To study whether mobile phone emissions could affect cochlear or auditory brain stem functions.
In a previous study (see publication 11540), the authors could not prove any impact on the vestibular part of the inner ear .
| Frequency | 889.6 MHz |
|---|---|
| Type | |
| Exposure duration | intermittent, 3 min on/off, see "add. information" |
| Exposure source | |
|---|---|
| Chamber | The volunteer was in a lying position in an easy chair. |
| Setup | Exposure to EMF was provided by a special setup described in detail in the reference article. Two mobile phones, with power supplied by an external generator, were mounted to a special chair and could be activated alternately. |
| Additional info | There were three recording sessions with a duration of about 3 min and a break of 3 min in-between: first without EMF, then two sessions with exposure to pulsed or continuous EMF. |
No impact on auditory brain stem reflexes in terms of absolute and interpeak latencies could be revealed.
Together with the data of the previous study (see publication 11540) concerned with the vestibular part of the inner ear, the authors can state that there are no adverse effects of mobile phone emissions on the ear function, at least on a short-term range. Any long-term effects cannot be excluded by the study.
