This study found no immediate hearing damage from 900 MHz cell phone radiation in rats, but limited exposure details prevent broader conclusions.

Plain English Summary

Summary written for general audiences

Researchers exposed rats to 900 MHz electromagnetic fields (the same frequency used by many cell phones) and measured their hearing function using specialized tests that detect the health of inner ear cells. The study found no significant changes in hearing function during or after EMF exposure. This suggests that cell phone radiation at 900 MHz may not directly damage the delicate hair cells in the cochlea that are essential for hearing.

Study Details

The auditory system is a major target of exposure to electromagnetic fields (EMF) emitted by cellular telephones; the aim of this study was the evaluation of possible effects of cellular phone-like emissions on the functionality of rat's cochlea.

Distortion Products OtoAcoustic Emission (DPOAE) amplitude was selected as cochlea's outer hair cell...

No significant variation due to exposure to microwaves has been evidenced.
