The Assessment of the AH-64D, Longbow, Mast-Mounted Assembly Noise Hazard for Maintenance Personnel

Abstract

Noise levels around the AH-64 helicopter exceed safe limits. Maintenance personnel are required to wear hearing protection to reduce hazard to hearing while performing maintenance procedures. This evaluation was directed at determining the contribution to noise levels by the auxiliary power unit (APU), auxiliary ground power unit (AGPU), environmental control system (ECS), and mast mounted assembly (MMA) at a variety of maintenance positions and establish protection capabilities of standard protectors for those noise levels. Noise levels, AH-64 Helicopter, Hearing protection, Noise hazards.
