Abstract

This study surveyed MP3 player usage and evaluated its effect on hearing thresholds in high school students. It is reported an increase in risk factors for hearing loss in adolescents that paralleled the increase in sales of MP3 players. A total of 538 students in two high schools in Gwangju province participated in this study. The students completed questionnaires about their MP3 player use and their pure tone hearing thresholds were tested at several frequencies. The questionnaire results indicated that 61.1%, of the students listened to music on MP3 players for more than one hour per day, 71.6% listened for four or more days per week, and 36.7% had listened for more than 3 years. Listening at a high volume of 60% of the maximum level was reported by 51% and they recognized having ear pains. The pure tone hearing threshold was found to be raised for the adolescents who had a long history of MP3 listening at high volume (p＜ 0.0001).

본 논문에서는 청소년들의 MP3 사용 실태와 그에 따른 청력역치를 평가했다. 청소년들의 MP3 사용률은 지속적으로 증가하고 있으며 청력과 관련하여 위험요소가 되고 있다. 본 연구에서는 광주 지역의 2개 고등학교에 재학 중인 남녀 538명을 대상으로 MP3의 사용 실태를 조사하고 청력 역치를 측정하여 사용 유형별로 상관성을 평가했다. 분석 결과, 하루중 1시간 이상 MP3 사용률이 61.1%였으며, 주당 4일 이상 사용하는 비율이 71.6%이고, 3년 이상 사용한 경우가 36.7% 로 나타났다. 조사대상의 51%가 볼륨 크기를 60%이상으로 듣고 있으며 귀 통증을 인식하고 있었다. MP3를 장시간 사용하며 소리를 크게 듣는 청소년과 그렇지 않은 청소년들의 청력은 유의한 차이가 있는 것으로 나타났다 (p＜ 0.0001).
