Manufacturers' Sound Data – Application Experiences


  • Pier-Gui Lalonde Integral DX Engineering Ltd., CA
  • Gregory E. Clunis Integral DX Engineering Ltd., CA


In our practice we are regularly provided with manufacturers' sound data, and use it to predict environmental noise levels at noise-sensitive receptors. Frequently we are then able to measure sound pressure levels of the new equipment once installed, allowing us to validate the manufacturer data. This paper discusses the diversity of sound level information that we are given, and presents comparisons between manufacturers' data and measured sound pressure/power levels. Often we find good agreement, sometimes within plus minus 1 dB, and most of the time within plus minus 3 dB. However, there are outliers. Possible causes for the outliers are discussed.
