Noise Attenuation Performance of the HGU-25/P Flight Deck Helmet Integrated with the Argonaut Headset and CEP-Custom Communication Earplugs

Abstract

Noise attenuation performance measurements were collected at the Air Force Research Laboratory's (AFRL) Battlespace Acoustics Branch at Wright Patterson Air Force Base from June - July of 2013. Passive noise attenuation was measured using ANSI S12.6-2008 Methods for Measuring the Real-Ear Attenuation of Hearing Protectors, Method A.1 All real-ear attenuation at threshold (REAT) measurements were completed with the HGU-25/P flight deck helmet integrated with the Argonaut headset and CEP-custom communication earplugs. The noise attenuation results for the passive double hearing configuration are reported for each individual subject as well as mean and standard deviation for all subjects from 125 Hz to 8kHz.
