  • The amount of energy in the noise and the damage it can do to your hearing increases very rapidly as it gets louder. In fact, noise energy doubles for every 3 decibels (3dB) increase in the loudness of the sound - and 3dB is such a small increase in loudness that you probably wouldn't even notice it.
  • What sort of noise causes the harm? For young people in particular, the most dangerous noise is amplified music, for example in gigs and clubs. Headphones, car stereos and mobile phones are also having a bad effect on the hearing of young people.
  • Research shows that 25% of people listen to headphones at a level that will cause hearing damage. Follow the 60/60 rule - don't have your player above 60% of the maximum volume, and don't listen to it for more than 60 minutes at a time.

  • One study suggests that listening to headphones at 80% for 90 minutes a day can lead to hearing loss. The authors say that this can take years for the damage to show up, so young people might not notice a loss of hearing until they are in their late 20s. At 100% for only five minutes you could do damage.
  • dulled hearing difficulty in understanding speech feeling full inside your ears ringing or high-pitched noise in your ears
  • In night clubs - where much of the damage is done - do not stay long, don't go too often and keep well away from the loudspeakers - or go somewhere else where the music is not so loud.

News : New study provides guidelines for safe levels of iPod listening - 1 views

  • The study, by researchers at the University of Colorado at Boulder and Children's Hospital in Boston, indicates a typical person can safely listen to an iPod for 4.6 hours per day at 70 percent volume using stock earphones, according to Cory Portnuff, a doctoral researcher in CU-Boulder's speech language and hearing sciences department.
  • The researchers found that listening to music at full volume through an iPod for more than five minutes a day using stock earphones can increase the risk of hearing loss in a typical person
  • Typical individuals can tolerate about two hours a day of a decibel unit known as 91-dBA before risking hearing loss, Portnuff said. The term dBA stands for "A-weighted decibels, a scale that takes into account that the human ear has different sensitivities to different frequency levels,"

  • Loud sounds can stress and potentially damage delicate hair cells in the inner ear that convert mechanical vibrations, or sound, to electrical signals that the brain interprets as sound. "Over time, the hair cells can become permanently damaged and no longer work
  • No one set of earphones is more dangerous than another," he said. "While isolator style earphones are capable of producing higher levels of sound than earbuds, most people use them at a lower volume than earbuds because they block out background noise. It's important to monitor the level of volume control settings."

Groin-punch 'game' harms more boys - Health - Kids and parenting - msnbc.com - 0 views

  • An msnbc.com poll of 100 urologists, conducted by Truth On Call, showed that 30 percent of the doctors had seen or treated pre-teen and teen boys for testicular trauma in the past year, including severe injuries caused by so-called “sack-tapping,” in which boys ambush others at school and elsewhere.
  • The issue was highlighted by news last week that a 14-year-old Minnesota boy, David Gibbons, had to have his right testicle removed after a hallway assault. “This is, in fact, a form of bullying,” Atala said. “Someone may do that without realizing the consequences of their actions.”

The iPad: First Take From frog design | Blog | design mind - 0 views

  • “I love it,” said Esslinger from Vienna, where he teaches “convergent industrial design” at the University of Applied Arts. “The iPad is the beginning of a new category — one that is hyper-convergent and humanistic.”
  • For a device to be compelling as a “casual computer” it has to have both the right user interface and the right “form factor,” designer lingo for a manageable and easy-to-use industrial design.
  • “The iPad is merging humanistic innovation with a culture of design and interaction that reaches the levels of high art,” says Esslinger. “In a digital world mostly deprived of any truly inspired product and experience culture, Apple stands out even more. The nearly forgotten American Dream of excellence and success is alive thanks to Steve Jobs!”

Putting teeth into forensic science - 0 views

  • Livermore researcher Bruce Buchholz and colleagues at the Karolinska Institute are looking at victim's teeth to determine how old they are at the time of death. Using the Lawrence Livermore's Center for Accelerator Mass Spectrometry, Buchholz determined that the radioactive carbon-14 produced by above-ground nuclear testing in the 1950s and 1960s remains in the dental enamel, the hardest substance in the body. The radiocarbon analysis showed that dating the teeth with the carbon-14 method would estimate the birth date within one year. Age determination of unknown human bodies is important in the setting of a crime investigation or a mass disaster, because the age at death, birth date, and year of death, as well as gender, can guide investigators to the corr

Science Center bonuses are under the microscope - 1 views

  • "Speaking just for myself, I was concerned when I heard about these bonuses," said David Weber, chairman of the Zoo-Museum District's board. It stands out from "what we've heard from the other institutions and the cost-cutting measures they're taking."
  • In Boyle's case, Hellman said, the financial officer deserved her bonus, even though she started so late in 2010. "She gave us a really good transition," he said, "and we rewarded her for that outstanding contribution."
  • "It removes any concerns that taxpayers might have," Hellman said. "But we're still going to use incentive compensation in certain years and with certain people. We still believe it's right."
