When is a Noise Impact Assessment needed?
Any operator or permit applicant must consider the potential noise and vibration impact of their site. Noise impact assessments are required at the permit application stage, when applying to vary a permit and to comply with specific permit conditions. The environment agency will consider that if noise is audible at surrounding domestic and non domestic receptors there will be a possibility of causing impact. Where noise is possible causing impact then the operator or applicants assessment must determine the level of impact and what is requried to prevent and minimise noise pollution.
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 closest receptors of 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. Nova Acoustics Ltd have years of experience aiding with all kinds of noise impact assessment and our work is always informed and undertaken to the latest Government legislation and guidance.
