Abstract: Hearing protection device (10, 10′, 10″) with an indication unit (40a, 40b) and a detection unit (30, 30′, 30″) to send a first detection signal, to assign a distance value based on a second detection signal of an external device (50, 50) representing the physical distance to the external device (50, 50) and to control the indication unit (40a, 40b) to provide an indication to the user (100) if the assigned distance value is at or below a predetermined threshold distance value. Thus, a collision may easily and reliably be prevented by providing an indication to the user (100), so that the risk of missing relevant sound of a moving person or object is overcome. A collision warning system comprising such a hearing protection device (10, 10′, 10″) and an external device is also provided. Furthermore, a method of retrofitting a hearing protection device (10′″) with such a detection unit (30, 30′, 30″) is provided.

Abstract: A method for determining personal protective equipment (PPE) comfort for an individual wearer includes defining a first anatomical shape data representative of an anatomical area of the individual wearer prior to donning a PPE, a second anatomical shape data representative of the anatomical area of the individual wearer after donning the PPE, and comparing the first anatomical shape data with the second anatomical shape data. The method further includes determining a soft skin tissue deformation at a plurality of predetermined anatomical positions based on the comparison between the first anatomical shape data and the second anatomical shape data, and determining a displacement comfort threshold (CTd) value based on the soft skin tissue deformation. The method also includes determining a pressure pain threshold (PPT) value, and determining a comfort metric based on the PPT values and the CTd values. The method also includes generating a notification corresponding to the comfort metric.

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: 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: The present disclosure relates to a short-range communication device (10, 10′, 5 10″) for a personal protective equipment or a personal protective device (200, 210, 220, 230) comprising a transmission unit (20, 20′, 20″) for wirelessly transmitting a voice signal of a user (100, 110, 120, 130, 140, 150, 160) to a receiving unit (40,40′, 40″) over a predetermined distance such that a communication channel is established between the transmission unit (20, 20′, 20″) and the receiving unit (40, 40′, 40″) so that a user (100, 10 110, 120, 130, 140, 150, 160) can hear the voice signal. The present disclosure further relates to a short-range communication system comprising at least two short-range communication devices (10, 10′, 10″) according to the present disclosure and to a method of establishing a short-range communication between such devices (10, 10′, 10″). The short-range communication device (10, 10′, 10″) provides for a communication system 15 for the use with personal protective equipment or personal protective devices (200, 210, 220, 230) with an easy and reliable communication and avoids or minimizes the risk of muffled speech of users wearing a personal protective device (200) such as a respirator (200).
