Abstract
This study examined stapedial reflex recordings of pulsed pure tones (500, 1,000, 2,000, and 4,000 Hz) in 26 subjects with normal hearing and 18 with sensorineural impairment. The stapedial reflex tracings clearly differentiated the two groups of subjects. Like many of our special audiometric procedures, this test was least effective in those with mild hearing loss. The test also appeared to be useful in identifying high-frequency hearing losses. Although this reflex measurement appears to have potential as a clinical tool, additional field study appears necessary.
