Iso 9613 specifies an engineering method for the calculation of sound attenuation during outdoor propagation in order to predict ambient noise levels, at a distance from a variety of sources. the method predicts the equivalent continuous sound pressure level with a-weighting filter in favorable weather conditions for the propagation of noise emission sources
Determine the accuracy of the sound propagation method proposed in iso 9613 for the prediction of sound pressure levels generated by fixed sources.
It is intended to improve the prediction algorithms
