The reason for the warning is because earbuds placed directly into the ear, can boost the sound signal by as much as six to nine decibels.
As well as a more intense sound signal, today's music devices have longer battery life and the ability to store vast amounts of music, facts which encourage users to listen for longer periods of time than their 1980s counterparts.
MP3 devices now reach upto 110 to 120 decibels. That's a sound level that's equivalent to a jet engine and enough to cause hearing loss after only about an hour and 15 minutes.
So what can we do? One solution is the 60 percent/60 minute rule, whereby people use their MP3 devices for no more than about an hour a day and at levels below 60 percent of maximum volume.
Noise-cancelling headphones are another suggestion because they reduce or eliminate background noise eliminating the need to turn the device up to excessive levels.These headphones can be custom made; still as descreet as the fashionable ear-bud types and far more comfortable.
They come as a sleeve which fits over any ear-bud headphone, so even if the headphones need replacing the sleeve can simply be swapped over. At less than £100 they could be the last set of headphones you ever use.
