Abstract:

Communication enhancement devices were designed for those who want to maintain natural hearing while protecting their ears from impulse and continuous noises like gunfire, explosions, vehicles, and machinery. There were potential advantages for this technology in military applications, provided an accurate and complete assessment of the performance had been obtained. The OTTO Hurricane with Invisio V60 and Sonic Defenders EP4 earplugs were assessed for continuous noise attenuation, sound localization, and speech intelligibility. The OTTO Hurricane with Invisio V60 and Sonic Defenders EP4 earplugs caused degradation of localization capabilities in comparison to the open ear performance. The OTTO Hurricane with Invisio V60 and Sonic Defenders EP4 earplugs in both open and closed filter conditions met the acceptable speech intelligibility scores less than or equal to 80 correct in continuous noise levels of 65 and 85 dBA.
