teen health ears music decibels

  • 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.

    The average surface temperature of earth has increased more than 1 degree Fahrenheit since 1900 and the rate of warming has been nearly three times the century-long average since 1970. Almost all experts studying the recent climate history of the earth agree now that human activities, mainly the release of heat-trapping gases from smokestacks, tailpipes, and burning forests, are probably the dominant force driving the trend.

    Each year, approximately 8,000 Americans are bitten by venomous snakes. On average, 800 or so bites occur annually in California, home to an abundance of snake species, but only one family is native with highly toxic venom: rattlesnakes. In San Diego County, the number of rattlesnake bites is increasing as well as the toxicity of the attack.

    this is an article about how performing experiments on mice help understand why migraines effect women more. they have found that by injecting the mice with a certain hormone found commonly in women, the mice have showed the same behaviors as women do who have severe migraines. ultimately this experiment will help doctors/ scientist further understand women and migraines

study news iPod deafness

  • 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."
