Abstract

The effect of acute exposure to radio frequency electromagnetic fields (RF EMF) generated by mobile phones on an auditory threshold task was investigated. 168 participants performed the task while exposed to RF EMF in one testing session (either global system for mobile communication (GSM) or unmodulated signals) while in a separate session participants were exposed to sham signals. Lateralization effects were tested by exposing participants either on the left side or on the right side of the head. No significant effect of exposure to RF EMF was detected, suggesting that acute exposure to RF EMFs does not affect performance in the order threshold task.

Main findings

In 168 participants, performance on an auditory order threshold task did not differ between RF EMF exposure (GSM or unmodulated signals) and sham exposure. No significant exposure effect was detected, including when testing left- versus right-side head exposure.

Outcomes measured

  • Auditory order threshold task performance
  • Lateralization effects (left vs right side exposure)

Limitations

  • Exposure parameters (e.g., frequency, SAR) not reported in the abstract
