BS 4142 Industrial or Commercial Noise Surveys
Local Authority Planning Applications or Environmental Permit Applications for commercial or industrial sites often require a Noise Impact Assessment or noise survey report following the guidance of British Standard 4142:2014 methods for rating and assessing industrial and commercial sound including fixed plant installations (e.g. air conditioning, kitchen extracts).
A noise assessment can be required when your project will introduce new noise sources to a location close to residential accommodation. The purpose of the resulting noise assessment report is to clearly determine if noise complaints are a likely result of the new noise source.
In some cases where the proposal will lead to noise complaints, we can specify cost effective mitigation to enable the scheme to proceed. Often by re-positioning or enclosing the noise source.
BS 8233 Residential Development Noise Surveys
During a Local Authority planning permission for a new or update to a residential development, it’s common that your Local Authority will request a noise impact assessment or noise survey if your proposed dwelling is near a noise source such as a busy road, railway line, industrial premises, or entertainment venue. These types of assessments are generally formed under the guidance within British Standard 8233:2014: Sound insulation and noise reduction for buildings and the Professional Planning Guidance (ProPG) 2017.
The recently published Acoustics Ventilation and Overheating (AVO) Residential Design Guide guidelines recommend an approach for “good acoustic design” as described in the ProPG. The AVO guide gives detailed guidance regarding the impact of noise ingress under overheating conditions.
Road traffic and rail noise is important for planning purposes for new build developments to make sure the internal noise levels are acceptable. There are recognised standards such as the Calculation of Road Traffic Noise (CRTN) and Department of Transport Technical Memorandum Calculation of Rail Noise, 1995 (CRN) which we work to. The noise monitoring procedure set out in CRTN requires that road traffic noise is monitored for a continuous period of three hours on a normal week-day between 10.00 hours and 17.00 hours at a location which is at least 3.5 metres from the nearest kerbside. The 3-hour road traffic noise level measured can then be converted to an 18-hour level.
The aim of a noise assessment is to quantify the baseline noise environment at the proposed site and surrounding area. The potential noise impact on the future occupants of the residential dwelling will be assessed. It is important that noise levels are controlled to an acceptable level both internally and externally, to provide comfortable living and sleeping conditions.
The process of undertaking a planning application noise assessment generally includes:
- Measure the existing noise environment at and around the proposed development.
- Calculation of internal noise levels of dwellings within the development.
- Compare the calculated internal noise level with Local Planning Policy and assess compliance.
- If necessary, provide Mitigation Advice to demonstrate that Local Planning Policy can be met.
To meet guideline noise levels, and if required, we can determine the type of double glazing and ventilation specifications you require based on the results of the noise survey.
Noise at Work Surveys
The Control of Noise at Work Regulations (CNAWR) places a duty on employers to make an assessment of noise exposure within their workplace and ensure that noise exposure levels are reduced to as low as reasonably practicable. In addition there is a specific requirement for those employees exposures to average noise levels exceeding 80dB to undergo an ongoing regime of health surveillance.
There is also an exposure limit value of 87 decibels, taking account of any reduction in exposure provided by hearing protection, above which workers must not be exposed.
The Noise at Work assessment is completed in three stages...
- Conduct an on-site Noise Survey and conduct a series of noise measurements across the working day to determine the level of noise exposure.
- Assess the noise exposure risks considering the personal noise doses of employees against the noise exposure action values and limits as set out by the Noise at Work Regulations 2005.
- Advise on noise mitigation actions such as hearing protection, train employees, and reduce noise levels at source by altering the working process.
Whether you require an L108 workplace noise survey report, health surveillance or just simply advice, you can be reassured our team will be able to help.
Construction Site Noise Monitoring
We have experience of operating at a number of construction sites, working alongside construction teams and local authorities to provide an agreed monitoring methodology, risk assessment and suitable acoustic solutions action levels within a wider Construction Environmental Management Plan (CEMP) in order to satisfy the noise requirements or planning conditions imposed upon the site.
Noise Management Plan
A Noise Management Plan (NMP) can be required to support an Environmental Permitting Application or a Planning Application. It has two main purposes: A statement of intent with regards to your intention to mange noise on site.
A NMP will normally include:
- Robust policies and procedures applied to the project.
- Fixed and mobile sound limiting and monitoring equipment.
- Training procedures for managers and other staff associated with the project.
- An on going review process
- A detailed complaints monitoring system.
FAQs
Q. Are you qualified to undertake the noise survey?
A. Yes, our team have the IOA environmental noise certificate and are active members.
Q. What equipment do you use?
A. We use Class 1 calibrated Sound Level Meters.
Q. How long does the noise assessment take?
A. Depending on what is required, normally 1 to 2 weeks, weather permitting if on site noise monitoring is required.
Q. What is included in the Noise Assessment?
A. A pdf report detailing the method, and results of any noise monitoring and acoustic solutions, if required..
