Abstract: A noise sensor is disposed adjacent a speaker within an ear cup of a hearing protection device. The speaker is disposed within a speaker housing and the noise sensor is disposed within a sensor housing, the sensor housing coupled to the speaker housing such that the noise sensor and speaker remain adjacent one another. The noise sensor includes at least a microphone operably coupled to a printed circuit board. The sensor housing defines an axial bore such that the noise sensor can receive acoustic signals via the axial bore. The sensor housing can be coupled to the speaker housing such that the noise sensor is sealed therebetween and receives acoustic signals via a distal end of the axial bore opposite the speaker. A calibration tool can be disposed to the axial bore via the distal end for airtight calibration of the noise sensor.

Abstract: Embodiments provide for improved determination of whether an audio protector is sufficiently fit to a wearer. By automatically performing the improved fit testing processes described, embodiments may warn users in circumstances where fit of their audio protector is dissatisfactory. Some embodiments include receiving external audio data and internal audio data including a filtered range of frequencies, generating comparative internal data by applying the internal audio data to an inverse attenuation model, identifying an audio processing mode based at least in part on the external audio data and/or the internal audio data, the audio processing mode associated with an audio comparison model, computing energy differential data by applying the comparative internal data and the external audio data to the audio comparison model; and determining a fit result based at least in part on the energy differential data.
