Abstract: Various embodiments are directed to an outsole for a footwear article. In various embodiments, the outsole comprises a forefoot outsole portion defining a forefoot portion bottom surface configured for contact with a ground surface; a heel outsole portion defining a heel portion bottom surface configured for contact with the ground surface; a bridging portion defined between the forefoot outsole portion and the heel outsole portion, the bridging portion having a recessed configuration relative to the forefoot outsole portion and the heel outsole portion such that the bridging portion defines a bridging portion cavity that extends between the forefoot outsole portion and the heel outsole portion; and an arc-shaped bridge that extends along the bridging portion and is configured to be disposed out of an adjacent bridging portion surface of the bridging portion such that the arc-shaped bridge is defined by a bridge height protruding from the adjacent bridging portion surface.

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: 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.
