Very Loud Music Can Cause Hearing Loss In Adolescence

Very Loud Music Can Cause Hearing Loss In Adolescence.
Over the finish two decades hearing sacrifice due to "recreational" noise exposure such as blaring blackjack music has risen among adolescent girls, and now approaches levels previously seen only amid adolescent boys, a new study suggests. And teens as a whole are increasingly exposed to snazzy noises that could place their long-term auditory health in jeopardy, the researchers added. "In the '80s and dawn '90s young men experienced this kind of hearing damage in greater numbers, undoubtedly as a reflection - of what young men and young women have traditionally done for farm and fun," noted study lead author Elisabeth Henderson, an MD-candidate in Harvard Medical School's School of Public Health in Boston.

And "This means that boys have usually been faced with a greater caste of risk in the form of occupational noise exposure, fire alarms, lawn mowers, that sympathetic of thing. But now we're seeing that young women are experiencing this same level of damage, too". Henderson and her colleagues piece their findings in the Dec 27, 2010 online version of Pediatrics.

To explore the risk for hearing damage among teens, the authors analyzed the results of audiometric testing conducted centre of 4,310 adolescents between the ages of 12 and 19, all of whom participated in the US National Health and Nutrition Examination Surveys. Comparing booming noise uncovering across two periods of time (from 1988 to 1994 and from 2005 to 2006), the line-up determined that the degree of teen hearing loss had generally remained relatively stable. But there was one exception: teen girls.

Between the two investigate periods, hearing loss due to loud disturbance exposure had gone up among adolescent girls, from 11,6 percent to 16,7 percent - a plain that had previously been observed solely among adolescent boys. When asked about their past day's activities, look at participants revealed that their overall exposure to loud noise and/or their use of headphones for music-listening had rocketed up, from just under 20 percent in the overdue 1980s and early 1990s to nearly 35 percent of adolescents in 2005-2006.

About Music And Health Again

Certain aspects of music have the same force on proletariat even when they live in very different societies, a new study reveals. Researchers asked 40 Mbenzele Pygmies in the Congolese rainforest to attend to short clips of music. They were asked to hearken to their own music and to unfamiliar Western music. Mbenzele Pygmies do not have access to radio, goggle-box or electricity. The same 19 selections of music were also played to 40 amateur or practised musicians in Montreal.

Musicians were included in the Montreal group because Mbenzele Pygmies could be considered musicians as they all trill regularly for ceremonial purposes, the study authors explained. Both groups were asked to merit how the music made them feel using emoticons, such as happy, sad or excited faces. There were significant differences between the two groups as to whether a particular piece of music made them feel good or bad.

However, both groups had like responses to how exciting or calming they found the different types of music. "Our major idea is that listeners from very different groups both responded to how exciting or calming they felt the music to be in similar ways," Hauke Egermann, of the Technical University of Berlin, said in a item release from McGill University in Montreal. Egermann conducted part company of the study as a postdoctoral fellow at McGill.

Adjust Up Your Health

The inventorying of suspected benefits is long: It can soothe infants and adults alike, trigger memories, reduce pain, help sleep and make the heart beat faster or slower. "It," of course, is music. A growing body of probe has been making such suggestions for years. Just why music seems to have these effects, though, remains elusive.

There's a lot to learn, said Robert Zatorre, a professor at McGill University in Montreal, where he studies the keynote at the Montreal Neurological Institute. Music has been shown to assist with such things as pain and memory, he said, but "we don't recollect for sure that it does improve our (overall) health".

And though there are some indications that music can touch both the body and the mind, "whether it translates to health benefits is still being studied," Zatorre said. In one study, Zatorre and his colleagues found that multitude who rated music they listened to as pleasurable were more likely to surface emotional arousal than those who didn't like the music they were listening to. Those findings were published in October in PLoS One.

From the scientists' standpoint, he explained, "it's one aspect if people say, 'When I also harken to this music, I love it.' But it doesn't barrow what's happening with their body." Researchers need to prove that music not only has an effect, but that the effect translates to well-being benefits long-term, he said.

One question to be answered is whether emotions that are stirred up by music extraordinarily affect people physiologically, said Dr. Michael Miller, a professor of medicine and commander of the Center for Preventive Cardiology at the University of Maryland Medical Center in Baltimore.

For instance, Miller said he's found that listening to self-selected cheerful music can improve blood flow and possibly promote vascular health. So, if it calms someone and improves their blood flow, will that move to fewer heart attacks? "That's yet to be studied," he said.

Music Helps To Restore Memory

Music Helps To Restore Memory.
You separate those popular songs that you just can't get out of your head? A different study suggests they have the power to trigger strong memories, many years later, in commoners with brain damage. The small study suggests that songs instill themselves very much into the mind and may help reach people who have trouble remembering the past. It's not confident whether the study results will lead to improved treatments for patients with brain damage.

But they do proposal new insight into how people process and remember music. "This is the first study to show that music can bring dow a overthrow to mind personal memories in people with severe brain injuries in the same way that it does in fine fettle people," said study lead author Amee Baird, a clinical neuropsychologist. "This means that music may be advantageous to use as a memory aid for people who have difficulty remembering personal memories from their career after brain injury".

Baird, who works at Hunter Brain Injury Service in Newcastle, Australia, said she was inspired to fire the study by a man who was severely injured in a motorcycle accident and couldn't recall much of his life. "I was interested to see if music could help him bring to mind some of his personal memories. The mortals became one of the five patients - four men, one woman - who took on the part of in the study.

One of the others was also injured in a motorcycle accident, and a third was hurt in a fall. The decisive two suffered damage from lack of oxygen to the brain due to cardiac arrest, in one case, and an attempted suicide in the other. Two of the patients were in their mid-20s. The others were 34, 42 and 60. All had celebration problems. Baird played million one songs of the year for 1961 to 2010 as ranked by Billboard journal in the United States.
