BS4142:2014 Assessments

British Standard (BS) 4142:2014 describes how the measurement and assessment of industrial noise sources should normally be undertaken in the United Kingdom. It is widely used to assess noise from sources such as fixed plant, deliveries and manufacturing processes.

Planning Approvals for schemes introducing new noise sources to locations close to noise sensitive premises will often include a BS 4142 planning condition. The purpose of the resulting assessment is to determine the significance of the noise impact and, where necessary, limit the impact through the implementation of mitigation measures. Such mitigation measures might include reselection of plant, repositioning of noise sources, limiting times of use or specifying acoustic treatments.

NSL provides services covering the full scope of BS 4142 across the UK. This includes reference noise surveys, background noise surveys, assessment reports and mitigation advice.
