Effects of the electromagnetic field of mobile telephones on hearing. med./bio.

Published in: Acta Otolaryngol 2002; 122 (3): 289-293

Aim of study (acc. to author)

To study the acute after-effects to the electromagnetic fields emitted by mobile phones on human hearing as determined by alterations in evoked otoacoustic emissions.

Main outcome of study (acc. to author)

No measurable change in evoked otoacoustic emissions was revealed and none of the subjects reported a deterioration in hearing level. It was concluded that a 10-min exposure to the electromagnetic field emitted from a mobile phone had no effect on hearing, at least at outer ear, middle ear and cochlear levels.
