Abstract
Systems and methods for check a relative sensitivity of two or more microphones of a hearing protection device include sensing ambient sound using two or more microphones of the hearing protection device and sampling the ambient sound. The samples of the ambient sound may be used to determine whether the ambient sound is adequate for determining microphone sensitivity and to determine whether a threshold relative sensitivity of the two or more microphones is reached. A pass or fail indication may be provided to a user based on whether the threshold relative sensitivity is reached.
