www.healthydailymail.com Doctors Health - listening habits portable music player (PMP), such as MP3 players, can make ear injury. That happens if we too often wear earphones or headphones high volume. Based on the study, adverse effects come when using earphones for five hours in a week. The impact is permanent damage to the ear, most likely it happens at a young age.
Currently effects may not be seen, but one day it will feel. Listening to personal music players regularly in high volumes when young often has no impact on the hearing. However, later listening skills can disappear, obviously one of the researchers at the International Herald Tribune.

The statement was given nine researchers from the Committee on Emerging and Newly Identified Risks celebration. In fact, they also stated that the risk of hearing loss will be obtained in the mid 20s. However, listening to music via portable media also cause other effects. Music can isolate the listener from the general public. When driving, the music can increase the risk of hearing loss on the situation sekitar.Penyebab hearing loss are diverse.
Also depends on the person's age. Sound is divided into several levels. Light sound for adults is between 25 to 40 dB, while for children 20 to 40 dB. -Rise higher up the heaviest sound quality of 90 dB or more which still can be heard humans.
Electricity electromagnetic waves affect the brain, but the question is how much influence these waves against brain damage? until now there has been no single strong medical evidence to prove it. Although electromagnetic waves affect the brain of mice, but not proven in human brain Until now several European studies on electromagnetic waves against brain tumors can not prove tersebut.Mengenai effects influence to ear, exposure to music with earphones can affect the threshold of hearing, especially when done at high volume and long term.
Some ways to reduce the damage to hearing is to reduce the volume and reduce the time to listen with earphones. But too often people use earphones in crowded places such as train stations, bus terminals, etc., would involuntarily tend to increase the volume of the earphones even harder.
Some suggestions to reduce side effects such as using headphones are great (old type), so the sound is more distributed and more closed than the noise from outside the small earphones. Type tiny earbuds have small speakers with large volume placed in the ear hole is definitely a greater effect on hearing compared with headphones that only affixed to the outer ear.
Following the negative effects of a headset or earphones for your health:
1. Permanent damage to the ear
This occurs when the ear is not strong anymore burden loud sound from the earphones that directly connects with the ear canal, usually, this happens to those who are young or adolescent.2. Loss of hearing in the 20s
Based on the study, the effects of the use of earphones or headsets that this excess is not immediate. Damage caused by the use of a headset or earphones excess will appear slowly, usually the effect will not be felt in the 20s. At that age, the patient will begin to lose his hearing.
3. Damage to the brain
Electromagnetic waves due to the earphone or headset is supposed to influence the brain's electrical. Evidently this elektromagnetig wave effect on electrical brain in rats. However, until now not known how much of the effect of the electromagnetic waves on the human brain. But clearly you have to remain vigilant.
4. Threshold of hearing
Exposure to music with earphones or headsets may affect the threshold of human hearing, especially when done with loud volume and in the long term. Gradually this effect will lead to permanent hearing loss.
Therefore you must use earphones or headsets as needed, do not be excessive. Regarding the level of sound, sound light level for an adult is between 25 and 40 decibels, while children 20 to 40 decibels. -Rise higher up the heaviest sound quality of 90 decibels or more can still be heard.
Some researchers recommend that all devices that use a headset or earphones to not exceed the limit of 100 decibels. Given that no outside sound headset (car engine noise, diesel or mower) can also affect the human hearing.
