auditory impedanceとは 意味・読み方・使い方

Since the impedance of the damping control circuit is properly changed for each sound region of the reproduced sound corresponding to the acoustic characteristic of the external auditory meatus, the harmful vibration of a diaphragm of the earphone caused by the resonance of the external auditory meatus is effectively damped to make the frequency characteristic of an output or the sound pressure of the reproduced sound almost uniform from a low register to a high register.例文帳に追加

本発明のダンピング制御回路は、外耳道の音響特性に対応して、インピーダンスが再生音の各音域で適切に変化するので、外耳道の共振に起因するイヤホンの振動板の有害な振動が効果的に制動され、再生音の出力又は音圧の周波数特性が、低音域から高音域に亘ってほぼ一様となる。 - 特許庁
