Validation of the Single-Impulse Correction Factor of the CHABA Impulse-Noise Damage-Risk Criterion

Abstract

Seventy-six subjects were exposed to single impulse noises produced by two small shoulder-fired rockets, and TTS2 (temporary threshold shift) was compared with the Committee on Hearing, Bioacoustics, and Biomechanics (CHABA) limits. The single impulse, 95% protection, and grazing incidence correction factors of the CHABA damage-risk criterion were validated. Grazing-incidence shock waves produced comparable results when they arrived at the ear from the front and from the rear.
