Abstract:
A 25-year-old man produced a continuous high-pitched pure tone (6.1 kHz, 37.2-dB sound pressure level) in his right ear. The tone was not audible to the patient. He had sensorineural deafness over 1 kHz with a dip of 45 dB at 6 kHz. The tone was considered to be emitted through the eardrum from the inner ear, ie, a "spontaneous otoacoustic emission".
