Is cochlear outer hair cell function affected by mobile telephone radiation? med./bio.

Published in: Clin Otolaryngol Allied Sci 2004; 29 (6): 747-749

Aim of study (acc. to author)

To study whether there is a measurable effect on otoacoustic emissions from pulsed electromagnetic fields (PEMF) irradiation.

Frequency 900 MHz–1.8 GHz
Type
Additional info Frequency range is not mentioned in the article. The frequency range stated here is that of a typical GSM mobile phone.
Modulation
Modulation type pulsed
Exposure setup
Exposure source
Setup The test subjects were exposed to a mobile phone that was placed over the mastoid process of the test ear. They had Otoacoustic emissions measured without the phone and with the phone on receive and transmit.
Additional info The volume of the mobile phone was set to minimum to remove any noise effect. The ambient noise throughout the test was below 40 dB.
Parameters

  • during exposure

Main outcome of study (acc. to author)

There was no statistical difference between the subject responses. This would indicate that pulsed electromagnetic fields (PEMF) from commonly available mobile phones have no measurable effect on the outer hair cell function during the time of use.
