Abstract: The present disclosure relates to a hearing protector (10) with a sensor module (30) having a module sensor (32). The sensor module (30) is removably attached to the cushion (22, 24) and the cup (12A, 14A) of the earmuff (12, 14) of the hearing protector (10). The hearing protector (10) according to present disclosure allows the arrangement of sensors at a hearing protector (10) in an easy and cost-efficient way even with multiple sensors. The advantage of such a hearing protector (10) is an easy, compact and reliable solution of a hearing protector (10) providing information about the environment and about the conditions of the user (100) or worker using such a hearing protector (10). Also, a method of retrofitting such a sensor module (30) to a hearing protector (1) is provided. Such a method is advantageous because reversible retrofitting of existing hearing protectors (1) not having the required functionality of sensors is provided.

Abstract: A hearing protection device (10, 10′) comprises at least one earmuff (12, 14) or earplug (12′, 14′), optionally a headband (18, 18′) for carrying the at least one earmuff (12, 14) or earplug (12′, 14′), electronic equipment (13b, 13c, 13d), sound-absorbing material and a haptic sensing unit (11, 11a, 11b) to sense a touch pattern occurring on at least a first portion of the hearing protection device (10, 10′), optionally of the at least one earmuff (12, 14) or earplug (12′, 14′) and/or of the headband (18, 18′). A method of operating a hearing protection device (10, 10′) comprises the steps of providing a haptic sensing unit (11, 11a, 11b) having a haptic sensor (146a, 146b, 146c) configured to sense a touch pattern occurring on at least a first portion of the hearing protection device (10, 10′), optionally of the at least one earmuff (12, 14) or earplug (12′, 14′) and/or of the headband (18, 18′); executing a command when the haptic sensor senses (146a, 146b, 146c) a touch pattern occurring on at least a first portion of the hearing protection device (10, 10′), optionally at least one earmuff (12, 14) or earplug (12′, 14′) and/or of the headband (18, 18′); and triggering a particular state for the hearing protection device (10, 10′) based on the touch pattern sensed, wherein the it provides for a button-less hearing protection device (10, 10′) not requiring space and holes in the outer shell. Just tapping on a portion of the hearing protection device (10, 10′) will initiate operational switching thereof, i. e.—upon sensing of a touch pattern, a command is executed.

Abstract: A ring-shaped cushion for a hearing protector or audio headset. The cushion has a circumferential contact pad for sealing on a wearer's head and an attachment for sealing with an earmuff. The cushion further has a sound insulation tube that inwardly defines an inner space. The sound insulation tube extends between the contact pad and the attachment. The cushion has a ventilation passage that extends entirely through the cushion between an inlet opening in the contact pad and an area outside of the inner space. The cushion may further include one or more physiological sensors to monitor the health of a wearer.
