A wide-band acoustic impedance and reflectance system (D. H. Keefe, R. Ling, &amp; J. C. Bulen, 1992) was investigated as a means of obtaining reflex thresholds at a reduced level and as a means of providing a more complete characterization of the reflex than current clinical methods provide. Reflex thresholds obtained by measuring changes in wide-band admittance, reflectance, and power were at least 8 dB lower than those obtained with the standard clinical technique. These reflex-induced changes were accounted for by a simple oscillator model of the middle ear, assuming that the acoustic reflex results in an increase in stiffness. The results support further investigation of reflectance-based measures of the acoustic reflex as a clinical tool and as a means of studying the reflex mechanism.<\/jats:p>","DOI":"10.1044\/jslhr.4205.1029","type":"journal-article","created":{"date-parts":[[2014,7,29]],"date-time":"2014-07-29T21:04:40Z","timestamp":1406667880000},"page":"1029-1041","source":"Crossref","is-referenced-by-count":68,"title":["Acoustic Reflex Detection Using Wide-Band Acoustic Reflectance, Admittance, and Power Measurements"],"prefix":"10.1044","volume":"42","author":[{"given":"M.
