PURPOSE:To provide a sufficient sound-proof effect and property to withstand long-term use and enable the communication of wearing persons with each other by providing the above device with sound-proof materials which fit tightly to the wall surfaces of the external auditory meatus inlets by making adaptive deformation, ear speakers which utter voices toward the external auditory meatus and a microphone which collects the voices uttered by the wearing persons. CONSTITUTION:The conversation collecting microphone 41 which picks up the conversations of the wearing person is mounted at the front end of a conversation collecting part 30. The sound-proof materials 24 are mounted on the inner side of the cups 21. The sound-proof materials 24 are adaptively deformed according to the wearing person 100 to fit tightly to the walls of the inlet of the external auditory meatus 102 of the wearing person 100. The front ends on the external auditory meatus 102 side of the sound-proof materials 24 are bored with sound conduit holes 25 and are arranged with the ear speakers 26 deep in these holes. The wearing persons are able to make conversation with each other by using the ear speakers 26 arranged in the sound-proof materials 24, the conversation collecting microphones 41, IR antennas 31 and IR communication equipment. |
