Extended high frequency audiometry in users of personal listening devices

In present study no significant changes were noted in hearing thresholds in PLD users before 5 years of PLD use. However, hearing thresholds were significantly increased at 3 kHz, 10 kHz, 13 kHz in PLD users having > 5 years usage at high volume. Thus, it can be reasonably concluded that extended high frequencies can be used for early detection of NIHL in PLD users.
