Of the total study participants, 83.1% of them used PLDs regularly, of whom 77.7% used it for more than 1 h a day. Overall, 18.0% of the study population was aware that prolonged use of PLDs could be harmful to their health. Majority of the study subjects (72.4%) felt that the safe duration of listening to PLDs is 3 to 5 h. Among the subjects using PLDs ≥ 1 h, 60.1% preferred ear phones and among those using PLDs <1 h, 44.1% preferred earphones. Overall, 12.4% experienced temporary hearing loss on usage of PLDs. The use of PLDs among the medical students is on the rise, and they should be made more aware of the harmful effects associated with its use.
