Noise Measurement

Definitions Threshold and criterion levels The threshold level is the A-weighted sound level at which a personal noise dosimeter begins to integrate noise into a measured exposure. For example, if the threshold level on a sound level meter is set at 80 decibels (dB), it will capture and integrate into the computation of dose all noise in the ...

Integrated noise calculation and evaluation according to the EU directive on environmental noise

by SoundPLAN International LLC  (Nov. 11, 2009)

The model data for acoustic calculations already contains essential characteristics for more in depth evaluation of the results (i.e. building heights, number of storeys, or ground space per storey). With additional information such as building usage and number of inhabitants, the evaluation and graphical representation of the results can be ...
