B, especially prolonged exposure. • Current hearing protection is inadequate. Personnel are often overexposed in seconds or minutes. • Performing your duty can present your hearing with noise levels that require hearing protection to avoid joining the ranks of those who have suffered hearing loss disability as a result of their service. Examples of damaging noise levels encountered in military environments. © Westone Laboratories, Inc. 2016
