Turn down your iPod or risk an ear tumour

(Daily Mail Via Thomson Dialog NewsEdge)LISTENING to loud music on a personal music player such as an iPod can trigger tumours that lead to deafness, it emerged yesterday.

Researchers said repeated exposure to excessive noise can increase the risk of developing acoustic neuroma.

This is a non-cancerous tumour which can cause hearing damage by pressing on crucial nerves.

Experts from Ohio State University studied 146 acoustic neuroma sufferers and 564 men and women without the condition.

The research involved looking at the levels of noise to which the volunteers were regularly exposed.

For the purposes of the study, any sound over 80 decibels - the level of city traffic - was classified as loud.

Personal music players have a maximum volume of 104 decibels - more than 20 per cent higher. The researchers concluded that exposure to loud music doubled the chance of getting a tumour.

The study, published in the American Journal of Epidemiology, did not look at how volunteers were exposed to loud music, whether at concerts, through normal hi-fi speakers or headphones.

But only last week Who guitarist Pete Townshend blamed his own hearing loss on years of wearing studio headphones.

It is not the first time that experts have issued warnings about the dangers of listening to music too loudly on MP3 players, such as Apple's massively popular iPod.

The Royal National Institute for Deaf People found 39 per cent of 18 to 24-year-olds admitted listening to an MP3 for at least one hour a day.

Angela King, senior audiologist at the institute, said: 'There is a danger that long-term use of personal music players at high volume will permanently damage people's hearing.' The charity's Don't Lose The Music Campaign advises MP3 users to take regular breaks from listening, and to turn the volume down a notch from their normal level.
