Abstract

Background:

The Bluetooth wireless headset has been promoted as a ‘hands-free’ device with a low emission of electromagnetic radiation.

Objective:

To evaluate potential changes in hearing function as a consequence of using Bluetooth devices, by assessing changes in pure tone audiography and distortion production otoacoustic emissions.

Design:

Prospective study.

Materials and methods:

Thirty adult volunteers were exposed to a Bluetooth headset device (1) on ‘standby’ setting for 6 hours and (2) at full power for 10 minutes. Post-exposure hearing was evaluated using pure tone audiography and distortion production otoacoustic emission testing.

Results:

There were no statistically significant changes in hearing, as measured above, following either exposure type.

Conclusion:

Exposure to the electromagnetic field emitted by a Bluetooth headset, as described above, did not decrease hearing thresholds or alter distortion product otoacoustic emissions.
