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.

  • after exposure

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.
