The present disclosure relates to a hearing protection device (″) with an indication unit () and a detection unit (″) to send a first detection signal, to assign a distance value based on a second detection signal of an external device (′) representing the physical distance to the external device (′) and to control the indication unit () to provide an indication to the user () 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 (), 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 (″) and an external device is also provided. Furthermore, a method of retrofitting a hearing protection device (′″) with such a detection unit (″) is provided.
