abstract="U.S. Army CH-47D cargo helicopter crewmembers are exposed to high levels of noise on a routine basis, yet must accomplish demanding missions that rely heavily on clear communication. This study looked at the auditory influences affecting communication by 17 crewmembers of a CH-47D Army Reserve unit. Results revealed (1) noise levels that exceed those of other Army rotary-winged aircraft, (2) different exposure levels for aviators and crewchiefs, (3) an overall preference for hearing &quot;critical or diagnostic&quot; aircraft sounds rather than wearing double hearing protection, (4) complaints of post-flight tinnitus or muffled hearing, (5) helmet discomfort among the majority of crewmembers, (6) a high incidence of hearing loss, (7) difficulties in adjusting radio volume controls for aviators, and (8) the effects of eyeglasses or protective masks on hearing and communications.<p /><p>Language: en</p>",
