An example of this situationwould be measuring projectile sound from shot guns pellets. This part of ISO 17201 can also be used as aninterpolation method between measurements of muzzle blast.Source data are given in terms of spectral angular source energy covering the frequency range from 12,5 Hzto 10 kHz and can be used as data input for sound propagation calculation.This part of ISO 17201 is not applicable to the prediction of sound levels for the assessment of hearingdamage and cannot be used to predict sound pressure levels or sound exposure levels below a specificdistance where linear acoustics does not apply.【中国标准分类号】: Y55【国际标准分类号】: 17_140_20;95_020;97_220_10【页数】: 31P;A4【正文语种】: 英语
