assessed the short-term effects
of mobile phone electromagnetic fields on the auditory
evoked potential (BERA) of 18 normal-hearing volunteers.
The handset transmitted microwaves at 900 MHz, the SAR
was 0.82 W/kg, and the position was the right ear. BERA
was done before and immediately after a 15-minute telephone
call. The authors found no significant variation in
waves I, II and V, or in the interpeak intervals I-III, III-V
and I-V
