- Article 1: HLAA Convention Research Symposium: Hearing Aid Research and
Development - Part One
By Larry Sivertson
~~~~~~~~~~~~~~~~~
Editor: The Research Symposium at the HLAA Convention provides an
opportunity for regular folks to learn about what's coming down the road for
people with hearing loss. Catherine Palmer, Associate Professor in the
Department of Communication Science and Disorders at the University of
Pittsburgh, moderated this year's panel, which included representatives from
major hearing aid manufacturers. Each panelist had ten minutes to present
his company's latest technology, followed by ten minutes for questions.
This is part one of three parts.
~~~~~~~~~~~~~~~~~
Phonak LLC
The first presenter represented Phonak LLC, and focused on three
technologies: SoundRecover, ZoomControl, and DuoPhone.
SoundRecover is the Phonak technology that shifts high frequencies that
people often have trouble hearing to lower frequencies where they hear
better. This often makes much more sense than amplifying frequencies at
which a person has little or no hearing. This technology was originally
provided to people with severe to profound hearing loss, but has since been
expanded to people with mild to moderate losses, and is now available in all
Phonak products. People generally report excellent sound quality with
SoundRecover, although it may take them a week or two to get used to it.
ZoomControl is the Phonak directional microphone technology that allows
the user to focus on sounds coming from any direction, not only those from
the front as with conventional directional microphones. This technology is
available in their premium products.
DuoPhone is the technology that provides for sound from a telephone to be
sent to both ears, a technique that can greatly increase comprehension. This
and other improvements are available because of the wireless communication
that allows streaming from one hearing aid to the other.
Q. How does SoundRecover differ from the AVR [Ed. A competing
manufacturer] algorithm?
A. We pick a cutoff frequency based upon the user's audiogram and shift only
frequencies above that cutoff. The AVR algorithm shifts all frequencies.
Q. You've focused on a "typical" hearing loss, which is primarily a high
frequency loss. I have a "cookie bite" loss. Are you doing any research that
will help me?
A. Our instruments are very flexible and your dispenser should be able to
program them to accommodate your loss.
Q. You mentioned that the hearing aids communicate wirelessly with each
other. Can you talk more about that?
A. Yes. That technology is available in all but our basic models. An example
of the communication is the DuoPhone, which I mentioned a minute ago.
Another is the ability to attenuate the volume in the left hearing aid when
you're using ZoomControl to focus on a sound on your right.
Q. I bought Phonak aids and loved all the things they did. But my
audiologist didn't understand much of it. Phonak refuses to talk directly to
consumers, so I wasn't able to use the aids. I returned them and bought
Siemens. Have you thought about providing direct consumer support?
A. Like the other major manufacturers, we work through the hearing care
professionals. We do have a consumer care line that can help you find an
audiologist.
Q. Does everyone like SoundRecover?
A. Most people do, but not all. And some people take a week or two to get
used to it. For those who don't like it, we can just turn it off.
Q. Do your aids that have DuoPhone also have telecoils?
A. Yes, but DuoPhone is only functional when the hearing aids are set to
microphone or microphone plus telecoil. Otherwise the user would be cut off
from the environment.
~~~~~
Siemens
The next speaker was Thomas Powers of Siemens. He covered their Best
Sound Technology, which includes Feedback Stopper, Speech Focus, and Sound
Learning 2.
The goal of Feedback Stopper was to set a new standard for eliminating
feedback in the presence of high gain. This has traditionally been
accomplished by creating a signal of the same frequency and opposite phase
to the offending signal. Feedback Stopper uses this strategy, and also
"fingerprints" the feedback so the hearing aid can identify it. This
strategy provides 28.5 db of additional gain, eclipsing the previous best of
24.5. This technology is available in all Siemens aids.
Speech Focus is Siemens' directional microphone strategy. It employs a a
hypercardiod pattern for sounds from the front, a reverse hypercardiod for
sounds from the rear, and an omni pattern for sounds from the sides. The
switching is all done automatically.
Sound Learning 2 is actually the third generation of the Siemens
technology that allows a hearing aid to learn the manual adjustments a user
makes in various acoustic environments, and eventually start making those
adjustments automatically.
Q. I'm wondering how someone using Speech Focus would know the sound is
coming from behind them.
A. It's just a natural learning process, just like with other hearing aids.
Q. My hearing aids have earmolds, and I hear myself much louder than I
hear others. Can my aids be changed to openfit, and would that solve this
problem?
A. People who use earmolds often comment on that effect of the occlusion
from the earmolds. Moving to openfit aids does solve that problem. But that
may not be possible if your instruments have high gain. Also, you should
check with your audiologist to see if it's possible to use your aids with an
open fitting.
Q. Does Sound Learning automatically adjust anything besides volume?
A. Yes, it also handles compression characteristics.
Q. Our Manhattan Chapter had some money from our walk, and we wanted to
install a loop in a local senior center. Unfortunately, only two of about 30
hearing aid users had telecoils, and only one knew how to use them. Do you
encourage audiologists to install telecoils and teach people how to use
them?
A. All of our hearing aids have telecoils unless they're just too small to
accommodate them. We do train audiologists on their use, and hope the
audiologists are doing their part.

- Article 2: Cochlear Implants: 2010 and Beyond - Part Four
By Cheryl Heppner
~~~~~~~~~~~~~~~~~
Editor: The folks in Virginia recently held their third cochlear implant
conference, and reporter extraordinaire Cheryl was there to record the
proceedings. I think she was just warming up for the summer conferences!
Here's her report. This is part four of four parts.
~~~~~~~~~~~~~~~~~
Cochlear Implants in the Future
To wrap up his presentation at the third state conference on cochlear
implants, Dr. Daniel Coelho of Virginia Commonwealth University gave us a
glimpse of current trends.
Pushing the age for implantation: Children are being implanted at younger
ages, and adults are being implanted at advanced ages.
Hybrids: Work is being done to combine the use of cochlear implants and
hearing aids in order to preserve hearing that is still available.
MRI Compatibility: Ways are being explored to make cochlear implants MRI-compatible
or allow for easier removal/insertion of the magnet.
Completely Implantable: Research is being done to learn how to
successfully implant the entire cochlear implant, including the processor.
Medical/gene therapy: Research is also being done to develop cures for
hearing loss.
Dr. Coelho was asked about the Lyric hearing aid. He said that the reason
it lasts so long on a single battery is due to its being placed in the ear
where it can be very close to where the sound is needed. This puts less
demand on the battery to supply volume and clarity.
He also talked about involvement in Cochlear's study of hybrid hearing,
in which a hearing aid and cochlear implant are combined in a single ear.
This technology is intended for people who have decent hearing at lower
frequencies and hearing loss at the higher frequencies. There is potential
for better speech understanding in a noisy situation. The device looks the
same as an implant outside the ear but has an added earpiece. Currently this
device is approved by the FDA only for research trials. The jury is not yet
in on whether the hybrid system is a good thing.
In a study of two to three years, 17 subjects have now been implanted. Of
those, 13 have had the systems activated. All are adults with progressive
hearing loss. Most are doing better with the system and continue to show
improvements.
At the close of his remarks, Dr. Coelho predicted that in the future
people would say of today's cochlear implants "I can't believe that is how
you got people to hear; it is so prehistoric."

- Article 3: The Sky is Falling! The Sky is Falling!
~~~~~~~~~~~~~~~~~
Editor: I usually avoid commenting on political issues, and I think I can
be true to that goal and still comment on this situation. That's because
this is an accessibility issue that Gary Shapiro and others are trying to
politicize. The bottom line is that these folks don't think that new
technology should be accessible to people with disabilities - and that's the
crux of THEIR press release (below).
If only we could get the arrogant and overbearing disability community to
stop oppressing the defenseless, mega-rich multinational corporations that
comprise the consumer electronics industry! If you'd like to share your
thoughts with the folks at CEA, you can send them to Megan Pollack at
mpollock@CE.org .
~~~~~~~~~~~~~~~~~
"Our objective is to meet the needs of disabled Americans while retaining
the freedom we need to continue as the greatest innovation creator," said
Consumer Electronics Association (CEA)(r) President and CEO Gary Shapiro in
testimony delivered today before a congressional committee. Testifying on
behalf of CEA, Shapiro made his comments before a hearing held by the House
Committee on Energy and Commerce's Subcommittee on Communications,
Telecommunication and the Internet exploring, "The 21st Century
Communications and Video Accessibility Act of 2009."
Shapiro agreed on the value of a centralized database of all products and
services for disabled Americans. He explained CEA's concern that H.R. 3101,
by requiring all Internet connected products and services be accessible by
Americans with all disabilities, would freeze technology and deter
innovation and entrepreneurs. Shapiro suggested several alternatives to the
end goal of providing Americans access to information, education and
entertainment. "The legislation before us - H.R. 3101 - is extremely broad
in its scope; chilling innovation and the entry of new products. More, it
ignores the increasing number of products on the market which serve the
needs of many in the disability community."
Shapiro noted that the current legislation does not take into account the
ever changing dynamic of Internet-based services and devices. "We are no
longer living in a world of single function devices...The legislation's
attempt to adapt old regulations established to apply to primary function
services and devices ...to new multi-function devices will not produce the
desired result, and will only impede the advancement of new technologies and
accessible features."
Shapiro suggested several amendments to H.R. 3101. "It is a core CEA
belief that the development of technical standards must be left to
consensus-based industry standards bodies, rather than government agencies
or Congress ...CEA has proposed the development of an advisory committee
consisting of all affected stakeholders working together to develop
industry-led technical solutions for IP-based video programming services and
devices." Already, CEA has established working groups to tackle remote
control usability by the visually impaired and to address closed captioning
in a digital age.
"We are also concerned about the draconian fines on manufacturers if they
do not meet the 'accessibility for everyone' requirements. More, CEA is
concerned about the barriers created for entrepreneurs and innovators by the
burdensome documentation and reporting requirements that take effect during
a product's design phase," said Shapiro. He also said the industry and the
FCC must be afforded flexibility with respect to the content and format of
any reports.
In closing, Shapiro said, "We have and will continue our efforts to
ensure that all Americans are able to reap the benefits of new and emerging
communications technologies. We look forward to working with all interested
stakeholders on a legislative approach that reflects the rapid innovation of
our market with the desire to ensure that these products and services are
accessible to persons with disabilities."

association promoting growth in the $165 billion U.S. consumer electronics
industry. More than 2,000 companies enjoy the benefits of CEA membership,

Editor: Here are our picks of some additional stories that you may find
interesting. For more, please point your browser to: http://www.hearinglossweb.com/news/curr.htm
~~~~~~~~~~~~~~~~~~~
NY Subway Information Booths Looped
Getting around on the New York subways just got a lot easier for
hard-of-hearing passengers. That's because station information booths are
now fitted with "hearing loops" thanks to the efforts of Janice Schacter,
chair of the Manhattan-based Hearing Access Program, and funds from
President Obama's stimulus package. "We had a shovel-ready project that fit
the criteria," says Schacter. Much as a Wi-Fi network delivers wireless
Internet access to computer users in coffee shops, a loop system takes sound
from an electronic source, such as a microphone or TV, and delivers it
directly to a hearing aid, right into a listener's head. Hearing loops are
relatively simple to install. The loop is created when a wire is installed
around the perimeter of the room or subway car and plugged into an audio
source. That wire then sends a signal to a tiny copper coil that's now
standard in most hearing aids. (Older hearing aids can usually be
retrofitted for about $250.)

Button Batteries Pose Serious Danger for Children, Elderly
There has been an increase in the use of "button" style lithium cell
batteries in recent years, which are used in many household productions
including remote controls, flashlights, watches, hearing aids, cameras,
children's toys and books, and musical greeting cards. There has also been a
significant increase in the number of battery ingestions, particularly among
children. New research published in the June issue of the journal Pediatrics
has found that between 1985 and 2009, there has been a 6.7-fold increase in
the percentage of battery ingestions, including 13 deaths involving button
batteries that become lodged in the esophagus. Certain battery types,
especially the 20-millimeter lithium cell battery, can also cause serious
injury if not promptly removed, such as tissue tears, burning, and internal
bleeding, because they continue to generate an external current, even when
weakened.

10 Signs You Need A Hearing Evaluation
The sooner hearing loss is diagnosed and treated, the better. Because
hearing loss does occur gradually persons find ways to compensate without
even knowing they are doing so. The following are common signs of hearing
loss:
1. You have trouble hearing people talking on the telephone.
2. You have trouble following a conversation when people are talking at the
same time
3. The family complains that the TV is too loud.
4. You strain to hear conversations.
5. You have trouble hearing in noisy environments.
6. You say 'What?' a lot.
7. People don't speak clearly. They mumble.
8. You misunderstand what people say.
9. You have trouble hearing children and women.
10. You become annoyed at others because you can't understand what they say.
