Communication enhancement devices are 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 are potential advantages for this technology in military applications, provided an accurate and complete assessment of the performance has been obtained. The Invisio V60 tactical system with the X5 (V60 X5) dual in-ear headset was assessed for: continuous noise attenuation, auditory localization, and speech intelligibility. The Invisio V60 X5 tactical headset caused significant impairments to localization capabilities in comparison to the open ear performance, and that knowledge must be used to determine how and when such devices can be integrated successfully into a mission. Additionally, the Invisio V60 X5 did not reach acceptable speech intelligibility scores for the current military standards at any noise level. |
