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 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.

Abstract: Aspects of the present disclosure relate to an ergonomic chestpiece for a stethoscope. The chestpiece includes a bottom surface which is generally planar and adapted to be placed near the patient for receiving auscultatory sounds. The chestpiece includes a raised center portion defining first and second lateral indented gripping surfaces, the raised center portion having a top surface opposite the bottom surface. The chestpiece includes a stem portion extending distally from the raised center portion. The first lateral indented gripping surface is defined by a first wall comprising a first concave surface arcuate about a first axis and the second lateral indented gripping surface is defined by a second wall comprising a second concave surface arcuate about a second axis. The first axis and the second axis form a V-shape comprising an apex oriented in a direction of the stem portion.
