inspections to identify potential construction issues
- Visual inspections to check that acoustic details are being installed correctly
- Pre-completion sound testing in accordance with Building Regulations Part E
By combining acoustic consultancy, site inspections and sound testing, we can provide a more complete picture of a building’s acoustic performance.
Pre-Completion Sound Testing in London
Pre-completion sound testing (PCT) is used to demonstrate compliance with the sound insulation requirements of Approved Document E of the Building Regulations.
Testing is generally carried out once the relevant walls, floors and other separating elements have been completed, but before the building is handed over or occupied.
The tests assess the acoustic performance of the completed construction and can identify whether the required standards have been achieved.
Carrying out testing at the appropriate stage of construction is important. If problems are discovered after a building has been completed and occupied, remedial acoustic work can be significantly more disruptive and expensive.
For developers and contractors, arranging sound testing as part of the construction programme helps ensure that any issues can be identified at the right time.
Acoustic Site Visits and Sample Sound Testing
Sometimes the best way to understand an acoustic problem is to inspect the building itself.
APT Sound Testing can undertake acoustic site visits to examine existing construction and identify areas that could affect sound insulation performance.
During a site visit, we can look for issues such as unsuitable construction materials, gaps or weaknesses in acoustic details, or installation problems that could compromise the intended performance of a wall or floor.
We can also carry out sample sound testing of existing construction. This provides useful information about the actual acoustic performance of existing partitions and separating elements.
Having this information allows us to develop more targeted acoustic improvements rather than relying solely on assumptions about how a particular construction should perform.
BS 8233 Noise Surveys in London
Noise assessments are frequently required during the planning process for developments that either generate noise or are particularly sensitive to noise.
This can include residential developments, schools, hotels, healthcare buildings and mixed-use schemes. In some cases, a development may both generate noise and be affected by noise from surrounding sources.
A noise assessment will generally establish the existing acoustic environment and consider how the proposed development could change it.
For developments that could generate significant noise, a Noise Impact Assessment may be required. This can involve measuring existing background and ambient noise levels and predicting the likely impact of the proposed development.
Larger projects may also need to consider secondary effects. For example, a development that increases traffic could potentially affect noise levels on surrounding roads.
Assessing Internal Noise Levels
For noise-sensitive developments, it is often important to understand how much external noise will be experienced inside the completed building.
Our consultants can use noise prediction and acoustic calculation methods to assess expected internal noise levels and determine whether additional measures are required.
The overall acoustic performance of a building envelope can depend heavily on the glazing, ventilation and construction systems used.
Where external noise levels are high, it may be necessary to specify particular glazing or ventilation systems to ensure that suitable internal noise criteria can be achieved without compromising ventilation or occupant comfort.
Considering these requirements during the design stage makes it much easier to incorporate appropriate acoustic measures into the building.
Practical Acoustic Advice from Experienced Consultants
Whether you are a property developer, architect, contractor, business owner or private individual, acoustic issues can sometimes appear complicated.
Our role is to make the process as straightforward as possible.
A typical noise assessment is not necessarily intrusive or time-consuming. Depending on the requirements of the project, we may install a noise meter at the site for a period such as 24 hours so that sufficient data can be collected.
The equipment can automatically record the relevant noise information while taking account of the site’s surroundings and external conditions.
Once the survey has been completed, our consultants can analyse the results, prepare a detailed report and explain what they mean for your project.
Most importantly, we can provide practical recommendations on what needs to happen next.
