This study was designed to explore the possibility of using facilitation of the acoustic reflex to determine peripheral frequency selectivity. Changes in reflex magnitude in response to a 2000-Hz tone burst presented at 5 dB above reflex threshold were measured as a function of the frequency and level of a facilitating stimulus presented in a nonsimultaneous paradigm. 3 normally-hearing adults served as subjects. Results reveal that acoustic reflex facilitation does not appear to be a frequency-dependent phenomenon thus suggesting that the tonotopic organization of the cochlea is not preserved at the site of reflex facilitation.
