Abstract

This document provides computational methods for determining the acoustical source level of projectile sound and its one-third octave band spectrum, expressed as the sound exposure level for nominal mid band frequencies from 12,5 Hz to 10 kHz. It also gives a method on how to use this source level to calculate the sound exposure level at a receiver position. Results obtained with the standard can be used as a basis for assessment studies for sound around shooting ranges. Additionally, the data can be used to compare sound emission or immission from different types of ammunition used with the same weapon. The prediction methods apply to outdoor conditions and straight projectile trajectories. Two computational methods are given to determine the acoustical source level: one for streamlined projectile shapes and one for non-streamlined shapes, such as pellets.
