EARS
Sound is important for communication and it is also a key to personal safety in situations where a noise can warn us to approaching danger. Most of us take our hearing in stride and probably don't appreciate what we have been given until it is taken away. The ability to hear can be lost in an instant with a loud explosion, a foolish prank played with an airhorn, or standing too close to very loud speakers at a concert. The abuse our ears take slowly reduces their sensitivity, and we all become slightly more deaf as the years pass. We can, however, slow that negative progression and retain our good hearing well into old age, if we take just a few precautions, and provided we don't have an inherited hearing problem.
We all know that loud noise can damage our hearing - but not enuough noise can also impair it. It can be - if the music is too loud. It sit closer to the eardrum, so it create more sound pressure that traditional earphones, increasing the risk of damage. If you hear ringing in your ears or if things sound muffled after listening, you're likely overdone it. Usually the problem subsides, but listening to lound music regularly, with any types of headset, could lead to permanent hearing loss. Any type of headphone has the potential to cause [noise-induced hearing loss] if used improperly in terms of absolute level of the sounds, the length of exposure time to sound, and the fit of the earphones or headphones.
Loud rock music contributed to hearing loss among baby boomers, but MP3 players are poised to make the problem much worse for the next generation. These devices, which pump music through earphones directly into the ear canal, enable the user to overcome the rumble of the subway or the drone of an airplane engine without drawing angry shouts of "turn it down!As a result, they easily desensitize the user to dangerously high sound levels. A CD player and a Walkman do too, but MP3 players such as the iPod pose an additional danger. Because they hold thousands of songs and can play for hours without recharging, users tend to listen continuously for hours at a time. They don't even have to stop to change a CD or a tape. Longer Listening, More Damage. Since damage to hearing caused by high volume is determined by its duration, continuous listening to an MP3 player, even at a seemingly reasonable level, can damage the delicate hair cells in the inner ear that transmit sound impulses to the brain. Every time you increase a sound level by three decibels, listening for half as long will produce the same amount of hearing loss. Most of the guys probably listens for several hours a day, placing a large noise burden on his hearing even if turns it down when not cutting grass. Now, anywhere we can simply found the people hearing the music with earphone [of course including me] hehehe!!!!I love music too but what we can do is trying to reduce it. It really affect our hearing.
