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.
