Hear is something totally different to listen to. Listening means hearing without the mind; listening means hearing without any interference of your thoughts; listening means hearing as if you were completely empty. If you have even a small vibration of thought inwardly, waves of subtle thoughts around you, you will notbe able to hear. And to listen to the music, ancient music, the eternal music, one needs to be completely quiet; It is as if one were not. When you are, you can hear; "when you're not, you can listen to."

Abstract Of all human senses the ear is one of the most sensitive. It allows us to perceive a wide range of sounds as well as enjoy abeautiful melody. This system, which seems to be very simple, is in fact a very complex system involving accurate bio-mechanical operations. Do we really know how the auditory mechanism works? Do we take proper care and pay enough attention to this sensitive organ which accompanies us in our daily activities? This paper aims to raise awareness about the appropriate use of the auditory system and thehazards of exposing it to intense or violent sounds. As educators, we want to warn young people about the hazards of listening to music too loudly on a permanent basis. Using headphones as well as being exposed to excessive sound volumes at discos can produce permanent damage to the ear. Audition loss when coming out of discos and bewilderment due to excessive volume at the gym and amusement sites aresome of the effects of loud music. This work is an attempt to model the human ear and carry out some sound experiences to analyze how we actually hear and the damage that excessive volume can cause us.

1. - Introduction In our daily activities we use our senses to communicate and interpret the messages from our environment. Our auditory system is all the time receiving a wide range of soundstimuli. The intensity of the sound we perceive alters our behavior and, in many cases, it can cause deafness or bewilderment. How does the auditory mechanism work? Our auditory system consists of a set of bio-mechanical elements that function individually but, at the same time, produce a final synergy which results in a system capable of perceiving the widest range of sounds from our environment.Furthermore, when we go on holiday to a place away from big cities, we say we can “hear” the silence of the mountains or the country side. It most probably may have happened to you that during the day you do not perceive certain sounds covered by the murmur in the environment. But at night, when the outside noise is quieted, we can hear the clock´s tic-tac or the furniture creak when temperaturegoes down. Noise is part of the surrounding nature, even in deserts or desolate places there are a considerable number of noises which have existed even many years before human beings originated on earth. Noises produced by thunder, volcanic eruptions, earth movements and sounds uttered by gigantic animals were very common in ancient times. Some of these have now been replaced by those produced byhuman beings, supersonic planes, pneumatic hammers, different kinds of equipment, etc. 2. Operation of the auditory system Our auditory system starts in the ear, which functions as a “parabolic antenna” capturing and concentrating the environment sounds. These vibrations enter the auditory pavilion, go along the auditory canal and stimulate the membrane at the end of it, called “tympanic...
