Acoustic Reflex Thresholds in Normal, Cochlear, and Retrocochlear Lesions
The cut off points of 90th percentile of acoustic reflex thresholds were determined in the normal and sensory hearing loss.All subjects had measurable hearing(ANSI-1969≤110 dBHL) in three frequencies of 500,1000 and 2000Hz.While hearing loss was more than 55dB, The cut off point was higher in studie...
