Description
更に、音響法検査とインピーダンス法検査の兼用に限定したため、小型化が可能になり、耳介に接触して擦れ音などでS/N比が低下するのを防止することができる。また、ヘッドバンドなど補助具が不要なので、操作性に優れる。そして、構成要素が少なく、シンプルな筒体構造なので、引物製作が可能であり、金型が不要で少量生産に対する低コスト化が可能となる。
Claims (2)
- 耳管機能検査を行うために外耳道に挿入する耳管機能検査用プローブであって、先端に耳せんを装着した両端開口の第1筒体と、この第1筒体内に空隙を形成して挿入した両端開口の第2筒体と、この第2筒体が当接すると共にマイクロホンとイヤホンを装着した基台を備え、前記空隙がイヤホンから出力される音圧の通路またはマイクロホンへの音圧の通路となり、前記第2筒体がマイクロホンへの音圧の通路またはイヤホンから出力される音圧の通路となることを特徴とする耳管機能検査用プローブ。
- 前記第2筒体の一端に鍔部を形成し、この鍔部が前記第1筒体により前記基台に押圧され、前記第2筒体が前記基台に形成されたマイクロホン音口またはイヤホン音口と連通する請求項1記載の耳管機能検査用プローブ。
