View Original AbstractCell phones deposit minimal RF energy in ear structures, making thermal hearing damage unlikely at typical power levels.
Plain English Summary
Researchers created a detailed computer model of the human inner and middle ear to measure how much radiofrequency energy is absorbed from cell phones held near the head. They found that typical mobile phones deposit extremely small amounts of energy in ear structures - less than 166 microwatts even at the highest frequency tested. The study concluded that cell phone radiation is unlikely to cause temperature-related damage to hearing organs.
Study Details
In order to enable a detailed analysis of radio frequency (RF) absorption in the human middle and inner ear organs, a numerical model of these organs was developed at a spatial resolution of 0.1 mm, based on a real human tissue sample.
The dielectric properties of the liquids (perilymph and endolymph) inside the bony labyrinth were me...

These results indicate that temperature-related biologically relevant effects on the middle and inner ear, induced by the RF emissions of typical handheld mobile communication devices, are unlikely.
