Gene Could Helps Scientists Understand Genetic Deafness
2012-01-04 14:17:59

Researchers at Washington University School of Medicine report they have found new clues that may help scientists understand the genetic causes of deafness. The gene FGF20 has been associated with inherited deafness in otherwise healthy families.  The FGF20 gene codes for one member of a family of proteins known as fibroblast growth factors. Members of this family are known to play important and broad roles in embryonic development, tissue maintenance and wound healing. "When we...

High MP3 Player Volume Can Damage Hearing
2011-12-29 09:31:21

Using MP3 players at high volume puts teens at risk for early hearing loss, say TAU researchers Today's ubiquitous MP3 players permit users to listen to crystal-clear tunes at high volume for hours on end – a marked improvement on the days of the Walkman. But according to Tel Aviv University research, these advances have also turned personal listening devices into a serious health hazard, with teenagers as the most at-risk group. One in four teens is in danger of early hearing...

Nine out of 10 city dwellers may have enough harmful noise exposure to risk hearing loss, and most of that exposure comes from leisure activities. Historically, loud workplaces were blamed for harmful noise levels. But researchers at the University of Michigan found that noise from MP3 players and stereo use has eclipsed loud work environments, said Rick Neitzel, assistant professor in the U-M School of Public Health and the Risk Science Center. Robyn Gershon, a professor with the...

A study by the University of the Americas (Universidad de la Américas Puebla) in Mexico and the Basque Institute for Agricultural Research and Development, Neiker-Tecnalia, highlights the fact that noise pollution has negative effects on songbirds in cities. The field work, carried out in urban parks in the Metropolitan Area of Puebla-Cholula (Mexico), reveals that the green zones most affected by noise have less bird species.  Among the birds better adapted to urban...

Bigger Birds Hit Hard By Human Noise
2011-11-10 09:35:45

Large birds with low-frequency songs are less likely to nest near noisy sites A growing body of evidence shows that man-made noise is bad for birds, but some species are harder hit than others – particularly bigger birds with low-frequency songs, finds a new study. "Bigger birds sing at frequencies that are more easily masked by the low frequencies typical of human noise pollution," said lead author Clinton Francis of the National Evolutionary Synthesis Center in Durham, North...

Inhaling low levels of CO reduces the impact of environmental stress, TAU researcher finds According to scientists, carbon monoxide (CO), a tasteless, colorless and odorless gas, is not only a danger to the environment but also highly toxic to human beings. Found in the exhaust of vehicles and generators, CO has been dubbed the "silent killer" because excessive inhalation is lethal, poisoning the nervous system and heart. Now, in a surprising twist, Prof. Itzhak Schnell of Tel Aviv...

Many people who are hard of hearing wear hearing aid devices (instruments) that are unsatisfactory in several ways: (1) over time they become loose fitting, (2) always make whistling noises, (3) they pick up random feedback, (4) amplify wind noise, (5) produce shrill squeals, (6) cause painful sores, (7) are generally uncomfortable and hard to keep in place. This new Weber "Noise Be Gone" Hearing Aid Liner (Patent Pending) is designed to overcome and eliminate all of these problems with this...

Many hearing aids wearers have negative feelings about the noise and discomfort they experience while wearing their hearing aids. For example, hearing aids can produce annoying and unwanted wind noises plus many other disturbing squeals and beeps. This new product takes away those problems and more... Toms River, NJ (PRWEB) September 26, 2011 Many hearing aids wearers have negative feelings about the noise and discomfort they experience while wearing their hearing aids. For example, hearing...

Tel Aviv University researcher uses revolutionary fast-track sequencing to identify genetic causes for deafness Over 28 million Americans are hearing impaired, and 50 percent of these cases can be traced to genetic causes. The condition can be especially challenging for children born hearing impaired because spoken language, reading, and cognitive development are tied to hearing. That makes early diagnosis essential for identifying appropriate therapy and treatment. Unfortunately,...

Reducing Jet Noise By Controlling Turbulence
2011-09-13 06:08:00

  Supercomputing aids scientists in developing a novel technique to reduce jet noise Airlines and aircraft manufacturers are under increasing pressure to keep noise levels low for airport personnel and for people in surrounding neighborhoods. In fact, about every 10 years, the International Civil Aviation Organization, whose recommendations influence policies in the United States and abroad, reduces the maximum noise an airplane can produce before it can be certified and sold to...
