PROBLEM TO BE SOLVED: To provide a device for evaluating inner ear properties that can evaluate inner ear properties, in a noninvasive manner and without depending on answers from a subject.SOLUTION: The device has: a stimulation sound presenting unit for presenting a stimulation sound as an amplitude modulation sound to the external auditory canal of an evaluation subject an ear acoustic radiation calculation unit for calculating ear acoustic radiation occurring from the presented stimulation sound and a display unit that displays information such that the user can visually confirm whether or not there is a remarkable peak in the phase modulation amount of ear acoustic radiation to the stimulation sound.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2019,JPO&INPIT【課題】非侵襲かつ対象者の解答に依存せずに、内耳特性を評価することができる内耳特性評価装置を提供する。【解決手段】振幅変調音である刺激音を被評価者の外耳道に呈示する刺激音呈示部と、刺激音の呈示によって生じた耳音響放射を算出する耳音響放射算出部と、刺激音に対する耳音響放射の位相変調量に目立ったピークが存在するか否かを視認可能な情報を表示する表示部とを含む。【選択図】図4
