INTRODUCTION: Over the last two decades the use of personal music player (PMP) with
headphones/earphones has increased tremendously. Those people using headphones/
earphones on regular basis belongs from all age groups. They become accustomed to use
headphones/earphones at high volumes and over long periods of time which may be implicated
in ongoing permanent hearing loss in these individuals. Both the intensity and duration of noise
exposure determines the potential for damage of the hair cells of the inner ear. The study
population was the university students using such devices, however audiogram performed only
in participants using these devices for more than 1 hour a day, at moderate to high volumes.
OBJECTIVE: To identify association of sensorineural hearing loss and noise exposure from a
personal music player with head phones/earphones among the young university students.
MATERIAL AND METHODS: This prospective study conducted at Dow International Medical College,
DUHS from January 2015 to April 2015. All Final year students were invited for the survey.
Informed consent was taken from each participant. Data was collected regarding the duration
and hours of use of personal music players. To detect degree of the change in hearing
threshold, Audiograms assessment done on 56 participants from high risk group. The data was
analyzed using SPSS16.
RESULT: The majority of earphone users are young adults. The audiogram showed mild hearing
loss in frequencies over 0.5- 8 kHz.
CONCLUSION: There is mild hearing loss in the high risk group, therefore adequate counseling,
for these individuals, regarding change of their listening habits is necessary if further hearing
loss is to be prevented.
Key words: Audiogram, recreational hearing loss, earphone, over the ear head phone,
personal music player.
