To study whether low-level radiofrequency stimulation from mobile phones has an effect on peripheral auditory and/or vestibular function, and to study whether some individuals who report symptoms after mobile phone use have a demonstrably greater change in peripheral auditory and/or vestibular function, than individuals who do not report such symptoms.
|Exposure duration||continuous for 30 min|
|Repetition frequency||217 Hz|
There were no significant transient evoked otoacoustic emissions (TEOAE) changes from baseline to post-exposure recording for any of the exposures and no significant differences in the TEOAEs change from baseline to post exposure between cases and controls.
The data of vestibulo-ocular reflex did not show any effect of the exposure on the vestibular end organ in either cases or controls.
In conclusion, 30 min exposure to mobile phone radiofrequency did not show any immediate effects on vestibulo-cochlear function.
