Noise and Vibration surveys

Noise and vibration surveys are the main elements for any type of acoustic assessment. They can be either manual or automated.

Noise Surveys

A manual noise survey will include a visit to a site and the undertaking of noise measurements of a specific noise source. This can be anything ranging from a road to a fixed plant unit installation or any other type of activity (e.g. live music, religious service). This approach will allow a more controlled and accurate depiction of the acoustic identity of the source which needs to be assessed.

An automated noise survey will involve the installation of one, or more noise monitors for a minimum of 24hrs. The acquired data will be used to assess the noise profile of an area, identify any specific noise sources and provide further statistical information on the acoustic scenario under investigation.

A bespoke noise control strategy will follow, after the analysis of the acquired noise data, allowing a flexible, yet targeted solution.

Noise sources can vary in nature, however typical scenarios would include:

  • Fixed mechanical plant installations
  • Live music in a concert, or festival
  • Entertainment, or licensed premises venues (clubs, pubs, restaurants)
  • Religious services in places of worship
  • Clay target shooting
  • Road traffic noise
  • Noise from motorsports.

Vibration Surveys

A vibration survey will provide all the necessary information on the vibration profile of any source (e.g. a railway line). All the data from the vibration survey will assist in defining any potential impact on a proposed development and assess any adverse effect on either the building's occupants or the building itself (structural, or cosmetic damage).

vibration surveys

The vibration survey can be manual, or automated. A manual vibration survey will allow the direct assessment of a specific vibration source, therefore allowing a more detailed understanding of its properties and a more bespoke approach to the specific vibration impact assessment scenario.

An automated vibration survey will entail the deployment of one, or more vibration monitors which will either be collected after a minimum of 24hrs, or they will be set-up in such a way so as to transfer vibration data in real-time, allowing a more dynamic approach.

A detailed vibration control strategy could then be provided in order to minimise the effects of vibration, taking on board all the constraints of the project.

Typical scenarios where a vibration survey would be undertaken are:

  • Sites for residential development adjacent to railway lines
  • Refurbishments of lower-ground floor apartments and control of Underground Train vibration
  • Industrial plant unit installations
  • Condition monitoring of high-precision machinery
