Earphone noise effect on nerves similar to MS

Loud music played on earphones causes deafness by having a similar effect on nerves as multiple sclerosis (MS), scientists have learned.

Research shows that noise levels above 110 decibels strip insulation from nerve fibres carrying signals from the ear to the brain. Loss of the protective coating, called myelin, disrupts electrical nerve signals.

The same process, this time due to an attack from the immune system, damages nerves in the brain and results in MS.
