STANDARD CONDITIONING METHOD FOR HANDSETS WITH CARBON MICROPHONES


ITU-T P.75 SPANISH-1988 发布历史

Since the characteristics of carbon microphones are strongly dependent on conditioning techniques, it is necessary to follow a consistent procedure prior to measuring sensitivity/frequency characteristics in order to obtain reproducible results. The CCITT recommends that for best reproducibility, automatic mechanical conditioning be used.
