ABSTRACT:
The invention relates to a noise damping headset comprising at least one microphone and at least one ear phone intended to be connected via electrical conduits, preferably wires, to a transmitter and a receiver, preferably a mobile telephone, a communication radio or the like for communication between persons. The microphone consists of throat microphone for direct or indirect contact against the skin around a throat, the equipment mainly being sound tightening for sounds, coming from outside, from emerging into the throat microphone and the ear phone comprises a funnel-shape for inserting the same into the auditory canal of a person's ear, the outer limiting surfaces of the funnel-shape being sound tightening against the walls of the auditory canal, the sound coming from outside being prevented from emerging into the auditory canal, whereby a communication between said persons can be held without being disturbed in a greater extent of the sound coming from outside.
