With the advancement of scientific discoveries and the multiplicity of Menahiha, markets offer us more and more luxury devices to secure additional doses of the thrill of well-being are looking for a man these days.

And control of AIDS patients who are dying slowly give you an idea of the product of the theories of modern education and emancipation.
And what we want to talk about today is the portable music devices.
Contemplates our young people - and even children - Photos youth and children in the West movies they put portable music devices on their ears, Vtthrk them an inferiority complex which we are suffering towards the West, part, believe that happiness will come through these devices.
Their families are demanding those devices, and take to the market to see a tremendous amount, and many types of these devices, becoming more and more appetite and salivate and Aharon Aharon and even find the Bgathm.
Teenager back to his house, put headphones on his ears device, isolated from the ocean around a wall of noise, and the case will continue on those hours and hours.
But if we put aside distractibility and neglect the academic and intellectual stagnation, is for those devices other adverse effects?
Yes, it is the effects on hearing and disposed of by the doctors states that have preceded us in the use of these devices and began to reap results in the form of lack of hearing with ringing in the ears, so that one of the doctors found a lot of young eighteen its year is almost hearing about the weakness heard the sons of sixty and seventy Age.
The beginning was with the advent of devices WALKMANN in 1980, then appeared devices portable CD (CD-ROM) has called for doctors to draw up laws governing majority wrenches that can give these devices, in addition to determining the intensity acoustic concerts in public places. Several laws have been issued in this regard in a number of European countries.
But the advent of MP3 devices returned the case to the arena, it has properties harmful to hearing more from the previous (wrenches higher, the time to listen longer, batteries can be used for a long time), especially with the advent of headsets that can be introduced in the course of the hearing, which lead to increased intensity sound within the ear (increase in sound intensity inside by 6-9 dB, compared with speakers that are placed on the pinna).
Young men and women who love loud music, which paralyzes thinking and allow isolation and make the body in the event of vibration proportional to the intensity of the sound (they love rap and rock more than classical music or jazz)
The acoustic intensity given by these devices may reach 110-120 decibels, which is equivalent to the intensity that can be heard (maximum) at rock concerts, and this is enough to cause damage sensory nerve after 75 minutes of exposure to these sounds.
How we come across in daily practice youthful young people seem to ringing in the ear or two after attending a noisy party (Disco, Rock, .......)
French law, for example, the campus marketing portable music devices that give the intensity of up to 100 dB, but young people know very well how to change some of the pieces to get to the highest intensities (As we say that the mind stops in front of the Sultan fancy). It is recommended to reduce injuries audio for these devices to resort to:
- Base 60% - 60 minutes: Do not use the machine more than an hour a day strongly not to exceed 60% of the magnitude of the Great (Example: If the maximum gradient up to ten degrees must not exceed 6)
- The use of headphones are placed on the ear flap and not inside the sinkhole: knowing that the higher cost, and may not be typical aesthetically pleasing, but the companies are seeking to secure the aesthetic requirements appropriate for young people.
As we can see, this issue needs to address the media draws children of young men and women before they weaken the opportunity to maintain a normal serving heard for years longer.
