Researchers found one in ten people regularly turn their radio up to a higher volume than a drill on a building site, with another one in six listening to their MP3 player at deafening levels.
One in twenty regularly plug into their music which is more thunderous than a train hurtling past in a station or a car alarm ringing in your ears.
And worryingly, 17 per cent have been left with ringing ears after listening to blaring music for a long period of time.
At least that's what we think the researchers were saying, we couldn't hear they all that well.
The study also found a quarter of people turn off their 'volume limiter' and one in twenty listen to music at its highest volume level.
Worryingly, nine in ten said they didn't know what the safe level of sound was for their ears. One in twenty also said their music is often noisier than road works, or a car back-firing.

A spokesperson for The Hearing Company, which polled 2,000 Brits on their music listening habits to mark National Deafness Week, said: "These results prove that most Brits are blissfully unaware how a simple everyday pleasure of listening to music can actually be harmful to their hearing.
"Damage begins when ears are exposed to noises louder than 85 decibels for prolonged periods of time. A pneumatic drill, for example, reaches 110 decibels, which means that millions of Brits are listening to their music at a level of almost 40% higher than is naturally safe. A shocking statistic.
