exposure investigate the effects of RF exposure to humans in a controlled laboratory environment to determine potential RF effects on relevant biological endpoints including changes in electroencephalogram (EEG) amplitudes, increase in blood pressure, sleep disturbances, cardiac arrhythmia, changes in cognitive performance, and headaches.

It is generally recognized that the interpretation of EEG findings is difficult because of the high intra-individual variability in attention and waking state of volunteers. Some of the waking EEG studies reveal an enhancement of cortical activity, as measured by the increase of spectral power in the alpha band during RF exposure.

At present, however, there are very few experimental data from human volunteer studies concerning health problems with auditory prostheses. Effects on heart rate and blood pressure Acute changes in the blood pressure and in other cardiophysiological parameters during RF exposure have been studied using healthy adult volunteers.

The number of reported symptoms was higher during sham exposure than during RF exposure, which could have been due to higher postural and mental tension at the beginning of the experiment when subjects were not yet adapted to the experimental conditions. In another study, persons with self-reported sensitivity to mobile phone signals did not react to RF exposure with any increased severity of perceived symptoms (Rubin et al.

Finally, there is a continuing need for experiments focusing on possible adverse RF effects identified by changes in cognitive performance functions. Research Needs There are some considerable research needs for human laboratory studies.

32 IDENTIFICATION OF RESEARCH NEEDS Judged to Be of Lower Priority 4. Because the use of cell phones by individuals with auditory prostheses is increasing, there is a need to conduct human volunteer studies to investigate potential ����������������������������������������������������� health implications arising from��������������������� interaction of cell phones with hearing aids and cochlear implants.
