[Stapedial reflex test for gerontal sensorineural hearing loss].
The purpose of this investigation was to find a method that can diagnose sensorineural hearing loss early. Fifty subjects, aged more than 60 years, with hearing level ranged from normal to profound deafness, were examined. The noise-tone difference (NTD) were calculated at 0.5, 1, 2, and 4kHz from these data. The results indicated that NTD at 1kHz was more sensitive than others for diagnosing gerontal sensorineural hearing loss in early stage.
