WHAT !.... yes, i have it..
did you know...Lars Ulrich/Metallica:
“Three of the four members of Metallica wear earplugs. Some people think earplugs are for wimps. But if you don’t want to hear any records in five or ten years, that’s your decision.”
andWatch your hearing!
Your ears are very delicate, prolonged exposure to sound pressure levels above 85dBA will cause damage to your hearing. If you have ever been to a party or to a concert where loud music was played, you may have experienced Temporary Threshold Shift (TTS). This temporary loss of hearing can become permanent if exposure is done on a regular basis. If this happens, you will never hear fully again. The only real solution then would be to be fitted for a hearing aid - not an attractive prospect for anyone, especially a teenager.
One way to tell if you’ve been exposed to excessive sound pressure levels is that you tend to hear a ringing in your ears.
Ringing in your ears, hissing, clicking or buzzing sounds all represent the effects of tinnitus, which is often a side effect of noise-induced hearing loss. Inner-ear cells are sensitive to vibrations. But if they’re damaged, the ears will still record ringing or buzzing, even when there’s no sound.
Remember, it is your high frequency hearing that deteriorates first. Think of what music would sound like if you couldn’t hear anything above 10KHz: just like with a crummy old transistor radio or listening to music over a telephone (no cymbals or high pitched instruments, voices sounding deadened). Protect yourself or just turn it down!
The high frequencies are lost first, so you may have difficulty hearing high-pitched voices. Loss of high-frequency hearing makes many words sound alike, especially those containing the high-frequency sounds S or soft C, F, SH, CH or H. Words like “hill,” “fill” and “sill” may sound exactly the same.
headphones, ear-pieces and “ear bud” phones
as often used, loud ipods and mp3 players damage hearing
“The big culprits aren't the devices themselves [iPods and MP3 players], but the tiny "ear bud'' style headphones that the music players use.”
“the earbuds are even more likely to cause hearing loss than the muff-type earphones that were used on Walkman and portable CD players”
“on average, the smaller [the headphones] were, the higher their output levels at any given volume-control setting.” [Harvard Medical School study]
“tiny phones inserted into the ears are not as efficient at blocking outside sounds as the cushioned headsets, users tend to crank up the volume to compensate.”
“a quarter of iPod users between 18 and 54 years of age listened at volumes sufficient to cause hearing damage.” [Australian research]
As one researcher found was often the case, listening to music/muzak at 110 to 120 decibels damages hearing in less than an hour and a half. Thus, the “longer-lasting batteries and more storage capacity encourages people with portable players to listen longer, not giving the ears a chance to recover”.
Pete Townshend on iPods“Who guitarist Pete Townshend is warning iPod users they may face hearing loss if they pump up the volume on the devices.
“Townshend, 60, said his hearing was irreversibly damaged from using studio headphones, and he now takes 36-hour breaks between recording sessions. The band was known for loud performances.
“ "Hearing loss is a terrible thing because it cannot be repaired," Townshend said on his website. "If you use an iPod or anything like it, or your child uses one, you may be OK. (...) But my intuition tells me there is terrible trouble ahead." ”
“[...] a typical person can safely listen to an iPod for 4.6 hours per day at 70 per cent volume using stock earphones, said Cory Portnuff, a doctoral researcher at the University of Colorado, Boulder and co-author of the study.
“ "Damage to hearing occurs when a person is exposed to loud sounds over time," he said Thursday. "The risk of hearing loss increases as sound is played louder and louder for long durations, so knowing the levels one is listening to music at, and for how long, is extremely important." ” [Quoted from cbc.ca]
