Acoustic-Immittance Measures in Normal Ears
Terry L. Wiley, Dana L. Oviatt, Michael G. Block · Journal of Speech Language and Hearing Research · 1987
A data base of acoustic-immittance measures in normal adults is presented. The subject pool consisted of 127 adults with normal hearing and a negative otologic history. Norms are presented for hearing thresholds, ipsilateral and contralateral acoustic-reflex thresholds, tympanometry, static acoustic-admittance measures, and middle-ear (tympanogram peak) pressure.
