A noise survey report may be required for a variety of reasons. We offer expert acoustic surveys for all your needs including:
Vibration & Noise Surveys
Noise surveys can cover a specific area or range of areas to provide you with a complete understanding of the sound levels at nearby receptors and can be tailored to ensure they provide a complete and accurate record of noise and vibration levels.
We provide noise surveys and noise impact assessments for a wide range of projects to support planning applications.
Our acoustic engineers are able to provide noise surveys and noise impact assessments for almost any noise and vibration scenario. Our detailed knowledge of Local Authority requirements allows us to complete an acoustic survey and report for planning applications in London and around the UK within very short time frames.
A noise survey is generally required for planning purposes such as determining the exposure to noise of proposed residential sites or the proposal of new plant installations (air conditioning, kitchen extract fans etc.).
For most assessments, planning and design work begins with an acoustic survey of the existing environmental noise climate at a site. This provides a baseline level and determines the main noise sources that must be considered for the site.
Noise measurements are usually undertaken over several days and nights to understand variations in the acoustic environment and determine typical levels. These automated surveys involve the installation of one or more sound level meters in suitable external locations to log the incident sound levels. This data is then downloaded for statistical analysis and the noise measurements are summarised in a noise survey report.
Attended noise measurements may be required where a specific noise source must be observed while being measured, where a short duration measurement is sufficient or where the situation does not allow for unattended noise monitoring.
We would usually include a set of attended noise measurements when undertaking automated noise monitoring to sample the variation across the site and measure identified noise sources.
A vibration survey is undertaken where there is a risk that a nearby railway, tube line or industrial process may cause unacceptable levels of vibration in a new development.
Alternatively, a new infrastructure project may require pre-existing baseline vibration levels to be recorded to ensure that neighbours are not adversely affected.
Vibration levels are usually measured during a short term attended survey when the source in question is identified and predictable. Baseline surveys usually require unattended monitoring over several days by equipment installed at suitable locations.
Surveys of vibration levels are also undertaken in buildings to confirm that the building services equipment is correctly mounted and not generating re-radiated noise.
