Create iPods Ear buzzing

Music morale-booster one way, music makes life more vivid, but what would happen if the music makes the ears buzzing? Certainly not music that makes the ears 'ngungung', but the behavior we listen to music that makes hearing so there's no longer sharp.
Researchers in Australia found that approximately a quarter of users iPods have a hearing loss. iPods mania or other users of portable music players are often at risk of increased ear buzzing (tinnitus) or other hearing problems, this trend more prevalent on iPods user plays the outrageous volume of his iPods.
National Acoustic Laboratories in Sydney asked the respondents listen to music with volume proportional to the motor-engine devices (ie: drilling machine). The researchers found that the level of buzzing (tinnitus) will increase because the hearing could no longer adopt the habits of their ears normal.
The study recorded approximately 25 percent of respondents tend to listen to iPods or other portable music in the capacity of 'noise' noise level comparable with the voices on a lawn mower or motor powered device, with an average intensity above 85 decibels.
In its normal size, a person with normal hearing his audiogram lies between 0 to 20 decibels, more than 30 decibels with a range of up to 100 decibels means that there is a hearing loss.
Measuring the intensity of normal hearing is recorded in the form of audiogram, where audigram which lies between 30 to 40 decibels, including mild disturbances. From 40 to 60 decibels, including medium scale. Between 60 to 90 decibels has been heavy. As an illustration, the sound of the streets the same drilling machine with 100 decibels. Aircraft engine 120 decibels. A quiet room was roughly about 30 to 40 decibels.
"Enjoy the disco music, attend a dance, working in factories, listening to music while driving or just listening to music in the room, regardless of its condition if disturbing the ears, it has been categorized as 'noise'," said Professor Harvey Dillon, the originator of the research.
"It is better to listen to music in the normal frequency, this disorder may not appear in the near future but did not close the possibility of triggering a more severe disruption next few years," added Prof. Dillon.
