The amount of energy in the noise and the damage it can do to your hearing increases very rapidly as it gets louder. In fact, noise energy doubles for every 3 decibels (3dB) increase in the loudness of the sound - and 3dB is such a small increase in loudness that you probably wouldn't even notice it.

What sort of noise causes the harm? For young people in particular, the most dangerous noise is amplified music, for example in gigs and clubs. Headphones, car stereos and mobile phones are also having a bad effect on the hearing of young people.

One study suggests that listening to headphones at 80% for 90 minutes a day can lead to hearing loss. The authors say that this can take years for the damage to show up, so young people might not notice a loss of hearing until they are in their late 20s. At 100% for only five minutes you could do damage.

The study, by researchers at the University of Colorado at Boulder and Children's Hospital in Boston, indicates a typical person can safely listen to an iPod for 4.6 hours per day at 70 percent volume using stock earphones, according to Cory Portnuff, a doctoral researcher in CU-Boulder's speech language and hearing sciences department.

Typical individuals can tolerate about two hours a day of a decibel unit known as 91-dBA before risking hearing loss, Portnuff said. The term dBA stands for "A-weighted decibels, a scale that takes into account that the human ear has different sensitivities to different frequency levels,"

Loud sounds can stress and potentially damage delicate hair cells in the inner ear that convert mechanical vibrations, or sound, to electrical signals that the brain interprets as sound. "Over time, the hair cells can become permanently damaged and no longer work

No one set of earphones is more dangerous than another," he said. "While isolator style earphones are capable of producing higher levels of sound than earbuds, most people use them at a lower volume than earbuds because they block out background noise. It's important to monitor the level of volume control settings."
