RESULT:1) The rate of holding MP3 in the middle school students was 85.2%. Average daily use time was (1.41 +/- 1.11) h. 2) The noise group of pure tone hearing threshold was significantly higher compared with the control group (P<0.01), and increased the detection rate of hearing loss with the increasing use of MP3. 3) The detection rate of symptoms increased with the increasing use of MP3.
