ears loweredとは 意味・読み方・使い方

Electric continuous vibrations are supplied to the specified electroacoustic transduction apparatus 13 to output a sound wave S, which is picked up by a sound pickup microphone 15 and outputted to be heard with headphones 20, wherein sound pressure applied to the ears of a listening worker is lowered by reducing the fundamental wave component thereof to facilitate the discrimination of the abnormal sound emitted from the electroacoustic transduction apparatus 13 itself.例文帳に追加

電気的な持続振動を特定の電気音響変換機器１３に与えて音波Ｓとして出力させ、該音波Ｓを収音マイク１５で収音してヘッドホン２０での聴音を可能に出力するに際し、その基本波成分を減じることで聴音作業者の耳に加わる音圧を低下させて電気音響変換機器１３自体が発する異常音の聴別を容易化した。 - 特許庁
