| Abstract(in English) | To measure the diffuse-field sensitivities of condenser microphones, we constructed a pure-tone field in a reverberation box, to get the high precision measurement by the reciprocity method. The sound source and receptor microphones were moved up and down by rotary systems, so that many spatial pressure field samples could be obtained. The compensation quality of diffuse field characteristics was obtained from a coupler response. The results compared well with published measurements obtained by other methods. |
