Sixty-seven cases of nonorganic hearing loss who visited our clinic between 1989 and 1996 were studied. Females are more frequent rather than males and the male/female ratio is about 1:4. Pure tone audiograms in these cases showed a flat-shaped sensorineural hearing loss in 77 ears (72%) and its hearing level ranged in 30-49dB in most cases Although 37 patients had hearing loss and another cochlear symptoms, 30 cases were found their hearing impairment on audiogram in the school screening hearing test. Twenty-two patients of 30 cases had psychological problems related to troubles of school and family, etc.
Bekesy audiogram showed type V of Jerger's classification in 67 ears (88%). Bekesy audiometry, ABR and transient evoked otoacoustic emission (TEOAE) recordings were useful for diagnosis of nonorganic hearing loss.
