Children have always loved to listen to your favorite music, and the louder the better - many of their parents' disappointment. In 1980, a portable tape recorder with headphones - which came to be known as the "Walkman" -. Enabled teenagers to listen to your music as loud as they wanted, anywhere they wanted, without disturbing anyone around them
, but there is a modern interpretation of the Walkman - the portable MP3 players and iPods -. Pose a great threat to our hearing health of children, and our
the problem is a combination of technology, portable digital devices that creates a non-buffered crystal clear sound, and the type of headphones typically used with them, without any buffer. In December 2005, Dean Garstecki, an audiologist and professor at Northwestern University reported that more and more young people have been diagnosed with a type of hearing loss typically found in older adults. He attributed this trend to "pad" headphones that usually accompany an iPod or MP3 player. With headphones, the sound frequencies are not buffered as they are with more traditional, ear cup style headphones.
Newsweek Magazine recently reported that scientists at the House Ear Institute found that listeners, unfortunately, can increase the capacity of today's portable digital devices without the "distortion that occurs with traditional analog audio." Older model headphones that were popular only 15-20 years ago - that have ear cups outside the ears - had that distortion when the volume was turned up, which acted as a necessary buffer to protect our hearing. Today's technology does not provide that buffer - the headset in your ear, not outside, and digital devices that do not create distortions, no matter how high the volume
.In addition, people often listen to these devices, while on the go, and tend to crank the volume in an attempt to drown out outside noise, which further risk to our discussion. The use of headphones during activities such as exercise, for example, puts the user at greater risk. During exercise, the blood, which can act as a buffer, is diverted from the ears to other parts of the body -. So our already vulnerable hearing is in danger even
Headwize reports that a study conducted on music listeners using headphones revealed that while indoors without background noise, the participants were satisfied with their music at 69 decibels. Outdoors, where background noise was recorded at 65 decibels, participants using their headphones turned the volume up to 82 decibels and as high as 95 decibels to drown out the surrounding buke.Zaštiti Work Administration guidelines limit exposure to noise at this level no more than four hours each day. The study concluded that participants were at risk for hearing damage and recommended "avoiding continuous use of [portable stereo] in noisy conditions ."
Northwestern University's Dean Garstecki offers more specific guidance: - ". About an hour a day and at levels below 60 percent of maximum volume," his 60-minute rule percent/60 listen to MP3 players and iPods zaProblem is, most people using headsets - young music fans - listen to your music for much longer than one hour. No, you can help minimize hearing loss, damage and problems while listening to your favorite music as much as you want to -. The secret is in the handset
headphones, such as the EX29 Extreme Isolation Noise Reduction Headphones help block out external noise allow you to hear the fine details of your music without blowing bubnjevi.Uho ear cup fits over the ear, not in it, and the headphones are lightweight, does not require batteries and can be used with your MP3 player or iPod. With 29 decibels of isolation from outside sound, headphones quiet block outside noise and there is no need to handle the volume of music.
Aging rock stars like the Who's Pete Townsend, who has some permanent hearing loss from years of exposure to loud music, and Mick Fleetwood, who has teamed up with Energizer batteries to promote hearing loss prevention, have brought public attention to many of načinjenica We take for granted our hearing. However, there is no need to exclude your music - just be smarter about how to listen. If you use an MP3 player or iPod when you exercise, the environment or just want to hear the fine details of your music, ditch the headphones and turn to a set of noise reduction ones instead. And you'll be enjoying your favorite music for a long time to come.
