PROBLEM TO BE SOLVED: To provide an inner ear characteristic evaluation device capable of evaluating an inner ear characteristic though the device is non-invasive and independent of a target persons answer.SOLUTION: An inner ear characteristic evaluation device includes: a stimulation tone presentation unit 11 for presenting a stimulation tone, which is an amplitude-modulated tone, to an external auditory canal of a person to be evaluated an otoacoustic emission calculation unit 22 for calculating otoacoustic emissions caused by the presentation of the stimulation tone and a phase modulation amount calculation unit 23 that calculates phase modulation amounts of the otoacoustic emissions in response to the stimulation tone and outputs at least any of the maximum value of the phase modulation amounts and the stimulation tones sound pressure at the maximum value of the phase modulation amounts.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2017,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11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22と、刺激音に対する耳音響放射の位相変調量を計算し、位相変調量の最大値、位相変調量の最大値における刺激音の音圧の少なくとも何れかを出力する位相変調量計算部23とを含む。【選択図】図4
