- Article 1: HLAA Convention Research Symposium: Hearing Aid Research and
Development - Part Two
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
all the 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 two of three parts.

Oticon
The speaker from Oticon addressed their Advanced Wireless Processing,
which enables two hearing aids to work together in new ways. The goal is to
mimic the ability that people with normal hearing have to enter new acoustic
environments and adjust to them without conscious thought. The Oticon AGIL
solution is responsible for this, and it's available in most of their
instruments.
Three current areas of research are Spatial Sound 2.0, which uses
differences in sound arrival times and volumes to improve comprehension;
Speech Guard, which preserves more speech sounds without overprocessing
them; and Connect Plus, which enhances the connectivity to various Bluetooth
devices. The goal of these technologies is to enable the user to more easily
comprehend speech, which leaves more mental energy to participate in
activities.
Q. I haven't heard you talk about user inputs to your design process. Do
you consider user feedback in your research decisions?
A. We maintain a large database of consumers who participate in our research
on an ongoing basis.
Q. How can we get involved in that research?
A. We work with various universities, and they do the recruiting of
participants.
Q. I recently purchased Oticon Epocs, and I wasn't able to easily
manipulate the two buttons. I'm surprised something like that was able to
make it to the market. My audiologist said many users really like the
technology, but are disappointed with the user interface.
A. Manipulating hearing aid controls is always a tough issue. We have a
remote that makes those adjustments very easy.
Q. I work in the computer industry and I know there are ways that hearing
aids could totally eliminate things like fan noise. Why don't you do that?
A. (Moderator) These capabilities are often limited by the available
processing power, and the increased power consumption that would be
required.
Q. I'd like to see the hearing aid manufacturers help eliminate the
stigma of hearing loss. Why don't your ads show young, active people using
hearing aids?
A. (Moderator) Some of the companies have done that. But I've also heard
that people complain that the ads show young people when most hearing aid
users are older!
Q. I use a dryer every night, and I still have to have my hearing aid
repaired due to excessive moisture. Any ideas?
A. That's an acknowledged problem. We all do everything we can to insulate
the electronics and make the cases as watertight as possible, but some
people still have problems.
A. (Phonak) We have a moisture resistant hearing aid for severe to profound
losses. Many companies are also starting to nanocoat the cases, which
provides better moisture protection. These will be on the market soon.
A. (Moderator) Remember that every hearing has two openings, one for the
microphone and one for the battery door. So keeping moisture out is a real
problem.
~~~~~
Unitron
The next speaker was Elizabeth Vrchota from Unitron. She commented that
understanding speech in noise is the number one complaint of hearing aid
users, and that their SmartFocus technology incorporates several techniques
that all work together to address that problem. These include directional
microphones, speech enhancement (boosting of the frequency bands in which
speech is the dominant signal), noise reduction (reducing gain in the
frequency bands in which noise is the dominant signal), and volume control.
Testing performed by the University of Rochester and Louisiana Tech
documented a 16% gain in speech comprehension when all these techniques are
used together.
She also discussed Unitron's Smart Alert system, which works with their
hearing aids and alerts people to fire and other dangers. The system
includes a bed shaker, multiple sensors, a remote, and a recharger. When
activated, the system vibrates the remote and also sends a signal to the
hearing aids. Distinct signals can be programmed for different stimuli,
including the door, phone, and fire alarm. When the remote is placed in the
charger base, the bed shaker is activated rather than the remote.
Unitron was careful to make installation and setup of their Smart Alert
system simple. They asked a group of people raging in age from 35 to 82 to
install the system, and all were successful.
Q. Are there degrees of shaking? I recently got a memory foam mattress,
and my bed shaker no longer wakes me.
A. The current device only has one shaking intensity. But you can place it
under a pillow rather than under the mattress, and it will wake you.
Q. You mentioned noise reduction. We've been hearing about that for a
long time. The noise of people talking in the background is especially
troublesome. Are there technological advances that can filter out that kind
of noise?
A. What we can currently filter is non-speech. The problem we have is that
the hearing aid doesn't know which voice you want to listen to.
Q. I'm excited about the alerting system. Does it interface to a
monitoring service, so they can send someone if it alerts?
A. Currently, no.
Q. I think you all underestimate what we are willing to do to hear. For
me, performance is much more important than battery life or size.
A. (Moderator) Keep in mind that the people that attend this convention are
"advanced" users. Most people go through a progression from wanting
something invisible and unobtrusive to just wanting to hear. Most of us are
in the latter group.

- Article 2: WeatherText: Technology for Full Access to Weather and All
Hazard Alerts
By Cheryl Heppner
~~~~~~~~~~~~~~~~~
Editor: There's wonderful new technology that can greatly increase the
availability of weather and hazard alert information to people with hearing
loss. Unfortunately, it's not currently available, and may not become
available for some time. Here's Cheryl's report.
~~~~~~~~~~~~~~~~~
Last week I learned about an exciting new technology called WeatherText
at the monthly meeting of the Deaf and Hard of Hearing Consumer Advocacy
Network (DHHCAN). I represent the Association of Late-Deafened Adults in
this national coalition of organizations of, by, and for deaf, hard of
hearing, late-deafened and deaf-blind individuals.
At various locations across the U.S. there are approximately 1,000
transmitters that send reports throughout the day to warn us of bad weather.
Those transmitters can reach about 98% of the country. Unfortunately while
there are "accessible" weather radios on the market, they don't provide the
same critical details in text that other people are receiving from the radio
by voice.
A presentation on WeatherText by Bob Mroz of HY-TEK and Bill Werner of
Werner Labs showed that this does not have to continue. Through new
technology, there is now a way to transmit both text and voice on the same
channel at the same time without one interfering with the other. The system
has been tested extensively with the NOAA test transmitter located at the
NOAA headquarters in Silver Spring, Maryland and in the company's office
over the past several years with no faults or failures.
Mroz spent 30 years working at the Federal Communications Commission and
was their director for advanced technology at the end of his career there.
He and Werner brought two prototypes of a WeatherText receiver to the
meeting that looked like a larger version of a remote control. There was a
small screen for viewing text.
Additional Advantages of WeatherText
- Clicking one button on the protoype device allowed me to scroll forward
or back through the text. This is a great step forward. Current weather
radios broadcast the same message over and over. If you are busy with
something else or interrupted, you can't stop the text, or make it go
backward or forward. If you miss critical information, you have to wait for
it to be rebroadcast.
- In a noisy environment it would also be easier to read text than strain
to understand the radio voice. Mroz and Werner believe WeatherText is not
just for people who are deaf or hard of hearing but that it may actually
become "the mode of choice" for people who use currently listen to the voice
broadcasts on NOAA Weather Radio.
- Weather radios are inexpensive to make. Mroz and Werner used radios
from Radio Shack to build their device at a cost of about $12 each. There is
much that manufacturers could do. Font size could be made adjustable and
text could be received in multiple languages.
What's Holding Us Back? All this sounds good. The catch?
You can't get this service as an add-on to the existing weather radio.
Approximately $10 million is needed to install an encoder at those 1,000
national weather radio sites. DHHCAN coalition representatives at the
meeting were also very concerned to learn that the Weather Radio Improvement
Plan (WRIP) to improve NOAA weather radio, started in 2008 by the National
Weather Service, is already behind schedule. WRIP called for the addition of
text capability to weather radio, but it has not been given a priority.
There is a danger that adding text messaging could be dropped or continue to
be delayed.
Questions and Answers
Q: What's the difference between what you get on weather radio and what
you get in the text alerts about weather from CNN or other sources?
A: Weather radio is designed to be available during bad weather, and
information from national weather radio is most likely to be available
during bad weather. National weather radio will also get its alerts out
before CNN because many sources get their information from national weather
radio.
Q: Can you use weather radio for whatever location you are in, or does it
only work for a place you select?
A: It will work in the location you take it to; that is automatic.
Q: Can this service be converted into everyday equipment so we don't need
a second device to get weather radio alerts?
A: Yes, Subaru is already including national weather radio in their car
radios.
Q: Can it be added to smart phone apps?
A: Smart phones rely on cell towers, and that makes them vulnerable for
receiving information in bad weather conditions. The display is the largest
part of the equipment so it could be added to anything.
Q: How does this compare with the Commercial Mobile Alerting System
(CMAS) which is limited to messages of 90 characters?
A: There is storage for 4,000 characters in the current WeatherText device.

- Article 3: Hamilton CapTel(r) Introduces iPhone(r) App for Mobile
Captioned Telephone
~~~~~~~~~~~~~~~~~~
Editor: We're getting used to seeing all kinds of cool technology that
improves the quality of life for people with hearing loss. The latest of
these is the App from Hamilton CapTel, which provides captions on an iPhone.
Here's their press release.
~~~~~~~~~~~~~~~~~~
Today, Hamilton CapTel announced the immediate availability of the
Hamilton Mobile CapTel application for the iPhone. The application provides
captions of telephone calls for individuals with hearing loss while they are
on the go. Available nationwide, Hamilton Mobile CapTel allows users to
listen while reading captions of everything that is said during phone calls
- all from the convenience of their iPhone.
"This is a major addition to the Hamilton CapTel family of solutions,
delivering unprecedented access and freedom for iPhone users that are hard
of hearing," said Dixie Ziegler, vice president of Hamilton Relay, provider
of Hamilton Mobile CapTel service. "At Hamilton, we are dedicated to
delivering personalized service and providing the most technologically
advanced solutions. Every call is important, and due to the widespread use
of the iPhone, we have created a free iPhone App that is easy-to-use with an
intuitive interface to meet the needs of iPhone users in the U.S."
Similar to captions on television, Hamilton Mobile CapTel delivers
captions for telephone conversations. The popularity of the iPhone in
particular has spurred creation of an iPhone App that is free, easy and
highly functional. The Hamilton Mobile CapTel iPhone App delivers several
useful features that meet the demands of people who are hard-of-hearing:
- Listen to what is said while simultaneously reading captions of what's
said on the screen of the iPhone
- Integration of Contacts; phone numbers are available when it's time to
place a call
- Free captions in both English and Spanish
- Available on any 3G/3GS iPhone
- Works with an iPhone compatible headset---wired or Bluetooth
- Registered Web CapTel users can download the app immediately and have
access to their profile and contacts stored on the iPhone, captioning can
begin within seconds
"The development of the iPhone App was paramount for our tech-savvy
users. CapTel Service has changed people's lives for the better---no more
frustration trying to hear the person at the other end of the phone," said
Ziegler. "Now, iPhone users can place and receive captioned phone calls from
just about anywhere. And best of all, this is a free service, available
throughout the United States."
Hamilton Mobile CapTel is a service that can be used on a single, mobile
telephone that is capable of supporting both voice and data simultaneously
through a 3G or Wi-Fi connection. While initially only available for the
iPhone 3G/3GS, due to resounding demand, Hamilton Mobile CapTel has plans to
provide this service on a variety of devices.

Saving the music industry from itself
I'd say I'm an audiologist who specializes in serving a misunderstood,
underserved market where hearing is mission critical. My primary work is to
prevent hearing loss in musicians. It's an interesting job, as I have worked
with over 1000 famous musicians, and many more not-so-famous ones. It all
started back in the 1980s when a local band here in Chicago came to me for
help because the lead singer was having hearing problems and was going to
quit. I was able to help her, and she kept performing. So basically, I saw a
need, an empty space where there should be some sort of prevention program
in place, and nobody was doing anything about it. I thought it was time
somebody did.

Novel bioplastic to boost performance of bionic devices
A young researcher has developed conductive bioplastics that will boost
the performance of bionic devices such as the cochlear ear and the proposed
bionic eye. "Our plastics will lead to smaller devices that use safer
smaller currents and that encourage nerve interaction," says biomedical
engineer Rylie Green of University of New South Wales (UNSW). Her plastics
are already being tested in prototype bionic eyes and she hopes they will
find application wherever researchers are attempting to integrate
electronics with the human body.

Rockville parents opt for Cued Speech
In 2005, Rockville residents Steve Scher and Grace Consacro learned their
twin daughters, Lola and Ella, were born with hearing losses. The parents,
who have hearing loss, said they wanted their daughters to grow up learning
and communicating with the spoken word, as they had. At 18 months, Lola and
Ella underwent surgery for cochlear implants. Many of the couple's deaf
acquaintances and friends criticized them for the decision. "Some deaf
people think you should wait and let the children decide," Consacro said.
"But we thought it was important to do it. We saw it as the best choice
possible for the children." The couple's son, Max, born two years later,
received cochlear implants at 14 months. After several years of raising
their children to learn a type of communication among the deaf and hard of
hearing known as Cued Speech, the couple was recently honored with the
national Cueing Family Award at a ceremony at Flower Valley Elementary
School in Rockville, where Consacro teaches.
