2. What consequences
APPROACH leads us to bring our musca?, No matter how dramatic you hear the famous headphones that come with our media players, we usually bring the highest
volume without considering the consequences that this brings, knowing that we are may result from a temporary hearing damage, even permanent deafness.
We suggest, that the problem is related to young people who like loud music, being that they are the most cutting edge in technology issues, however, that there ear headphones reduce these risks, but do not lose the level of damage, today, bring a headset is like bringing a sweater, because every time are even cheaper, low quality, which bring us an early generation of the deaf, both temporary and permanent .
3. JUSTIFICATION
"Listening to music on these devices with a high volume may cause trauma in the perception of high tones of the ear. At first only be a temporary injury (lasted a few hours), but over time the average frequency would also be lowered, which would end in a significant reduction in hearing ability, "said Edgar Chiossone Lares, a specialist ENT Medical Group.
Apart from being a final draft of the semester for which we investigate, we do not remove the interest to find this information, since in the long term, we're going to be the most affected, and why not take matters into it right now is time?, if we still have. Technology has driven us to the point where people can use headphones that are capable of neutralizing the noise from the environment, which would work to not be forced to raise the volume of the player, the human ear is made to listen These appliances are not hurt if the damage is caused by the misuse.

4. OBJECTIVES
distribute this issue of hearing loss among the student community
distribute information among the community of CECYTA, to make a personal analysis of the damage it causes to enjoy their music at volumes loud.
5. BACKGROUND AND DEVELOPMENT OF THE PROBLEM.
According to Social Security numbers in our country 27 percent of the population suffers some deterioration in the ears, temporary opermanente, a figure that could triple in coming years. People who undergo these faced extreme noise damage, premature in their auditory system, although after 50 years people face gradually lost his hearing in a natural way, the problem is accelerating who have worked or have been exposed to loud noise, in which case the damages are often more severe.
The effects on the auditory system are irreversible. While it can help people to recover part of its capacity with some appliances, but this benefit is not very high. Today
is developing a generation that in the future, people with serious hearing problems, this problem is compounded by the globalization of technologies and social holdings leading to the teenager in this case, listen to your music loud volumes.
This factor has been aggravated not just teenagers, but even in children, therefore globalization, it is easier to acquire various music players, although the price is affordable, even cheap, we realize the damage are buying when you purchase this device with the quality of your headphones, we know that damage to the population is high, and statistics focus on different points, but in this research, we try only to adolescents specifically.
6. THEORETICAL
The auditory system may suffer severe and irreversible damage laexposición constant and prolonged loud noises, cuestioneslaborales both as fun, as is the use of audio devices seregalan children, who use them with headphones and a high volume to hear them.
townsman plunged into chaos in the midst of the cry of a driver in traffic, the roar of a broken exhaust and stormy sound of the horn of a micro, a passer-by can still hear his song your favorite digital player, despite the heterogeneous mixture of sounds, perhaps at that moment will not notice the difference, but will do so in a few years.
http://alexgrod.blog.com/2796435/ The hearing
not only decreases with age, but also with the permanent exhibition to very loud noises, which could permanently damage the ear. Digital music players (such as ellpod or Mp3 player), if not kept at the proper intensity and listen for short periods, may be responsible for the gradual loss of hearing.
According to the Department of Otolaryngology at the University of Michigan, music players can reach 110 decibels (if placed at maximum volume), so it could enter the classification of those who disrupt the hearing, when listening to music with these devices in the street external noise forcing people to turn up the volume to maximum to hear effectively. Here the problems begin.

-*- Sound: any phenomenon that involves the propagation of elastic waves in a nearly audible or inaudible, usually through a fluid (or other elastic medium) that generate vibration of a body. The sound is humanly audible sound waves consist of oscillations of air pressure, which are converted into mechanical waves in the human ear and perceived by the brain. Sound propagation is similar in fluids, where the sound takes the form of pressure fluctuations. In the solid sound propagation involves variations of the stress state of the environment. -*-
Decibel is equivalent to a tenth of a bel. Reference unit for measuring power of a signal intensity of a sound. The name comes from the American physicist bel Alexander Graham Bell.
http://es.wikipedia.org/wiki/Decibel -*- Volume: subjective perception that human beings have the power of a particular sound. As the intensity of a sound determines the amount of energy (acoustic power) flowing through a surface per second, at high power and therefore mayor volumen. Sin embargo, no hay que confundir volumen, con sonoridad, que es la percepción subjetiva de la intensidad. Como la percepción del volumen sigue una escala logarítmica, el nivel de volumen se mide en decibelios y viene dado por el denominado nivel de potencia acústica.

-*-Ruido: En el medio ambiente se define como ruido todo sonido no deseado por el receptor.
http://es.wikipedia.org/wiki/Ruido -*-Globalización: es un proceso fundamentalmente económico que consiste en la creciente integración de las distintas economías nacionales en una única economía de mercado mundial. Su definición and assessment may vary depending on the interlocutor.
9. DESIGN OF FIELD WORK AND / OR FILE AND METHODOLOGY
will obtain references from different sources of information such as the internet, magazines, newspapers, encyclopedias, radio and television programs. Another option is to consult both Physical and otolaryngologists to bring to trial different approaches and agree on best results.
10. PARTIAL AND FINAL PRODUCT IS INTENDED TO ACHIEVE
. Disseminating damage qenera listening to music on those levels. and so on. qenerar trying awareness through posters and brochures.
inform young people different today tecnoloqías
exist to reduce the damage that occurs, hence the creation of this blog
