Abstract
Disclosed are hearing protection devices and housings for noise sensors for the same. Hearing protection devices can include an ear cup including an external casing partially defining an inner space, a noise sensor including a microphone electrically coupled to a printed circuit board, and a housing disposed in an aperture defined in the external casing. The housing can define an axial bore defining a noise sensor receiving portion and an acoustic communication portion. The inner space of the ear cup can be substantially airtight when the housing is sealably disposed at or proximate the aperture, the microphone is engaged within the noise sensor receiving portion of the housing, and the ear cup is worn securely about the wearer's ear. The noise sensor can be calibrated by removing a removable securing collar and slidably disposing a calibration tool into the axial bore without further disassembling the hearing protection device.
