Industrial noise surveys for planning applications

If you are applying for planning permission for a new industrial or commercial development, or installing new plant or machinery at your existing site, the local authority may request a noise assessment.

Industrial noise has the potential to cause adverse impacts on the local residents, businesses and the environment, and measures must be taken to ensure that noise does not exceed the required limits.

Our consultants have extensive experience in industrial noise. Our assessments are carried out in accordance with BS4142:2014 Methods for Rating and Assessing Industrial and Commercial Sound, as recommended by local authorities.

We have developed longstanding working relationships with Environmental Health Officer and Planning Departments and are happy to liaise with them on your behalf to address any potential noise issues at an early stage.

We are able to recommend a number of acoustic solutions to mitigate the impact of noise, if required.

We aim to give your application the best chance of approval, first time.

BS4142 noise assessments - what's involved?

BS4142:2014 is a British Standard that provides an approved method of assessing the impact of industrial or commercial noise. The standard supports current UK planning guidance and Environment Agency requirements on noise assessments.

Your industrial noise assessment will typically include:

  • A measurement of existing (baseline) noise at the site.
  • Assessment of noise impact for your proposed project or development.
  • Analysis of noise data using industry leading 3D modelling software.
  • A full technical noise impact assessment report.
  • Recommended mitigation measures, if necessary.

You’ll get a fast and professional response, wherever you are in the UK. Depending on your requirements, we will typically provide a full technical report within 10-14 working days of receiving your order. However we will endeavour to meet any deadlines where possible.

BS4142 The rating of industrial and commercial sound

When do I need an industrial noise assessment?

Some examples where a BS4142 noise survey is typically required:

  • A proposed industrial or commercial development near existing residential units
  • New or existing plant and machinery
  • Chiller, air-conditioning and condenser noise breakout
  • Commercial and industrial ventilation noise breakout
  • Noise breakout from fans, extraction systems and generators
  • Assessment of existing industrial and commercial sites and advising on noise control
  • In response to complaints from local residents
  • Loading and unloading operations in factories, warehouses, depots and industrial facilities

The specifications below are widely used with reference to a noise impact assessment.

Concerned about noise within the workplace?

Industrial noise can also be a concern within the workplace for employees. In line with The Control of Noise at Work Regulations (2005), employers are obliged to comply with Noise at Work regulations and a noise risk assessment should be carried out.

Industrial noise from plant and industrial operations often requires professional advice on noise control to lower noise levels to ensure a safe working environment and HSE compliance. This can have the added benefit of reducing noise levels for nearby residents and businesses.

Our consultants have extensive experience in carrying out noise at work surveys and will ensure that your company is compliant with relevant noise at work standards.

    Case Studies


    Industrial noise impact assessment (BS4142) - Lancashire

    NoiseAir were instructed to carry out a BS4142 noise assessment at a specialist joinery and manufacturing company in Darwen, Blackburn. Concerns had been raised by nearby neighbours that excessive noise was being created from a large dust extraction unit on the exterior of the building.

    The noise assessment was carried out in accordance with BS4142 guidance, which is used to assess the impact of industrial sound. As expected, the noise survey confirmed excessive noise levels at the nearest houses.

    Using specialist software, our consultants were able to accurately calculate the noise reduction level, with various mitigation options. A full acoustic enclosure was not viable, however we were able to provide a solution via acoustic quilting panels. The acoustic panels offered satisfactory noise reduction within the company's budget.
