대학생의 이어폰 사용, 스트레스 및 청력의 관계

Abstract

Purpose: The purpose of this study was to investigate the relationship among use of earphones, stress level, and hearing threshold in university students. Methods: Study subjects included 210 university students (76 men, 134 women). Data were collected by questionnaire and audiometer from December 17 to 20, 2011. The SPSS win 19.0 program was used for data analysis by descriptive statistics, t-test, one-way ANOVA, and Pearson"s correlation coefficient. Results: 1) 4KHz, 6KHz hearing threshold of subjects who used earphones was higher than average hearing threshold of same age group. 2) Not significant differences in hearing threshold were observed according to frequency of use, and stress level. 3) Significant differences in 4KHz hearing threshold were observed according to earphone volume. 4) A significant positive correlation was observed between frequency of use and stress level (r=0.15, p<.05), earphone volume, and 4KHz hearing threshold (left) (r=0.15, p<.05); however, a negative correlation was observed between stress level and 4KHz hearing threshold (right) (r=-0.14, p<.05). Conclusion: A significant positive correlation was observed between frequency of use and stress level and earphone volume and 4KHz hearing threshold (left). Development of a program for hearing conservation is needed.
