Unwanted noise can intrude on many areas in life. Similarly, noise impact assessment is a broad term and can apply to a wide variety of sectors and services. Typically, noise impact assessments are requested by a planning permission or environmental health officer to ensure that your development is not adversely impacting on communal, residential or businesses that are situated nearby.


Over the years, we have worked with many different types of clients and gained experience in offering bespoke noise impact assessment solutions that are suited to both exacting standards and budgets.

What is a noise impact assessment?

As the name suggests, a noise impact assessment will try to predict the impact that noise from your development is likely to have on the surrounding area. There are many reasons that developments require a noise impact assessment. This could be anything from a business extending its hours of operation, to a new construction project in a city centre. In each of these examples, the client would need to know the likely impact that their project would have on the surrounding area.

Finding out the answer to this question in advance can save a lot of money, hassle and time in the long run.

What is involved in a noise impact assessment?

A good quality noise impact assessment will:

  • Determine the existing level of noise (i.e. the baseline noise) at the proposed development

  • Predict the level of impact that the new proposal will have on this existing noise climate.

The specific type of noise impact assessment methodology will vary depending on the type of noise source that is of interest. However, a quality noise impact assessment will essentially involve measuring the existing noise climate that is associated with your development, as well as assessing the impact that the new proposal is likely to have on this climate. There are many different types of noise that can potentially impact on the surrounding area, including railway, aircraft, road traffic and industrial noise.
