Over deze norm
If possible, the source data of muzzle blast and the source data of projectile sound should be determined according to part 1 and part 4 of this standard, respectively. ISO 17201-2 addresses those cases where no source measurements exist, or where the data necessary to calculate projectile sound according to part 4 are not known, which is the case, for example, for the projectile sound from pellets fired from shot guns. This part of ISO 17201 can also be used as an interpolation method between measurements of muzzle blast. Source data are given in terms of spectral angular source energy covering the frequency range from 12,5 Hz to 10 kHz and can be used as data input for sound propagation calculation. This part of the standard is not applicable to the prediction of sound levels for the assessment of hearing damage, neither can it be used to predict sound pressure levels or sound exposure levels below a specific distance where linear acoustics does not apply.
