Does EMF Affect Hearing?

Effects of chronic exposure to electromagnetic waves on the auditory system
Published in Acta Otolaryngol. 2015 Apr 2:1-6.
Objective:  Study evaluates the effects of the electromagnetic waves emitted by mobile phones.
Conclusion: The results support that chronic electromagnetic field exposure may cause damage by leading to neuronal degeneration of the auditory system.
Method: The rats were divided into two groups of six rats. The study group was exposed to the electromagnetic waves over a period of 30 days. The control group was not given any exposure to the electromagnetic fields. After the completion of the electromagnetic wave application, the auditory brainstem responses of both groups were recorded under anesthesia. The degeneration of cochlear nuclei was graded by two different histologists, neither of whom knew what group each rat belonged to.
Results: Neuronal degeneration signs, such as increased vacuolization in the cochlear nucleus, pyknotic cell appearance, and edema in the group exposed to the electromagnetic fields compared to the control group.
