One billion young at risk of hearing loss from loud music: WHO
GENEVA - More than one billion young people risk damaging their hearing through listening to loud music, the World Health Organization (WHO) said on Friday.
The WHO estimates that around half of those between the ages of 12 and 35 in middle- and high-income countries are at risk due to unsafe levels of sound on personal audio devices or smartphones.
Another 40 percent are at risk from damaging audio levels at concert venues and night clubs.
"More and more young people are exposed to unsafe levels of sounds. Young people should be aware that once you lose your hearing, it won't come back," said Shelley Chadha, a WHO specialist on hearing impairment.
The UN health agency considers a volume above 85 decibels for eight hours or 100 decibels for 15 minutes as unsafe.
Exposure to traffic noise at peak hours can reach 85 decibels.
The vuvuzela, a popular wind instrument used in stadiums during the football World Cup in South Africa in 2010, has a sound intensity of 120 decibels and over nine seconds of exposure could result in irreversible hearing damage.
"It is something we can live without," Chadha said referring to the vuvuzela.
To counter the risks, the WHO recommends that personal audio devices should not be used for more than an hour a day, at reduced sound levels.
The use of ear plugs in loud conditions and regular check ups were part of the recommendations as well.
The WHO also wants governments to play a role by imposing strict regulations on noise in public places.
The UN agency estimates that 360 million people suffer from hearing loss worldwide. In addition to noise related causes and ageing, it is also brought on by infectious diseases, genetic conditions, complications at birth, and use of certain drugs.

Music lovers seek to pump up digital audio quality
WASHINGTON — When he sees people listening to music on portable digital devices, David Chesky cringes.
“You can have an $8 million Stradivarius, and it sounds like you bought it at a local hardware store,” says Chesky.
A composer who also has his own record label, Chesky began a music download site in 2007 called HD Tracks, offering “high resolution” music which retains much of the fidelity lost in most digital music.
“We are making a quality product for someone who is passionate about music,” Chesky told AFP.
“No artist goes into a studio and slaves for six months over each detail, to have their music listened to on a laptop and $5 headsets.”
Chesky’s was among the first offering high-res digital music which captures more quality than typical MP3 audio files, but the segment is growing, with music labels, electronics firms, musicians and others joining the push for better-quality formats.
Increased broadband speeds are another factor, allowing high-quality music downloads without the compression that many say is detrimental to sound quality.
High-res market grows
Jared Sacks, an American living in the Netherlands who is preparing an expanded launch of a site called nativedsd.com, said he believes the market is evolving.
Sacks said many consumers under the age of 35 have never heard high-quality audio, and “now some people are waking up and saying ‘we want this quality.’”
The outlook is brighter, Sacks said, because of the availability of hardware, download sites like his and lower-cost digital storage and Internet access.
“A year and a half ago you had only two (high-resolution audio) players and now there are over 60,” he said.
“People who want good quality are willing to pay for it, but a lot of people have never heard better quality.”
Sacks’s site and HD Tracks are among six partnering with Sony, selling high-resolution audio files which can be played on the Japanese firm’s recently launched HD audio equipment.
HD audio will cost more than what most consumers are paying, but many audiophiles appear willing to pay roughly $20 to $30 for an music album, and individual tracks close to $3.
“I think the digital stars are aligning,” says Jeffrey Joseph, senior vice president at the Consumer Electronics Association, a trade group for the tech industry.
“Our research indicates the market for high quality music products is extending beyond the enthusiasts.”
Joseph said debate over music quality has been around for decades, with the advent of the CD, which “lacked the warmth” of vinyl recordings. Digital technology allowed music to reach more people, but often sacrificed quality.
“What is particularly exciting about high resolution is that it has the high quality sound that you want but all the benefits of digital — the portability, the customization,” he said.
On display at CES
At the CEA’s annual International Consumer Electronics Show in January, a space will be dedicated for the first time to high-resolution music. CEA said its survey found 39 percent of consumers with a moderate interest in audio indicate they are willing to pay more for high quality audio electronics devices and 60 percent would pay more for higher quality digital music.
Sony has joined the effort both as a music publisher — by making its recordings available in high-definition format — and as an electronics maker with a range of high-resolution audio devices including music players, headphones and speakers.
“What the consumer needed was products that supported everything they could get their hands on” fore higher-quality digital music, Sony Electronics product manager Aaron Levine told AFP.
Sony maintains that high resolution audio helps recreate the experience of an original studio recording or live performance.
After home audio, the next frontier for high-resolution is portable. Sony has been selling a portable HD player in some markets, and South Korea’s Astell & Kern has devices selling at $700 to $1,300 which promise HD sound.
But some music lovers are waiting for a device being developed by pop star Neil Young, who is promising a portable player in early 2014 called Pono.
“Miraculously, there’s a wealth of music & soul (or if you must, ‘data’) trapped on millions of recordings made over the last half century, that we’re hoping to unleash for the very first time,” Young said in a Facebook post.
“We’re still toiling away on making this happen.”
Do listeners care?
Some experts say new formats are unlikely to take hold because most consumers cannot tell the difference.
“I hate to use the term ‘snob appeal’ but that’s really what it is,” said Colby Leider, director of music engineer at the University of Miami’s Frost School of Music.
Leider, who has studied both electrical engineering and music composition, said while it is true much data is lost when music is compressed to the MP3 format, “it works because it removes the portions of sound that most humans can’t hear.”
“There are people who buy a $20,000 power cable to plug it into their system. But science says there is no difference between your $20,000 power cable and a coat hanger.”
Digital music on CDs is based on a “sampling” at 44,1000 times a second, transferring 16 bits; MP3 music has less data, and HD is higher, often sampling at 96,000 times a second with 24 or 32 bits of data.
“Some people can tell the difference,” Leider said. “But if it’s a great song, you are still going to love it even if it’s not HD, and if it’s a bad song, it doesn’t matter.”

Plantronics unveils latest Bluetooth headsets
MANILA, Philippines — In 1969, American audio communications brand Plantronics provided the headset Neil Armstrong spoke through while taking man’s first steps on the moon.
More than 40 years down the road and the company continues to innovate on ways to make communicating simpler, yet smarter for mobile executives, road warriors, and smartphone users.
The Voyager Legend headset and the Marque 2 M165 headset, for example, are upgrades of previous versions: the Voyager Pro HD and Marque 1, respectively, and both models were unveiled on Tuesday at Ascott Makati.
The Voyager Legend is a sleek black device with a slim, silver multi-microphone that reduces wind, movement, and background noise by up to 70 percent, which enhances the user’s voice as well. Talk time with this unit is pegged up to seven hours.
The 18-gram gadget operates on voice commands, with the user able to answer a call by saying, “Answer,” or reject a call by saying, “Ignore.” More commands can be found by asking, “What can I say?” The Voyager Legend will also tell you who is on the line.
It is a “highly intelligent device,” said Plantronics senior country manager Josh Doctolero.
“If you are paired with a smartphone and you put the device on your ear, the device acknowledges that it is on your ear. When you remove it, and you have an incoming call, you have the option to wear it. You don’t have to press anything, just say “Answer” or “Ignore,” or answer it through your device,” he explained.
The Marque 2 is another tool to keep calling, listening, and viewing hands-free.
Users answer and ignore calls in a similar way. It also blocks background noise and minimizes wind interference through dual microphones.
The seven-gram Marque 2 can be powered up for up to six months, depending on use, as it enters DeepSleep mode when away from the paired phone.
“As the way we live and work continues to evolve, along with the increasingly remote workforces, Plantronics remains dedicated in helping people work smarter by providing products to help them work effectively across all work spaces,” said Doctolero.
The first headset company to develop software for headsets also offers it for free at the App Store and Google Play store.
“Our products allow you to simply communicate.”
Now available in PC stores nationwide, the Voyager Legend and the Marque 2 are priced at Php4,900 and Php3,600 respectively.

This iPhone Setting Can Make Beats Headphones Sound Better
Monster Beats by Dr. Dre Studio headphones were selling for rock-bottom prices on Black Friday — we even saw a pair of these once-overpriced headphones, which originally sold for $350, for $115. But headphone purists are dismayed at the sound of these flashy cans, mocking their powerful bass as overpowering and artificial. If you feel that way and you’re listening to these headphones on an iPhone, iPad or iPod Touch, here’s how to equalize their sound to your liking.
By default, iOS devices don’t offer the kind of equalizer you would see in a recording studio, giving you control over each tiny slice of the sound spectrum. But they do give you a couple of dozen easy-to-select choices for sound equalization. Among the 24 available settings, you’ll probably find one that pleases your ears, not only with Beats Studio headphones, but with any audio playback device you’d like to tailor to your particular tastes.
