EVALUATION OF HEARING ACUITY IN YOUNG ADULTS USING PERSONAL LISTENING DEVICES WITH EARPHONES
Journal Title: International Journal of Basic and Applied Physiology - Year 2018, Vol 7, Issue 1
Abstract
Background: There is a growing concern regarding the hearing health of the young adults, because now a day the usage of personal listening devices and mobile phones with earphone or headphones has increased tremendously in youth. Long term use of these devices with high intensity of sound could bring irreversible damage to auditory system. Aim and Objective: The aim of this study is to investigate the hearing acuity of young adults using personal listening devices (PLDs) with earphones and nonusers and to evaluate effect of listening habits on hearing. Materials and method: It is a comparative study. Total 500 subjects selected randomly containing two subgroups 250 subjects of test group using earphones and 250 subjects of control group not using earphones from both the sex between age group of 18 – 40 yrs. Before commencing pure tone audiometry on total 500 subjects, questionnaire was filled by subjects regarding age, sex, self-reported hearing problem, duration of usage and type of personal listening devices used by them. The data obtained is statically analysed by SPSS version 19 and chi square method. Results: Our results showed significant differences in mean hearing threshold level at low and high frequency in right and left ear between test group and control group. In present study we obtained significant fair positive correlation between mean hearing threshold level and usage of sound devices/day/year in Rt and Lt.ear with Low and high frequency. Our results also revealed that significant association is found between usage of earphone/day and hearing impairment. Conclusion: Usage of personal listening devices with earphones for longer time with high intensity of sound leads to early hearing loss and the frequency of mean hearing threshold level is higher in earphone users than nonusers.
