PROBLEM TO BE SOLVED: To provide methods and apparatus for acoustic detection for automated devices such as respiratory treatment apparatus.SOLUTION: Acoustic analysis of noise or sound pulses, such as a cepstrum analysis, based on signals of a sound sensor 104 permits detection of obstruction O, e.g., within a patient interface, within a mask or respiratory conduit 108 or within patient respiratory system. Some embodiments further permit detection of accessories such as an identification of the accessories or a condition of use of the accessories, such as a leak, thereby permitting detection of a patient or user who is intended to use the automated device. 【課題】呼吸治療装置等の自動化されたデバイス用の音響検出方法及び装置を提供する。【解決手段】音センサ１０４の信号に基づく、ケプストラム解析等のノイズ又は音パルスの音響解析により、患者インターフェース内、マスク若しくは呼吸導管１０８内、又は患者呼吸器系内等の閉塞Ｏの検出が可能になる。付属品の識別、又は漏れ等の付属品の使用の状態等、付属品の検出がさらに可能になるので自動化されたデバイスを使用するように意図されている患者又はユーザの検出が可能になる。【選択図】図１
