Claims (1)
伝播管の側面に面一にかつ軸方向同一位置に複数
の圧力変換器を接続し得る検出部を設け、スピー
カで発生させる高周波を有する振動圧力波を上記
伝播管内を平面波で進行させると共に各圧力変換
器の感圧部に同位相で到達させたことを特徴とす
る圧力変換器の位相伝達特性差検定装置。 A detection section to which a plurality of pressure transducers can be connected is provided flush with the side surface of a propagation tube whose one end is connected to a speaker and the other end is a closed end, and the vibration having a high frequency is generated by the speaker. A pressure transducer phase transfer characteristic difference testing device characterized in that the pressure wave is caused to travel in the propagation tube as a plane wave and to reach the pressure sensing portion of each pressure transducer in the same phase.
