Noise characteristics of the receiving electroacoustic channel with an electret condenser sensor of speech signal have been considered in the paper. The technique for optimizing the converter' characteristics by inner electrical noise of the signal amplifier as well as the sensor's experimental amplitude-frequency response have been given. It has been found that in order to suppress noise generated by the amplifier it is advantageous to have a Q -factor within 2 4 and resonance frequency ω 0 in the range of 0.7 0.85 ω 2 in the condenser converter.
