Acoustics. Noise from shooting ranges - Sound propagation calculations included-in-kit Note: AdditionallyWhat is ISO 172013 Shooting range sound calculation about? Sounds in our surroundings not only affect our immediate experience, but they can also have long term effects on our hearing. ISO 17201 discusses acoustics from the perspective of noise from shooting ranges. ISO 172013 is the third part of the multi series on noise from shooting ranges, and specifies methods of predicting the sound exposure level of shooting sound for a single shot at a given
