Aim of study (acc. to author)

To examine the possible acute effects of radiofrequency exposure emitted by GSM cellular phones. Auditory brainstem response have been recorded before and after the short-term exposure from the common used handy-devices.

Endpoint

changes on auditory system

Exposure

- mobile communications
- GSM

Exposure	Parameters
Exposure 1: RF (≥ 10 MHz) Modulation type: pulsed Exposure duration: continuous for 15 min	power: 2 W peak value

Exposure 1

Main characteristics

Frequency	RF (≥ 10 MHz)
Type	electromagnetic field
Exposure duration	continuous for 15 min

Modulation

Modulation type	pulsed
Additional info	GSM

Exposure setup

Exposure source	cellular phone
Setup	The cellular phone was positioned close to the head while the subjects were lying with their eyes closed in an electrically shielded area.
Additional info	The output power and the status of the phone (on/off) were controlled by a computer without the knowledge of the subject.

Parameters

Measurand	Value	Type	Method	Mass	Remarks
power	2 W	peak value	unspecified	-	-

Exposed system:

human
partial body: head

Methods Endpoint/measurement parameters/methodology

effects on the neurological system: ABR (auditory brainstem response; see above)
changes on auditory system, ABR (auditory brainstem response)

Investigated system:

after exposure

Main outcome of study (acc. to author)

Wave V latency on the exposed side increased significantly compared to its baseline. A hearing deficiency was found on exposed side only.
