Abstract
A communication device for communications between the inside and outside of a room through a partition. The communication device comprises an indoor set including a receiver microphone for picking up the voice of an outdoor person, a receiver amplifier and an indoor speaker for outputting the voice amplified by the receiver amplifier, and an outdoor set including a transmitter microphone for picking up the voice of an indoor person, a transmitter amplifier and an outdoor speaker for outputting the voice amplified by the transmitter amplifier. The communication device further comprises a band-pass filter and a detection circuit separately of a line connecting the transmitter microphone and the transmitter amplifier. The band-pass filter passes the band which is occupied by the fundamental frequency of the voice uttered by a person. The detection circuit detects the voice passed. The communication device attenuates or turns off, when it detects the voice, the output of the voice amplifying system on the receiver side.
