BACKGROUND During ground operations, rotary-wing aircraft engines and subsystems produce noise hazards that place airfield personnel at risk for hearing damage. The noise exposure levels outside the aircraft during various operating conditions, and t

The report details insertion loss measurements from multiple types of hearing protection devices in order to examine the nonlinearity of insertion loss. Tests were conducted in continuous noise from 55 to 130 decibels (dB) and impulsive noise from 11

Objective: Workers with hearing loss face special problems, especially when working in noise. However, conventional hearing conservation practices do not distinguish between workers with normal hearing versus impaired hearing. This study collected in

The report covers the results of testing four passive hearing protection devices for continuous noise attenuation using the Real Ear Attenuation at Threshold (REAT) test, the Impulsive Noise Insertion Loss (IPIL) test, and for localization performanc

Hearing loss is one of the most common occupational injuries in the Department of Defense. One reason is limited access to adequate hearing protection during combat operations. Even if traditional pre-formed foam earplugs are used during combat, appr

Commonly, attenuation and comfort are the major criteria used in selecting a hearing protective device (HPD) for a given noise environment. The objective of this study was to develop a method of HPD selection in which speech intelligibility is introd
