Electrical engineer to build more efficient integrated circuits for better hearing aids

Herb Booth
March 31st, 2015

A University of Texas at Arlington electrical engineering researcher is developing a more efficient, low-power integrated circuit for directional hearing aids that will lead to a better quality of life for hearing impaired people.

Sungyong Jung, an associate professor of electrical engineering, received a two-year, $144,000 grant from the Korean Electrotechnology Research Institute to build an integrated circuit for a tiny microphone that would mimic the auditory system of a Ornia ochracea – a parasitic fly known for its exceptionally miniscule ear.

The work holds promise for a growing population of people around the world with hearing problems, said Khosrow Behbehani, dean of the UT Arlington College of Engineering, said.

“Dr. Jung’s research is a wonderful example of how UT Arlington engineering faculty and their students are developing solutions that address critical issues in the area of health and the human condition,” Behbehani said. “A very important element in design of implants aimed at improving hearing is miniaturization. Minimizing the size while maintaining the highest level of function is a highly rewarding challenge that Dr. Jung is undertaking.”

How does treating hearing loss help with stress?

April 3, 2015 in Community News, Research

 

 

Better Hearing Institute 

The intensive listening effort demanded by untreated hearing loss can be extremely stressful.

Experts believe that even if you have just a mild hearing loss that is not being treated, cognitive load increases significantly.

Research shows that when left unaddressed, hearing loss is frequently associated with other physical, mental, and emotional health issues that diminish quality of life.

Withdrawal from social situations, a lessened ability to cope, and reduced overall psychological health are just some of the conditions associated with unaddressed hearing loss. Often, people with untreated hearing loss feel angry, frustrated, anxious, isolated, and depressed.

A 2014 study, in fact, showed that hearing loss is associated with an increased risk of depression in adults of all ages, but is most pronounced in 18 to 69 year olds.  Another study, conducted in Italy, looked at working adults—35 to 55 years of age—with untreated mild to moderate age-related hearing loss and found that they were more prone to depression, anxiety, and interpersonal sensitivity than those with no hearing problems.

HONOLULU —It’s a common sight around town: People going about their daily routine wearing earbuds and listening to their favorite books or music.

But many people, especially young ones, may be listening to music too loud and putting themselves at risk for losing their hearing.

“I think you’ve got to be careful. Keep it down so you can hear what’s around you to be safe,” said earbud user Scott Lawton.

Lawton loves the convenience of earbuds, especially when he’s exercising. David Thomas uses them, too, but understands the importance of keeping the volume low.

“Definitely, definitely. There’s always the chance of injury if you listen too loud or too long,” said Thomas.

The problem is that young people don’t seem to follow those rules.

 

 

RIT/NTID Offers Online Speech Recognition Test

RIT/NTID – Website
MARCH 3, 2015

Rochester Institute of Technology’s National Technical Institute for the Deaf has launched a website that provides individuals with one tool to determine whether they may benefit from hearing aids, allowing them to seek help sooner if that’s the case.

The test is free and can be found at: https://apps.ntid.rit.edu/NSRT.

“The test provides useful information and is recommended for anyone who is suspected of having a hearing loss,” said Joseph Bochner, who, with Wayne Garrison, worked on the website as a research project for several years.

Bochner, chairman of NTID’s cultural and creative studies department, and Garrison, a research faculty member in NTID’s Center on Access Technology, have spent years making sure the online test provides more accurate results than previously existing online tests offered elsewhere.

“This is a powerful diagnostic measure that has significant advantages over other measures of speech recognition,” Bochner said.

Deaf or Death? In Drug Trial, Parents Weigh Life vs. Hearing Loss

An experimental treatment could let children with a rare genetic disease live longer, but it may make them deaf

BETHESDA, Md.—While waiting for an infusion of a drug that might save his life, 15-year-old Andrew Marella gripped the controls of an NFL videogame, the hand-held version of a sport he played when he could still run without fear.

Andrew is in a clinical drug trial of cyclodextrin, a sugar-based substance that scientists hope will stop or slow the progress of a rare genetic disease that kills most patients by the time they are old enough to vote.

There is a good chance cyclodextrin will extend Andrew’s life. But his parents worry this will be the dose that leaves him deaf.

Families in the drug trial must decide whether to permit the higher doses of cyclodextrin that research shows might arrest the disease. Hearing loss is one side effect. “Deaf or death, what are our options?” said Andrea Marella, Andrew’s mother. “We have to keep moving forward.”

Auditory Pain Pathway May Protect Against Hearing Loss

Our hearing has a secret bodyguard: a newly discovered connection from the cochlea to the brain that warns of intense incoming noise that causes tissue damage and hearing loss, according to new research by Northwestern Medicine scientists.

Scientists believe they have identified the ear’s own novel pain system that protects it from very loud or damaging noise. It may be the reason you jam your fingers in your ears when a fire engine or ambulance wails close by. The nerves that normally alert you to pain – like touching a hot burner on a stove – are not present in your inner ear. So, it needs its own private alert system.

The discovery may provide insight into the cause and treatment for such painful hearing conditions as hyperacusis, an oversensitivity and earache in response to everyday sounds, common in soldiers exposed to explosives in the military, and tinnitus, a persistent and uncomfortable ringing in the ears.

The pathway, which scientists named auditory nociception (pain), is different from

How Old Is Too Old for Cochlear Implant Reimplantation?

February 20, 2015 in Research, Technology

 

 

For people with severe to profound hearing loss, cochlear implants can restore hearing and improve quality of life. Initially FDA-approved in 1985, only individuals with bilateral profound sensorineural hearing loss with no open set speech recognition (in other words, some ability to understand speech without visual clues) were considered viable candidates for cochlear implants.  The criteria have become less rigid over time, and more people are eligible including those with more profound residual hearing and pre-implant speech recognition scores. Occasionally, devices fail or medical complications create a need for revision surgery and reimplantation. The incidence of revision surgery is low, but outcomes are variable.

Some studies have suggested that advanced age may be associated with poor post-revision outcomes. Investigators from the University of North Carolina at Chapel Hill have completed a study that asks whether advanced age should be a contraindication for revision cochlear implantation.

Scientists warn of a ‘deaf generation’ that will lose the ability to hear as nature intended . . .

Scientists warn of a ‘deaf generation’ that will lose the ability to hear as nature intended as daily noise pollution reaches saturation levels

  • Generation exposed to constant noise could be losing the ability to hear
  • Noise pollution could be blocking out natural sounds that boost health
  • Hearing is ‘universal learning sense’ active even when we’re sleeping

A ‘deaf generation’ exposed to constant noise may be losing the ability to hear as nature intended, a sound expert has claimed.

As a result people could be missing out on the positive effects from natural sounds that contribute to good health and well-being, research suggests.

Dr Kurt Fristrup, who has monitored sound levels in 90 US national parks including Yosemite, Grand Teton and the Grand Canyon, stressed that hearing is a ‘universal learning sense’ active even when we are sleeping or anaesthetized.

Speaking at the American Association for the Advancement of Science (AAAS) annual meeting in San Jose, California, he said: ‘It’s not surprising since we’re seeing more rapid growth in noise and in population in our cities, the built environment is providing lots of cues that we find annoying or aren’t relevant to us, that people are putting on earphones or even noise-cancelling earphones, to just try and create a quieter or more congenial environment.

‘Of course what they’re missing, what’s being lost, is the ability to hear threats that are real. It’s the cry wolf phenomenon.

‘There will be the occasional cue that really matters – for runners I worry about this – but more importantly, even in our cities there are birds; there are things to appreciate in the environment as well.

Schools Favor Inclusion When Forced To Report Academic Progress

Disability Scoop
By MICHELLE DIAMENT
February 13, 2015

As Congress debates the role of testing, a new report finds that schools with the greatest accountability for students with disabilities are most likely to promote inclusion.

Schools held to more stringent academic reporting standards are more likely to deliberately transition kids with disabilities from self-contained to mainstream classrooms, according to the study from the U.S. Department of Education’s Institute for Education Sciences.

The findings suggest that educators may be more motivated to help students with disabilities achieve alongside their typically-developing peers when schools must account for progress.

Under federal education law, schools must regularly measure and report on the academic performance of students with disabilities as part of their obligation to make adequate yearly progress. However, the requirement is waived for some schools if their population of students with disabilities falls below a minimum threshold set by states.

Looking at schools in 12 states, researchers found that elementary schools that always reported on the progress of their students with disabilities purposefully moved children from segregated to regular classrooms at a rate that was 15.8 percentage points higher than those who never made such accountability reports. Among middle schools, the difference rose to 16.7 percentage points, the study found.

For the report, schools were asked in 2011 about the previous five years. Researchers also reviewed federal government data for the years 2005 to 2008 to identify schools considered “always accountable” — those that had to report on students with disabilities each year — and schools that never had to provide accountability during the time period.

For many young people, cranking up the music is what everyone’s doing. And, the louder it gets, the better.  But, your ears may pay the price later on. Many health experts are urging music lovers to dial down the volume. Recent research suggests there could be link between using ear buds and mild hearing loss in teens. Because what you do now will affect you for years to come. And, there’s no turning back.

“Often times small amounts of hearing loss can be kind of subtle. And, not necessarily right away,” says Dr. Brian Nicholas, Assistant Professor of Otolaryngology and Communication Sciences with Upstate University Hospital.

People who pop ear buds in for extended periods of time could be at risk for long-term damage. While you won’t have any noticeable signs immediately, the damage could creep up.

You may find yourself turning the volume up on your TV or phone, those are important warning signs.

If that happens to you, your ear is sending you a signal.

How Hearing Evolved from Water to Land

February 13, 2015 in Research

 

 

Science World Report
By Catherine Griffin
Feb 09, 2015

Lungfish and salamanders can hear, despite not having an outer ear or tympanic middle ear. Now, scientists are taking a closer look at exactly how hearing evolved about 300 million years ago.

The physical properties of air and tissue are very different. This means that up to 99.9 percent of sound energy is reflected when sound waves reach animals through the air. In humans and many other terrestrial vertebrates, the ear can be divided into three sections: the outer ear, the middle ear and the inner ear. The outer each catches the sounds waves and then directs them to the middle ear, where air pressure oscillations are transferred via the tympanic membrane and one of three small bones to fluid movements in the inner ear.

This configuration is important for hearing in present-day terrestrial animals. However, available fossils indicate that the tympanic middle ear evolved in the Triassic, which is 100 million years after the transition of the vertebrates from an aquatic to a terrestrial habitat during the Early Carboniferous.

In order to see how hearing evolved, the researchers studied the hearing of lungfish and salamanders, which have an ear structure that is comparable to different kinds of early terrestrial vertebrates. They measured auditory nerve signals and neural signals in the brainstem as a function of sound stimulation at different frequencies and different levels.

So what did they find? It turns out that the terrestrial adult salamanders and fully aquatic juvenile salamanders in addition to lungfish could detect airborne sound despite not having a tympanic middle ear. They sensed the vibrations induced by the sound waves.

The findings reveal a bit more about the evolution of hearing. More specifically, it shows that even vertebrates without outer and middle ears are capable of detecting airborne sound.

The findings are published in the journal Proceedings of the Royal Society B: Biological Sciences and The Journal of Experimental Biology.

Wanted – HARD OF HEARING OR DEAF FOR AN ONLINE SURVEY

February 12, 2015 in Community News, Research

 

ADULTS WHO ARE HARD OF HEARING OR DEAF
WANTED

FOR AN ONLINE SURVEY ABOUT VOICE TELECOMMUNICATIONS USE

The Rehabilitation Engineering Research Center on Telecommunications Access at Gallaudet University is conducting an online survey to learn about the experiences of adults who are hard of hearing, deaf or have hearing loss in their use of voice telecommunications technology in the U.S. (regular telephones, cell phones, captioned phones, Skype, etc.).

Our goal is to better understand how such adults use current voice telecommunications technology, what barriers they face using it, and what needs they have for improved accessibility. This is a particularly relevant topic right now as the Federal Communications Commission (FCC) is currently seeking updated information to assess whether the Commission’s HAC (hearing aid compatibility) rules effectively meet the needs of individuals who are deaf and hard of hearing. Summary data from the survey will be used to update the FCC.

For the purposes of this survey, voice telecommunications means that you both listen and talk for yourself during telephone calls, even if you also supplement your listening experience by using text (for example, relay or captioning) to read what the other person on the call is saying while you listen.

To take this survey you:

  1. must be 18 years or older
  2. have hearing loss and
  3. use voice telecommunications regularly (at least once a week).
  4. have access to the Internet in order to complete the survey.

The survey will take approximately 15-30 minutes to complete, depending on the extent of your telephone use.

If you completed the survey before, please do not complete it again. Please complete this survey only once.

To participate in the survey go to http://tap.gallaudet.edu/telecomsurvey/

For questions about the survey, contact:
Linda Kozma-Spytek at Linda.kozma-spytek@gallaudet.edu.

This study has been approved by the Gallaudet University Institutional Review Board.

 

 

Visual skills, technology key for ad agency’s hearing-impaired co-founder

January 23, 2015 in Community News, Hearing Loss & Deafness, Research, Technology

 

 

Geoff Akins sees things others don’t.

The Newport Beach visual arts entrepreneur, who co-founded advertising agency AkinsParker 10 years ago, has been the creative force behind campaigns for brands like Toyota Racing Development, Tiger Woods Foundation and Lexus F-Sport.

Akins is profoundly deaf. But he says he can sense what clients and audiences are feeling and translate that into his work. He’s adept at picking up on a client’s actions in subtle visual traits.

“My hearing impairment makes me uniquely skilled at some things as well,” he said. “For example, I’m pretty in tune with body language and unspoken communication, especially interpersonal communication.”

According to research at UC Davis and UC Irvine, deaf people are quicker at recognizing and interpreting body language than those who can hear.

David Corina, professor in the UC Davis Department of Linguistics and Center for Mind and Brain and graduate student Michael Grosvald, now a post-doctoral scholar at UCI, measured the response times of deaf and hearing people to a series of video clips showing people making American Sign Language signs or “non language” gestures, such as stroking the chin.

“The real surprise was that deaf people were about 100 milliseconds faster at recognizing non-language gestures than were hearing people,” said Corina, whose work was published in the 2012 journal Cognition.
