Environmental Noise

Environmental noise is the summary of noise pollution from the outside, caused by transport, recreational and industrial activities.

For consideration: Generally it is best to engage an acoustic consultant if you have a need for an acoustic barrier or acoustic enclosure.
Many common mistakes or false assumptions are often made in respect to these items which can lead to their providing virtually no noise reduction at all.

industrial and environmental acoustic panelsBarriers and Booths

  • A noise barrier must at least block the line of sight between the noise source and the receiver. As long as this is wide enough this can give an insertion loss of 5dBA but it is best if it is at least 30% higher than this where it could achieve a 10dBA insertion loss.
  • A barrier must have enough mass so that the noise is forced over it and not through it.
  • This would generally be in the region of 1520kg/m2.
  • A properly designed barrier can give an extra 1dBA for each extra metre of height over and above the line of sight.
  • A barrier must be placed as near to the noise source as possible. 
  • A noise barrier may require an absorptive face depending on the noise problem.
  • A noise barrier is unlikely to give more than a 20dBA insertion loss.
  • A noise barrier needs to be wide enough. It should be 810 times as long as the distance between the receiver and barrier itself with the receiver position being central to the barrier length.
  • The enclosure should not be tight fitting, space is required around the enclosure which will depend on the spectral content of the noise.
