Hearing Health Foundation and Hearing Charities of America Join Forces

Hearing Charities of America (HCOA) and Hearing Health Foundation are excited to announce a newly formed partnership in an effort to collect hearing aids that will be given to low-income individuals through the HCOA’s national assistance program, The Hearing Aid Project.

One quarter of Americans ages 20 to 65 suffer from hearing loss, which makes it one of the country’s most widespread public health concerns. The Hearing Aid Project was created to provide access to affordable hearing health services, while creating collaborative relationships to support this mission.

Countless hearing aids sit unused in drawers or are discarded once new hearing aids are purchased. Hearing Health Foundation is now a collection center for The Hearing Aid Project to ensure that quality, donated hearing aids can be refurbished and given to those in need.

“Hearing Health Foundation is thrilled to join forces with Hearing Charities of America and do our part in collecting hearing aids to be refurbished and distributed to those who need them,” said Nadine Dehgan, HHF’s CEO. “Minimal health insurance and Medicare coverage, as well as out-of-pocket costs, have been a major hurdle for many who could benefit from using hearing aids. Until quality hearing healthcare is available to all of the 48 million Americans living with hearing loss, HHF is glad to be doing its part to provide hearing aid assistance to those in need,” Dehgan said.

Hearing Charities of America and Hearing Health Foundation believe that healthy hearing should be enjoyed by all. To donate your hearings aids to be refurbished, please contact Hearing Health Foundation at info@hhf.org or 212-257-6140.

THE HEARING HEALTH CHALLENGE

In celebration of Better Hearing and Speech Month in May, Hearing Health Foundation is launching the Hearing Health Challenge. Although hearing loss is commonly associated with one’s normal aging process, more than half of those with hearing loss are younger than 65. The top two war wounds for active military personnel and veterans are hearing loss and tinnitus, accounting for 60 percent of this population.

Unfortunately, only 13 to 33 percent of those who need hearing aids use them; financial constraints, the lack of a perceived need, and stigma are leading reasons why hearing loss goes untreated for an average of 7 to 10 years after diagnosis. Hearing Health Foundation is committed to reducing the stigma, educating the public on the dangers of noise, advocating for greater access to hearing health care, and funding the best science to find better treatments and cures for hearing loss and its associated disorders.

CHALLENGE

• For every hearing aid received within the month of May, a $200 cash donation will be made to HHF by an anonymous donor to support hearing research. 
   

• For every dollar donated within the month of May, that dollar will be matched up to $33,500 by an anonymous donor to support hearing research.

HHF is excited to have Drs. Bob Shannon and Ruth Anne Eatock as new members of our Board of Directors and we look forward to their contributions toward HHF’s mission. Please join us in giving them both a warm welcome!

AudiologyNow! 2017

By Kathleen Wallace

The American Academy of Audiology’s (AAA) annual conference, AudiologyNow!, took place in the Indianapolis Convention Center in early April. Although four days of lectures addressed nearly every aspect of the audiological scope of practice, one overarching theme emerged this year: How will the field of audiology evolve from here?

This past year has posed various disruptions to the field of audiology, such as how over-the-counter hearing aid legislation will change delivery of services, how the continued interest in personal sound amplification products (PSAPs, also called “hearables”) will guide consumer choice, and how to improve evaluations and interventions to best serve individuals with hearing loss. These questions, along with many others, fueled an exciting dialogue among professionals from around the country.

AAA President Ian Windmill, Ph.D., urged members of the academy to embrace disruptions to the field, including the recently introduced legislation for nonprescription hearing aids. Although these changes may appear as an encroachment on the audiological scope of practice, Dr. Windmill urged that these may actually be beneficial to the field.

Dr. Windmill said hearing healthcare has never been more in the public eye or as highly discussed by health officials, politicians, and consumers than in this past year. This increased awareness could lead to the prioritization of hearing health, as consumers grow more cognizant of the repercussions of hearing loss. Furthermore, the introduction of hearing solutions at various price points and technology levels may improve accessibility. If audiologists were to embrace these alternatives to intervention, they will successfully evolve with the field while simultaneously demonstrating to consumers their dedication to patient-centered care.

This sentiment was echoed throughout the conference’s sessions. Additionally, multiple lectures discussed how audiologists could improve delivery of patient-centered care by improving counseling skills, utilization of self-assessments, and consumer education to shift the locus of control from care provider to joint decision-making between the consumer and the hearing provider.

Lastly, leading professionals in the field encouraged a return to the audiologists’ roots as rehabilitative professionals. In the years since the audiological scope of practice expanded to include the ability to dispense hearing aids, audiologists have slowly shifted their focus from providing rehabilitative services to a device-driven service centered on hearing aids. However, the delivery of unprecedented auditory rehabilitation to foster successful communication strategies will enable our profession to succeed in the face of the many disruptions to hearing technology.

AAA’s willingness to acknowledge the challenges facing hearing healthcare is very promising to its successful evolution as a field. Although the field of audiology is currently experiencing some growing pains, many hearing healthcare professionals are embracing this opportunity to rethink the delivery of care and how to improve patient satisfaction by challenging the status quo.

A Balancing Act Before the Onset of Hearing

By Sonja J. Pyott, Ph.D.

Our ability to hear relies on the proper connections between the sensory hair cells in the inner ear and the brain. Activity of the sensory hair cells (red) and these connections ( green) before hearing begins is essential for the proper development of hearing. The research conducted by Sonja J. Pyott, Ph.D., and colleagues investigated the mechanisms that regulate this activity.

The development of the auditory system begins in the womb and culminates in a newborn’s ability to hear upon entering the world. While the age at which hearing begins varies across mammals, the sensory structures of the inner ears are active before the onset of hearing. This activity instructs the maturation of the neural connections between the inner ear and brain, an essential component of the proper development of hearing. However, we still know very little about the mechanisms regulating the activity of these sensory structures and their neural connections, specifically during the critical period just before the onset of hearing.

In our paper, “mGluR1 enhances efferent inhibition of inner hair cells in the developing rat cochlea,” soon to be published in an upcoming issue of The Journal of Physiology, we investigate the role of glutamate, a neurotransmitter, in regulating activity of the sensory structures and their connections in the inner ear before the start of hearing.

Neurotransmitters assist in the communication between neurons and are typically classified as either excitatory or inhibitory based on their action. Excitatory action results in stimulation; inhibitory action assists in the calming of the brain. Our research found that although glutamate typically excites activity, it also elicits inhibitory activity. This dual role for glutamate occurs because it activates two distinct classes of glutamate receptors: ionotropic glutamate receptors (iGluRs) and metabotropic glutamate receptors (mGluRs).

Importantly, this dual activation balances excitatory and inhibitory activity of the sensory structures, a balance of which is likely important in the final refinement of the neural connections between the inner ear and brain prior to the onset of hearing.

As part of future research, we will further investigate the role of mGluRs, one the distinct classes of glutamate receptors, in the development of hearing. We will also investigate if mGluRs balance excitatory and inhibitory activity in the adult inner ear, similar to its role prior to the onset of hearing. Insights into these mechanisms may identify new ways to modulate activity and prevent congenital or acquired hearing loss.

What's That Noise?

By Laura Friedman

In honor of World Tinnitus Day April 18, Hearing Health Foundation (HHF) wants to draw attention to the effects and challenges associated with tinnitus.

The U.S. Centers for Disease Control estimates some 15% of Americans—about 50 million people—have experienced tinnitus. Roughly 20 million people struggle with chronic tinnitus, while 2 million have extreme and debilitating cases. It is also a top war wound among active U.S. military personnel and veterans.

Tinnitus is defined as the perception of sound when there is no external, acoustic source. Individuals with tinnitus may describe the noise as buzzing, hissing, whistling, swooshing, or clicking. Roughly 90 percent of tinnitus cases occur with an underlying hearing loss.

Tinnitus can be either intermittent or chronic. People who experience intermittent tinnitus occasionally hear sounds in their ears that can last from minutes to hours after being exposed to excessively loud noises. An example would be someone sitting near the fence of a NASCAR race without wearing hearing protection. People with chronic tinnitus, on the other hand, often experience noise more frequently, which can last for more than three months.

The impact of tinnitus on everyday life differs from person to person. Researchers found that most people with chronic tinnitus are not too bothered by it. Many of these people prefer to only see a doctor for assurance that their tinnitus is not an indication of a serious disease or impending deafness. People who were bothered by their tinnitus reported that it was annoying, invasive, upsetting, and distracting in daily life. In a small tinnitus self-help group, some members frequently describe having problems sleeping, understanding speech, poor concentration, inability to relax, and depression.

People with age-related hearing loss, or presbycusis, may also experience a ringing, hissing, or roaring sound in the ears. Presbycusis progresses over time and is generally more severe in men than in women and the risk increases with age, as shown in epidemiological surveys.

Although there is no cure for tinnitus, there are available treatments that can minimize tinnitus symptoms. Tinnitus Activities Treatment (TAT), cognitive behavioral therapy (CBT), and Tinnitus Retraining Therapy (TRT) are sound therapies that can lessen the effects of tinnitus, often times very helpful in combination with counseling. Furthermore, by using hearing protection and noise reduction technologies, and by avoiding excessive noise, many people can prevent significant hearing problems.

Taking care of your hearing should always be part of keeping healthy overall. If you suspect a hearing loss or tinnitus, HHF recommends getting your hearing checked. If you do have a hearing loss or tinnitus, talk with your hearing healthcare professional about available treatments. For more information, visit hhf.org/tinnitus or email us at info@hhf.org.

Cortical Alpha Oscillations Predict Speech Intelligibility

By Andrew Dimitrijevic, Ph.D.

Hearing Health Foundation Emerging Research Grants recipient Andrew Dimitrijevic, Ph.D., and colleagues recently published “Cortical Alpha Oscillations Predict Speech Intelligibility” in the journal Frontiers in Human Neuroscience.

The scientists measured brain activity that originates from the cortex, known as alpha rhythms. Previous research has linked these rhythms to sensory processes involving working memory and attention, two crucial tasks for listening to speech in noise. However, no previous research has studied alpha rhythms directly during a clinical speech in noise perception task. The purpose of this study was to measure alpha rhythms during attentive listening in a commonly used speech-in-noise task, known as digits-in-nose (DiN), to better understand the neural processes associated with speech hearing in noise.

Fourteen typical-hearing young adult subjects performed the DiN test while wearing electrode caps to measure alpha rhythms. All subjects completed the task in active and passive listening conditions. The active condition mimicked attentive listening and asked the subject to repeat the digits heard in varying levels of background noise. In the passive condition, the subjects were instructed to ignore the digits and watch a movie of their choice, with captions and no audio.

Two key findings emerged from this study in regards to the influence of attention, individual variability, and predictability of correct recall.

First, the authors concluded that the active condition produced alpha rhythms, while passive listening yielded no such activity. Selective auditory attention can therefore be indexed through this measurement. This result also illustrates that these alpha rhythms arise from neural processes associated with selective attention, rather than from the physical characteristics of sound. To the authors’ knowledge, these differences between passive and active conditions have not previously been reported.

Secondly, all participants showed similar brain activation that predicted when one was going to make a mistake on the DiN task. Specifically, a greater magnitude in one particular aspect of alpha rhythms was found to correlate with comprehension; a larger magnitude on correct trials was observed relative to incorrect trials. This finding was consistent throughout the study and has great potential for clinical use.

Dimitrijevic and his colleagues’ novel findings propel the field’s understanding of the neural activity related to speech-in-noise tasks. It informs the assessment of clinical populations with speech in noise deficits, such as those with auditory neuropathy spectrum disorder or central auditory processing disorder (CAPD).

Future research will attempt to use this alpha rhythms paradigm in typically developing children and those with CAPD. Ultimately, the scientists hope to develop a clinical tool to better assess listening in a more real-world situation, such as in the presence of background noise, to augment traditional audiological testing.

Andrew Dimitrijevic, Ph.D., is a 2015 Emerging Research Grantee and General Grand Chapter Royal Arch Masons International award recipient. Hearing Health Foundation would like to thank the Royal Arch Masons for their generous contributions to Emerging Research Grants scientists working in the area of central auditory processing disorders (CAPD). We appreciate their ongoing commitment to funding CAPD research.

Understanding Auditory Processing Disorder

 By Frankie Huang

April 4 is Auditory Processing Disorder Awareness Day and the Hearing Health Foundation is highlighting the effects and challenges associated with living with APD.

Auditory processing disorder (APD), also known as central auditory processing disorder (CAPD), is an auditory deficit affecting how the central nervous system interprets verbal information. Those living with APD show impairments in sound localization, specifically their ability to isolate a sound source in social environments.

Approximately 5% of school-age children have APD. Children with APD often are uncertain about what they hear and have difficulty listening in loud background noises as well as understanding rapid speech. Often distracted, they can struggle to keep up with conversations which impedes their ability to read, spell, and follow oral directions.

Researchers found a correlation between working memory capacity, which is the ability to retain and manipulate information, and speech development. They found that working memory capacity was significantly lower in children with APD and may be the cause of their inability to separate and group incoming information and, in turn, lead to poor speech perception in noisy environments.

Other researchers found that peripheral hearing loss may affect performance in certain APD tests in older adults. Older adults with mild to moderate hearing loss did significantly poorer on tests that require recalling words, identifying high and low tone patterns, and repeating short sentences.

Although APD can be difficult to diagnose, there are telltale signs: poor auditory memory, difficulty identifying sounds, and a delayed response to verbal requests and instructions. APD is sometimes misdiagnosed as ADD/ADHD or dyslexia, so if you suspect you or a loved one may have APD, it is advised that they go through an individual comprehensive assessment with an audiologist for a more accurate diagnosis.

It is important to understand that research is still needed to understand auditory processing disorders, accurate methodologies for diagnosis, and the best interventions for each child or adult. Even though there are available strategies to treat children with APD, researchers are hard at work finding alternative treatments that will improve the lives of those suffering from APD.

Learn about Hearing Health Foundation’s 2016 Emerging Research Grants recipients who are conducting research to improve the lives of those affected by APD. These grantees are General Grand Chapter Royal Arch Masons International award recipients and we are grateful to the Masons for their ongoing support.

John Brigande provides commentary: Hearing in the mouse of Usher

Oregon Health & Science University

The March issue of Nature Biotechnology brings together a set of articles that provide an overview of promising RNA-based therapies and the challenges of clinical validation and commercialization. In his News and Views essay, “Hearing in the mouse of Usher,” John V. Brigande, Ph.D., provides commentary on two studies in the issue that report important progress in research on gene therapy for the inner ear.

One in eight people in the United States aged 12 years or older has hearing loss in both ears. That figure suggests that, if you don’t have hearing loss, you likely know someone who does. Worldwide, hearing loss profoundly interferes with life tasks like learning and interpersonal communication for an estimated 32 million children and 328 million adults worldwide. Inherited genetic mutations cause about 50 percent of these cases.

The challenge in developing gene therapy for the inner ear isn’t a lack of known genes associated with hearing loss, but a lack of vectors to deliver DNA into cells. Brigande, associate professor of otolaryngology and cell, developmental, and cancer biology at the OHSU School of Medicine, provides perspective on companion studies that demonstrate adeno-associated viral vectors as a potent gene transfer agent for cochlear cell targets.

The first study demonstrates safe and efficient gene transfer to hair cells of the mouse inner ear using a synthetic adeno-associated viral vector that promises to be a powerful starting point for developing appropriate vectors for use in the human inner ear. The second study demonstrates that a single neonatal treatment with this viral vector successfully delivers a healthy gene to the inner ear to achieve unprecedented recovery of hearing and balance in a mouse model of a disease called Usher syndrome. Individuals with Usher syndrome type 1c are born deaf and with profound balance issues and experience vision loss by early adolescence. The research teams were led by scientists from the Harvard School of Medicine.

Brigande sees these new studies as potentially spurring investment and kickstarting the development of new approaches to correct a diverse set of deafness genes. 

Hearing Restoration Project consortium member John V. Brigande, Ph.D., is a developmental neurobiologist at the Oregon Hearing Research Center. He also teaches in the Neuroscience Graduate Program and in the Program in Molecular and Cellular Biology at the Oregon Health & Science University. This blog was reposted with the permission of Oregon Health & Science University.

High-Tech Hope for the Hard of Hearing

"In 2011, the Hearing Health Foundation based in New York, created the Hearing Restoration Project, a consortium of fourteen scientists who agreed to work together toward that goal, partly with funding from the foundation. One of the originators of the project, Edwin Rubel, who was a co-discoverer of hair-cell regrowth in chickens, told me, “It’s potentially the best thing that ever happened, because it really does bring together a lot of different kinds of expertise.”

Hearing Health Foundation's work toward finding better therapies and cures for hearing loss and tinnitus was featured in the April 3, 2017 Issue of T High-Tech Hope for the Hard of Hearing he New Yorker Magazine. Read the article here.
