Neuroscientist attarha of mouna (Mouna Attarha), graduated from the University of Iowa and working at the company Posit Science, and researchers from the University of California, San Francisco (USA) came to the conclusion that white noise, which is often used for the treatment of tinnitus, calming and good sleep, can lead to malfunction of the hearing. This publication reports Science Alert.
Tinnitus also called ringing or noise in the ears that is not associated with an external source and can be caused by various reasons, including sulfuric stopper or even neurodegenerative diseases of the brain. People who can’t sleep at night because of the constant ringing in my head, often resorted to the method of masking tinnitus with white noise, such as sounds of waterfall, rain, rustling leaves and other natural sources.
The researchers analyzed scientific articles which described the results of experiments on the effects of white noise on animals. It turned out that long-term exposure to non-traumatic noise causes pathological changes in the Central auditory nervous system that resemble those that underlie tinnitus. This was observed when the volume of 60-70 dB, which is considered a safe noise level.
Thus, the white noise helps to reduce the inhibition of neurons that impairs the ability to filter irrelevant information. However, according to scientists, it is necessary to confirm this in the new experiments involving humans.
