This preliminary study found no hearing damage in rats exposed to 900 MHz radiation, but lacks key exposure details needed for safety conclusions.

Plain English Summary

Summary written for general audiences

Italian researchers exposed rats to 900 MHz microwave radiation (the same frequency used by early cell phones) to see if it would damage their hearing or inner ear function. After testing the rats' cochlear receptors (the delicate structures in the inner ear that convert sound waves into nerve signals), they found no statistically significant hearing damage at the radiation levels tested. The study was designed as preliminary research to establish testing methods for investigating potential hearing effects from microwave exposure.

Study Details

The purpose of this paper is to present the experimental device and the work in progress performed in search for objective organic correlation of damage to hearing, examining possible acoustic otofunctional effects on the cochlear epithelium of the rat due to exposure to microwaves (900 MHz).

Two experiments using male Sprague-Dawley rats were carried out with a far-field exposure in a cubic...

No statistically significant evidence was obtained at both specific absorption rate (SAR) values.

The exposure system and the diagnostic apparatus are extremely useful to investigate a potential effect on the auditory system: however, with the parameters applied in these experiments, no evidence was observed.
