Cell phone radiation showed no hearing damage in guinea pigs at levels up to 4 W/kg, double current phone safety limits.

Plain English Summary

Summary written for general audiences

French researchers exposed guinea pigs' ears to cell phone radiation (900 MHz GSM) for 1 hour daily over 2 months at power levels up to 4 times higher than typical phone use. They found no damage to hearing function or inner ear structures, even when examining the ears immediately after exposure and 2 months later. The study also tested isolated ear tissue from newborn rats and found no cellular damage under microscopic examination.

Study Details

The effects of mobile phone (GSM) microwaves on the ears of guinea pigs were investigated in two in vivo experiments and one in vitro experiment

In the first experiment, three groups of eight guinea pigs had their left ear exposed for 1 h/day, 5...

Repeated-measures ANOVA showed no difference in DPOAE amplitudes or in ABR thresholds between the ex...

These results provided no evidence that microwave radiation, at the levels produced by mobile phones, caused damage to the inner ear or the auditory pathways in our experimental animals.
