Abstract
The invention concerns a hearing device for a protective helmet with a receiving deice for auditory signals, that at the very least are deliverable from the earphones arranged on the inner surface of the protective helmet. The invention has as its basic function to reduce the volume of the helmet contruction and the weight of the hearing device in relation to the usual construction, and to make the positioning of the earphones on the ears of the helmet wearer unnecessary. The purpose will be met in that the earphones in the outer auditory canal of the helmet wearer will be developed as importable earplugs. The auditory signals that are supplied by a receiving device consisting of a receiver and a coupled transmitter will be transmitted from the transmitter of the receiving device over a wireless transmission line that is integrated into the earplug-receiver of the earplug.
