SYSTEM FOR PREVENTING HEAD OF SPEECH INTERMISSION

摘要

PURPOSE:To bring a talking into a natural state while decreasing the head of speech intermission of a voice transmitted from other station by providing a variable attenuator for preventing howling only to an output side of a microphone transmitted to an opposite station. CONSTITUTION:Indoor noise in a station A1 is larger than that of a station B2 and a person makes a call via a microphone 5-1 of the station B2. Since a variable attenuator 7 is provided to only the transmission side, the intermission of head of speech due to the delay in a rectifier circuit 9 of the station B2 is caused but since the delay of a rectifier circuit 15 of the station A1 is made independent, the intermission of the head of speech is decreased for the share and the talking is brought into the natural state.
