iPods make Ear buzzing

Music is one way to improve morale, music makes life more vivid, but what if the music makes the ears buzzing? Certainly not music that makes ears buzzing, 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 iPods users experiencing hearing loss. Users of portable music players are often at risk of increased ear buzzing (tinnitus) or other hearing problems, this trend more prevalent on the max volume of users iPods.

National Acoustic Laboratories in Sydney asked the respondents listened to music with a volume comparable with 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 normal habits of their ears.

The study recorded approximately 25 percent of respondents tend to listen to iPods or other portable music in the capacity of 'noisy' is proportional to the noise level of 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 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 audiagram 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 around 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.
