Noise Survey

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

A manual noise survey will initially include a visit to a site and the undertaking of noise measurementsof a

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.

Similarly, 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 assets any adverse effect on either the building's occupants or the building itself (structural or cosmetic damage). 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.

An automated

noise survey

will involve the installation of

noise and vibration monitors

for a minimum of 24hrs. The acquired data will be used to assess the noise or vibration profile of an area, identify any specific noise or vibration sources and provide further statistical information which, in most cases, will assist in setting noise emissions criteria for planning applications (PPG24, BS4142) or provide information on long-term effects of vibration on people or buildings. The most common application for long-term noise and vibration monitoringis in construction sites or other permanent operations such as quarries. In this case, a number of

noise and vibration monitors

will be deployed within or around a site, allowing the continuous logging of noise and vibration data. Alarms can be set should pre-defined trigger levels be exceeded, while notifications (SMS, email) can be sent instantaneously in order to allow the unimpeded progression of all site works.

Our team of experts will be able to respond swiftly to your enquiry for any noise and vibration scenario. Our experience in all types of

noise monitoring

, be it a 24hr survey or long-term monitoring at one or multiple locations, will allow us to deliver a robust result which would assist towards the successful completion of your project.

Noise mitigation

is a set of strategies to reduce

noise pollution

. The main areas of noise mitigationor abatement are: transportation

noise control

,

architectural design

, and occupational noise control. Roadway noiseand aircraft noise are the most pervasive sources of
environmental noise
worldwide, and little change has been effected in source controlin these areas since the start of the problem,[citation needed] a possible exception being the development of hybrid and electric vehicles. Noise pollution is excessive, displeasing human, animal, or machine-created
environmental noise
that disrupts the activity or balance of human or animal life. The word noisemay be from the Latin word nauseas, which means disgust or discomfort.[1] The source of most outdoor noise worldwide is mainly
construction noise
and transportation systems, including motor vehicle noise, aircraft noise, and rail noise.[2][3] Poor urban planning may give rise to noise pollution, since side-by-side industrial and residential buildings can result in noise pollution in the residential area. This is also to del with noise nuanse. There are several ways of providing

noise and vibration monitoring

As the noise generally everything that we do not want and the pollution in this specific situation is the sound generated by all creatures and machines around us it is important to provide proper

noise monitoring

and as noise is always related with vibration, and they can be created by all means of transport so it is mportant to provide a

smart noise control

 

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 Survey

 

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
