BS 8233 Noise Surveys & Assessments
BS 8233 Noise Surveys & Assessments for Planning Applications
If you are planning a new residential development, care home, student accommodation, hotel or mixed-use scheme, your Local Planning Authority (LPA) may require a noise assessment to demonstrate that future occupants will be adequately protected from environmental noise.
A BS 8233 Noise Assessment can help establish whether suitable internal and external noise conditions can be achieved and, where necessary, identify appropriate acoustic mitigation measures.
At APT Sound Testing, we undertake BS 8233 noise surveys and assessments throughout the UK, helping developers, architects, planning consultants and landowners meet planning requirements and create comfortable acoustic environments for future occupants.
What Is a BS 8233 Noise Assessment?
BS 8233:2014 – Guidance on sound insulation and noise reduction for buildings provides recommendations for acoustic conditions within residential and other noise-sensitive buildings.
A BS 8233 assessment considers existing and, where relevant, proposed noise sources around a development. These may include:
- Road traffic
- Railways
- Aircraft
- Commercial and industrial activities
- Mechanical plant and building services
- Pubs, restaurants and entertainment venues
- Distribution centres and service yards
- Other environmental noise sources
The assessment considers whether appropriate internal noise levels can be achieved within noise-sensitive rooms, such as bedrooms and living areas.
It may also consider external amenity areas, including gardens, balconies, roof terraces and communal spaces, where these form part of the development.
Why Is a BS 8233 Assessment Required?
A Local Planning Authority may request a noise assessment where a proposed development is located close to significant sources of environmental noise.
Typical examples include developments close to:
- Main roads and motorways
- Railway lines and stations
- Industrial estates
- Commercial premises
- Distribution and logistics centres
- Public houses and restaurants
- Entertainment venues
- Airports and flight paths
The purpose of the assessment is to demonstrate that noise has been appropriately considered as part of the development. It also shows that suitable acoustic measures can be incorporated into the building design where required.
A well-prepared assessment can also help planning officers and Environmental Health teams understand the site’s potential noise impact and the measures proposed to control it.

What Information Is Required for a BS 8233 Noise Assessment?
To prepare an accurate assessment, we normally require information about the site, proposed development and relevant planning requirements.
Providing as much information as possible at the outset can help us establish the scope of the assessment and provide an accurate quotation.
1. Site Address and Location Plans
We normally require:
- Full site address
- Site boundary plan
- Site location plan
- Planning application reference, where available
This information allows us to identify the development location, surrounding land uses and potential noise sources, as well as determine suitable positions for environmental noise monitoring.
2. Architectural Drawings
Where available, please provide:
- Proposed site layout
- Floor plans
- Elevation drawings
- Building sections
- Roof plans, where applicable
The drawings help us identify noise-sensitive rooms and determine which façades are likely most exposed to external noise.
PDF drawings are normally suitable, although DWG files can also be useful where detailed acoustic design information is required.
3. Details of Noise-Sensitive Rooms
The assessment may need to consider the internal rooms most affected by external noise.
These can include:
Bedrooms
- Main bedrooms
- Secondary bedrooms
- Guest bedrooms
Living Areas
- Living rooms
- Open-plan kitchen and living areas
- Dining areas
Other Habitable Rooms
- Home offices
- Studies
- Lounges
The location and use of these rooms can influence the acoustic performance required from the building envelope, including glazing and ventilation systems.
4. External Amenity Areas
Where applicable, external amenity areas may also nrequire consideration
Please provide details of:
- Private gardens
- Balconies
- Roof terraces
- Shared courtyards
- Communal gardens
- Other external amenity spaces
We can assess the likely acoustic conditions within these areas and advise on appropriate mitigation where required.
5. Planning Conditions and Environmental Health Comments
Planning documents and correspondence from the Local Authority can be particularly useful when determining the scope of a noise assessment.
Where available, please provide:
- Planning decision notices
- Noise-related planning conditions
- Local Authority consultation responses
- Environmental Health comments
- Requests for further acoustic information
These documents help ensure the assessment addresses the planning authority’s specific requirements.

6. Proposed Building Construction
Where available, we also require information about the proposed building envelope and construction.
This may include:
Glazing
- Double glazing
- Triple glazing
- Acoustic glazing
- Proposed glazing specifications
Ventilation
- Openable windows
- Trickle ventilators
- Mechanical ventilation
- Mechanical ventilation with heat recovery (MVHR)
External Walls
- Masonry construction
- Timber frame
- Lightweight façade systems
- Other proposed wall constructions
This information helps determine whether the proposed building specification can achieve the required internal acoustic conditions.
Where necessary, APT Sound Testing can also provide advice on building acoustic design and suitable mitigation measures.
7. Existing and Proposed Noise Sources
Information about existing and proposed noise sources can also assist the assessment.
Examples include:
- Industrial activities
- Commercial premises
- Existing plant and machinery
- Service yards
- Loading bays
- Delivery areas
- Public houses and restaurants
- Entertainment venues
- Proposed mechanical services plant
Where new or existing commercial or industrial plant is a significant noise source, a separate assessment under BS 4142 may also be appropriate.

8. Access for Environmental Noise Monitoring
Depending on the site and planning requirements, you may need an attended or unattended environmental noise survey.
To arrange monitoring, we may need:
- Site access details
- A site contact
- Information about suitable monitoring locations
- Security arrangements where monitoring equipment is left unattended
APT Sound Testing can advise on suitable monitoring positions to help ensure the measurements represent the site’s acoustic environment.
What Happens After We Receive the Information?
Once you provide the required information, our acoustic consultants will review the proposed development and determine the appropriate assessment methodology.
Depending on the project, the process may include:
- Reviewing the proposed development and architectural drawings.
- Identifying existing and potential future noise sources.
- Carrying out environmental noise monitoring where required.
- Assessing the measured or predicted noise levels against relevant BS 8233 guidance.
- Assessing the proposed building envelope and acoustic design.
- Recommending mitigation measures where necessary.
- Preparing a comprehensive BS 8233 Noise Assessment Report for submission to the Local Planning Authority.
What Acoustic Mitigation Measures May Be Required?
Where external noise levels are significant, the assessment may identify the need for additional acoustic measures.
Depending on the development, these could include:
- Enhanced acoustic glazing
- Improved façade specifications
- Alternative ventilation strategies
- Acoustic trickle ventilators
- Mechanical ventilation or MVHR
- Acoustic barriers
- Revised building orientation
- Changes to room layouts
- Improvements to external building elements
The appropriate solution will depend on the site’s noise environment, proposed development and architectural design.
Early acoustic input can therefore be valuable, particularly where a site is exposed to significant road, rail, commercial or industrial noise.

When Should You Arrange a BS 8233 Assessment?
Ideally, address acoustic considerations as early as possible in the planning and design process.
An early assessment can help identify potential noise issues before the building design is finalised. This makes it easier to incorporate suitable glazing, ventilation, façade construction, and other mitigation measures without requiring significant changes later.
If the Local Planning Authority or Environmental Health Department has already requested an acoustic assessment, providing the relevant planning correspondence and drawings will help us establish exactly what information is required.
