Abstract
Tinnitus, the perception of sound in the absence of an external acoustic source, disrupts the daily life of 1 out of every 200 adults, yet its physiological basis remains largely a mystery. While tinnitus and hearing loss (i.e., elevated pure tone thresholds) commonly co-occur, many people without hearing loss experience tinnitus, raising the question of whether cochlear pathology is always a prerequisite for this percept. This study used distortion product otoacoustic emissions (DPOAEs) to evaluate the cochlear amplifier of 13 tinnitus subjects and 13 non-tinnitus subjects (matched by age, sex, and audiogram) across a broad range of frequencies and intensities. DPOAE magnitudes were measured for at least 52 frequencies (500 Hz
