Noise Induced Hearing Loss and Auditory Localization
Abstract
Many studies have been conducted on the ability of normal hearing listeners to judge the locations of various sounds. A few researchers have explored the effects of noise induced hearing loss on auditory localization acuity (Noble, Byrne and Lepage, 1994; Smith- Olinde, Koehnke and Besing, 1998; and Lorenzi, Gatehouse and Lever, 1999). These researchers have shown that the use of higher frequency energy in the signal is reduced by high-frequency hearing loss. Elevation acuity is more affected by high-frequency hearing loss than azimuth acuity, which is dominated by interaural time difference cues. Many factors, including the temporal and spectral characteristics of the sound source, the listening environment, the types of interfering sound sources, and the listener's auditory system, affect localization acuity. Two of those factors, the effects of noise-induced hearing loss and head motion cues, are reported in the current study.
