Loud music played on earphones causes deafness by having a similar effect on nerves as multiple sclerosis (MS), scientists have learned.
New 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.
Loud noises are well known to lead to hearing problems such as temporary deafness or tinnitus (ringing in the ears). But this is the first time scientists have been able to identify the underlying …show more content…
(Music with English lyrics can be so distracting that "I'll have a tendency to sing along.") She plays louder, faster music in the morning to help her wake up, and softer, classical tunes when she needs to concentrate on a proposal.

Employees at PageSoutherlandPage are free to do "whatever aids productivity," says Kurt Neubek, associate principal. While the company's open-office plan aids collaboration, "everybody needs heads-down time, and putting on headphones is an easy way to do that."
Patrick Ramsey, 24, a software engineer at Name.com, a Denver-based Internet domain-name registry and Web-hosting company, also listens mostly to instrumental music on ear buds, but only when he is writing code. Music interferes when he tries to write email or document summaries, but its "repetitive beat" helps him with the logical, step-by-step process of programming, he says.
He focuses so deeply that he almost jumped out of his skin when his boss, Bill Mushkin, tapped his shoulder recently while he was tuned into his favorite jazz-reggae group, Thievery …show more content…
Adults aged 18 to 30 were asked to recall a series of sounds presented in a particular order. Participants’ performance suffered when music was played while they carried out the task as compared to when they completed the task in a quiet environment. Nick Perham, the British researcher who conducted the study, notes that playing music you like can lift your mood and increase your arousal — if you listen to it before getting down to work. But it serves as a distraction from cognitively demanding
