以短纯音为刺激声，经受试者正前方２ｍ处扬声器发出，对７例正常人和１０６例感音性聋（单侧９８例、双侧８例），短增量敏感指数（ＳＩＳＩ）试验证实有重振患者行双侧耳蜗微音电位（ＣＭ）测试。９１例在主观重振频率ＣＭ振幅明显加大和延长，其中６２例患耳ＣＭ检测阈与健侧相等或低于健侧，２７例患耳检测阈高于健侧，２例双侧Ｍｅｎｉｅｒｅ病ＣＭ在各自有重振的频率表现出增大及延长现象。部分患耳ＣＭ振幅增大的同时健侧ＣＭ反而减小。全聋及深度聋诱发不出ＣＭ反应。
Short pure tone was used as the stimulus. The sound of 2m at the front of the subject was sent out to 7 normal subjects and 106 patients with sensory deafness (98 unilateral and 8 bilateral), SISI Confirmed patients with revived bilateral bicuspid potentials (CM) test. 91 patients in the subjective re-vibration frequency CM amplitude was significantly increased and extended, of which 62 cases of ear CM detection threshold equal or less than the contralateral healthy side, 27 cases of ear detection threshold higher than the contralateral, 2 cases of bilateral Meniere disease CM The frequency of their own revival showed an increase and prolongation. In some cases, the contractile CM decreased while the amplitude of CM increased. Full deafness and deep deafness can not induce CM response.
