Hearing acuity has been estimated in 277 university students of Georgia. 150 from, were regular music player employers while remainder 127 have been not utilized habitually any local music device and constituted thus the control group. Ages of individuals in both sample collections fell in the range of 18-25 years. Auditory thresholds were measured monaurally by the pure tone audiometer within the band of 1-12-kHz frequencies. The overall time of the player service was different among individual admirers while only a restricted number used to listen to the music more than 8 hours per day. At the principal speech frequency link, 1-6 kHz, the thresholds in player music consumers did not differ from those in non-consumers. At 8 and, especially, 12 kHz, however, the player music fans possessed greater thresholds. High-frequency hearing disorders did not display any persistent dependence upon everyday music listening lengths. The process of hearing disturbances along with a group-systematic character seemed thus to own an individual-sensitive quality also. When analyzing the personal data, the gender bearing trend was revealed furthermore: high-frequency threshold elevations appeared in somewhat greater rate in female than in male consumers. Systematic audiometrical inspection of personal music player followers is recommended for an in-time disclosure of a hearing disorder and an immediate start then of corresponding treatment and preventive means. The hearing testing has to include high tone frequencies, 12 kHz, e.g.
