Acoustics. Noise from shooting ranges - Prediction of projectile sound Ingestion-build-221493 Limited display size1 Scope This part of ISO 17201 provides a computational model 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 guidance on how to use this source level to calculate the sound exposure level at a receiver position. This part of ISO 17201 is intended for calibres of less than 20 mm, but can
