: Active electronic hearing protection devices are designed for those who want to maintain natural hearing while protecting their ears from impulse and continuous loud 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. Five active hearing protection devices were assessed for: continuous noise attenuation, impulsive peak insertion loss, sound localization, auditory detection, and subjective comfort. The expected ambient noise environment and the task to be performed should be considered when selecting a hearing protection device.
