Study Type Human / Provocation
Model 900 MHz (GSM) exposure to humans and analysis of EEG and auditory evoked potentials

Human subjects (n=20; 10 males & 10 females) were exposed to 900 MHz GSM signals from cellular telephones emitting a maximal peak power of 2 watts (peak SAR in the temporal brain region ~ 0.1 W/kg) for 1 hour. Auditory brainstem responses (ABRs) from a stimulus source delivering 100-usec clicks at 80 - 90 dB, and auditory distortion products (ADP), were measured before and after the 1 hr exposure. No significant difference were observed in the ABRs between pre- and post-exposure recordings. A significant difference in ADP occured only at 2 isolated frequencies (65 and 55 dB), and this result was interpreted by the investigators as not seeming to have physiologic meaning.
