Phonak introduces high-tech ceramic housings - Jan 24th 2011
With the introduction of the worldwide first high-tech ceramic housing, Phonak once again leads
the way in the industry by addressing the end-user’s even most demanding needs for high-value, durable,
comfortable and cosmetically appealing hearing aids. The slightly greater weight supports the added value feel
of these new deep black hearing aids compared to polymer housings.
Based on their unique properties such as extreme hardness and high mechanical strength,
excellent biocompatibility, esthetic appeal and thermal shock resistance, high-tech ceramics are being used for
example in the luxury goods industry as well as in aerospace applications. Phonak is very proud to introduce
this first class material to hearing aid housings, available for Audeo S Smart at two price
levels.
The extremely durable, abrasion-resistant surface ensures a scratch-free shine that lasts for
years. The polished finish makes the housing smooth to the touch and offers unmatched comfort when worn behind
the ear. Another feature of this fantastic material is its ability to quickly reach and maintain body
temperature, thus preventing perspiration behind the ear. Last but not least, the hypoallergenic properties make
the material especially kind to the skin and make ceramics hearing aid housings very hygienic. Lotion, sweat and
other daily influences will not alter these qualities.
The small and elegant hearing aid Audeo S Smart was the obvious choice for introducing the
high-tech material into the Phonak portfolio. Audéo S SMART is part of the award-winning Audéo product family, a
collection of tiny and stylish hearing aids with the power, flexibility and durability to fit different hearing
needs and lifestyles - and now empowered by the newest Spice technology. Audeo S Smart delivers top hearing
performance and unlimited connectivity, is easy to use, is built to last, and now, with high-tech ceramic
housing, will have a high-value appeal and be eternally beautiful.

Could Hearing Aids Delay
Dementia?
Published February 15, 2011
The results don't prove hearing
loss causes the mental decline by itself, but they fuel hopes that wider use of hearing aids might
help stem the rising tide of dementia.
Currently, more than one in 10
Americans over 70 have some kind of dementia and that number is set to balloon in the near
future.
"Dementia is devastating, and the
prevalence doubles every 20 years," said Dr. Frank R. Lin, an ear surgeon at Johns Hopkins
University in Baltimore, whose findings appear in the Archives of Neurology.
"There are some studies showing
that if you can delay dementia onset by just one year, you would decrease the prevalence of dementia
by more than 10 percent in 2050."
With funding from the National
Institute on Aging, Lin and colleagues followed more than 600 men and women over an average of 12
years. All had a hearing test done at the outset of the study; none was demented at that
point.
Overall, 9 percent of the
participants developed some type of dementia during the study, most commonly Alzheimer's
disease.
And the worse their hearing, the
greater their risk.
Those with mild hearing loss, which
can make it hard to follow a conversation in a noisy restaurant, had nearly twice the chance of
developing dementia compared to people with normal hearing -- even after ruling out the influence of
age and other factors.
The risk increased three-fold for
those with moderate hearing loss and five-fold for severe impairment.
"Does it mean you will develop
dementia if your hearing is impaired?" Lin said. "Absolutely not! But is your risk increased? You
betcha."
Lin said one small study from the
1980s had reached similar conclusions, but that the new study was the first to follow people over
time.
What's responsible for the link is
still unclear, however.
"That's the billion dollar
question," said Lin, adding that three different possibilities all seem likely.
Hearing loss and dementia might
share a common, unknown cause, for instance. Or, elderly people who are hard of hearing might have
extra difficulties coping with declining mental function. Further, the social isolation and
loneliness sometimes brought about by hearing impairment could also fuel the
dementia.
If one of the last two explanations
holds up, Lin said, that could potentially have a profound impact on
public health and
healthcare spending.
According to
the
National Institutes of Health, 17 percent of U.S. adults have some degree of hearing
loss.
"If you treat hearing loss, could
you possibly delay the onset of dementia?" Lin wondered, adding that he is currently running an
experiment to find out.
"Treating hearing loss is not going
to hurt you, except perhaps your wallet," said Lin. "We really need to begin studying what the exact
mechanism is. And we need to begin studying whether hearing aids could have an effect on the onset
of dementia."
Teens Get More Ear Infections When
Someone Is Smoking at Home
December 7, 2010 – Family members who smoke are more apt to feel
it is OK to smoke indoors as their children get older. But in households with secondhand smoke, children between 12
and 17 are 1.67 times more prone to have recurrent ear infections compared to adolescents who live in a smoke-free
environment, a large new study reveals.
Harvard researchers analyzed smoking behavior of 90,961 families surveyed between
April 2007 and July 2008.
“Overall, we found that the proportion of households that use tobacco products is the
same across all age groups, but family members are increasingly more likely to smoke indoors as their children
become preteens and teenagers,” said Summer Hawkins Ph.D., lead study author.
“The reason why secondhand smoke may cause ear infections is not known completely,
but secondhand smoke is an irritant and that may increase children’s and adolescents’ susceptibility to ear
infections.”
Their findings appear online in the Journal of Adolescent Health.
“Parents are usually pretty savvy and know it’s not in their children’s best interest
to smoke indoors,” said Ellen Wald, M.D., chair of pediatrics for American Family Children’s Hospital in Madison,
Wis. “When they say they never smoke indoors, I’m skeptical. They know that’s the answer people want to
hear.”
The study authors suggest that pediatricians should do more to make parents aware of
the hazards of secondhand smoke.
“Parents and health care providers need to work together to create a smoke-free
environment for their children,” Hawkins said. “Providers should ask parents about tobacco use during clinic
visits. Parents can reduce children’s exposure to secondhand by prohibiting smoke inside the home.”
While no simple answer exists, Wald said, “In order to change behavior you have to
talk about it. Physicians are in a good position to send the message that everyone’s vulnerable to secondhand
smoke, not just children and adolescents but adults as well.”

White noise therapy not
enough to curb Tinnitus
Feb 3rd 2011 - Tinnitus what many think of as "ringing in the ears" is the
perception of sound without any real acoustic stimulation. Sound masking therapy, a common component of tinnitus
treatment, is of uncertain benefit when used on its own, a new evidence review finds.
Tinnitus sufferers might hear one sound or multiple ones; they can hear them
continuously or intermittently. The sounds are imperceptible to others. For most people, the phantom sounds
hissing, whooshing and others hardly matter.
But for a small minority, tinnitus causes severe problems, such as anxiety, insomnia
and even major depression sometimes leading to suicide.
Jonathan Hobson, lead author of the new Cochrane review, said that sound therapy
relies on distraction, with an additional noise often called white noise reducing the contrast between the
patient's tinnitus signal and the background noise. This reduces the person's perception of the phantom sounds and
the distress they cause.
Hobson and colleagues at the Centre for Hearing and Balance Studies at Bristol
University, in England, summarized the results of six studies of 553 adults with persistent tinnitus who underwent
sound therapy either alone or combined with other treatments.
People receive sound therapy in several ways: by devices worn in or on the ear, by
headphones connected to an MP3-like device or with an under-the-pillow speaker for night use.
Sound masking rarely is a standalone therapy; other treatment methods usually
accompany it. Tinnitus therapies include medications, psychological interventions such as cognitive behavioral
therapy and holistic approaches such as acupuncture.
Most tinnitus sufferers are adults between about 50 and 70 years of age who also have
diminished hearing. Accordingly, for most, hearing aids represent a first line of treatment, improving the hearing
of actual external sounds and diminishing the phantom sounds at the same time.
The review was published by the Cochrane Collaboration, an international organization
that evaluates medical research. Systematic reviews draw evidence-based conclusions about medical practice after
considering both the content and quality of existing medical trials on a topic.
"[The review] does not provide high-quality evidence that sound therapy devices are
better than alternative treatments, but they are probably better than no treatment at all and certainly no harm or
adverse effects have been reported with their use," Hobson said. "The six trials included were all very different
in nature and compared sound therapy devices to a variety of other interventions: information, counseling, tinnitus
retraining therapy, hearing aids or no treatment.
