Samsung Announces Hearing Loss Detection App and New Initiative
According to the World Health Organization (WHO), over 5% of the world’s population—or 466 million people—have disabling hearing loss. In Argentina, hearing impairment constitutes 18% of the existing disabilities according to Info LEG—86.6% of which experience hearing difficulties; 13.4% are deaf.
While those diagnosed with hearing loss can take necessary actions for their individual cases—taking preventive measures to avoid total deafness, getting hearing aids, learning sign language, etc—those who do not know what’s happening to them are subject to a more frustrating experience. This is especially true for children who may lose the chance to develop their cognitive skills and pursue higher education.
Using Technology to Bridge the Gap
uSound for Samsung is an initiative designed to bring technology to people with hearing loss—to help detect the risk of hearing loss and thus improve their quality of life in such essential aspects as communication and education, the South Korea-based company announced.
uSound Test is a free application that is designed to allow users to detect their hearing loss risk. According to the company’s press release, the app reproduces pre-calibrated sounds that users give feedback to. It then compares these results with its database, with the app reportedly detecting specific frequencies the user may have difficulty hearing. uSound Test is designed to analyze the auditory curve that results from the whole test to help determine the degree of hearing loss risk.
uSound for Samsung reportedly issues a report with the results, designed as “a risk indicator,” according to Samsung. Since the test is not designed to be a medical diagnosis, the app recommends users contact hearing health specialists when necessary.
Cynthia Giolito, senior manager, corporate citizenship, Samsung Electronics Argentina, said: “uSound for Samsung reinforces our mission to offer technology with a purpose that improves quality of life. We are very proud to embark on this path and we hope to have solid results that will promote hearing accessibility in more places.”
Through uSound for Samsung, the company hopes to use its technology and resources to:
- Raise awareness about hearing loss and improve public policies;
- Avoid irreversible damage to hearing organs;
- Encourage learning and cognitive development for children;
- Develop speech and facilitate social inclusion;
- Contribute to a more egalitarian society.
Working with the Community
The Government of Jujuy will provide resources and workspaces for the hearing loss-detection campaign, according to Samsung. uSound will continue to help improve hearing experiences with its products, including the aforementioned test and an app that turns the cell phone into an auditory assistant**, according to the company’s announcement. Samsung Electronics will provide the necessary technology to carry out a first pilot test of uSound Test in health centers across Jujuy and will financially support the project.
Governor Gerardo Rubén Morales, Jujuy Province, said: “It is a pleasure to accompany uSound, a company from Jujuy, take on its challenges. With the support of Samsung, this project will impact thousands of people with hearing problems. It is great that this project started in Jujuy. We hope it can be replicated throughout Argentina and in other countries—technological innovation knows no boundaries.”
As a team, the Government of Jujuy, uSound, and Samsung Electronics Argentina will help give a larger part of the Argentine community access to tools to potentially change lives through the use of technology.
Ezequiel Escobar, CEO and co-founder of uSound, said: “We witnessed a truly historic opportunity for our company and for Jujuy. This plan, using our technologies, will benefit many people from Jujuy and has the potential to expand to help many more people around the world. We are talking about a huge impact that grows even more with the support from Samsung and the Ministry of Health of Jujuy.”
Samsung has been preparing for entry into the hearing care market for several years; Hearing Review reported that the company filed an April 2013 patent for a “small hearing aid.” In 2015, Samsung placed a $13.9 million order for hearing aid amplifiers driven, according to a BusinessKorea article, by Vice Chairman Lee Jae-yong’s interest in what it called “mobile health care.” More recently, SamMobile reported in 2016 that Samsung applied for trademark registration of the term Earcle in South Korea, and that its application referenced hearing aids. Additionally, a Samsung device described as a “Samsung Bluetooth Hearing Aid” with the model number SM-R790, reportedly surfaced at the Bluetooth Special Interest Group’s (SIG) database.

Depression and Hearing Loss
Henley Hearing Clinic News:
Depression and its connection to hearing loss seems pretty logical and self-evident, especially if you’re a dispensing professional who experiences daily the difference that amplification can make in a person’s life. In fact, many clinicians find themselves explaining the connection as follows: a person’s hearing loss and related communication problems can lead to gaffes and social faux pas; leading to embarrassment, anxiety, and loss of self-esteem; leading to gradual withdrawal from social situations and physical activity; leading to social isolation and loneliness; and eventually bringing them down the path to depression.
While this is probably an adequate description for some cases, a recent webinar1 by Victor Bray, PhD, associate professor and former dean of Salus University’s Osborne College of Audiology, points to more recent scientific literature that paints a far more complex picture of hearing loss and its association with depression—one we all should be aware of. The utility of hearing aids, cochlear implants, and assistive devices is made no less important by this complexity; however, it’s vital to understand who might be most at risk for depression in your patient population, how best to administer simple screening tools (ie, the PHQ-2 or PHQ-9), and why it’s important to refer patients to a medical doctor or psychologist, when indicated.
Depression, also known as major depressive disorder (MDD), is present in 5-10% of the general population (up to 40% in some groups), and is a serious medical illness that negatively affects feelings, thoughts, and actions. The primary risk factors for depression are co-morbid chronic medical conditions (hearing loss is a pervasive chronic condition, especially among seniors) and recent stressful events. And, as with cognitive decline and dementia—the subject of my editorial last month—the stakes in treating depression are high for society and healthcare professionals. As Hsu and colleagues (2016) pointed out:
Depression is a common mental disorder, which affects 350 million people in the world. Unipolar depressive disorders and adult-onset hearing loss, the most common neuropsychiatric conditions, and sense organ disorder, respectively, are the first and second leading nonfatal causes of year loss due to disability among adults in high-income countries.2
Several of the studies reviewed by Dr Bray tend to suggest that the odds ratio for acquiring depression increases by a factor of about two if you have untreated hearing loss. However, a lot of the studies also show that a variety of chronic illnesses—ranging from cirrhosis to diabetes mellitus—can be associated with depression, so there could be some underlying neurophysiological common cause in hearing loss and other health problems that hasn’t been discovered yet. Dr Bray also looks at some very intriguing research about how dual-sensory loss (ie, hearing and vision loss) and sudden sensorineural hearing loss (particularly among young people) can greatly increase the risk for depression, as well as studies that are shedding light on how treated hearing loss might positively affect those suffering from anxiety, loneliness, and depression.
As Dr Bray explains, the linkage of hearing loss to depression could come from both a social (downstream) effect, as described at the beginning of this article, and a biological/neurological (upstream) effect, as proposed in a model by Rutherford et al.3 If that were the case, an effective treatment plan could involve therapy and/or medication from a psychologist, in coordination with a hearing device and/or auditory and cognitive retraining from a hearing care professional.
Dr Bray’s webinar was sponsored by Hamilton CapTel, and the company also sponsored an exceptionally interesting and well-viewed webinar last year about hearing loss and associated co-morbidities (including depression) by Harvey Abrams, PhD.4,5 When viewed together, they put an exclamation point on the fact that hearing loss isn’t just about the ears, it’s about health, the brain, quality of life, healthy aging, and so much more—while underscoring the crucial role of the hearing care professional in general healthcare.

Researchers Identify New Type of Vertigo, According to Study Published in ‘Neurology’
With vertigo, people have episodes of dizziness that can last from minutes to days. Vertigo can be caused by serious conditions, such as tumors, or conditions that are fairly benign, such the inner ear disorder Meniere’s disease. But for some people, no cause can be found.
In this new study, neurologists have identified a new type of vertigo where treatment may be effective.
“These conditions can be difficult to diagnose and quite debilitating for people, so it’s exciting to be able to discover this new diagnosis of a condition that may respond to treatment,” said study author Ji-Soo Kim, MD, PhD, of Seoul National University in Seongnam, South Korea.
To diagnose this new condition, the person sits in a dark room and the examiner moves the patient’s head forward and then the head is shaken horizontally for about 15 seconds. Then the patient opens his or her eyes and a video recording is taken of eye movements. The neurologists discovered that after the test, people with this new condition had eye movements called nystagmus that lasted longer than for other people. The new condition is called recurrent spontaneous vertigo with head-shaking nystagmus.
Among 338 people with vertigo with no known cause, 35 had this new condition and were included in the study. The participants had attacks of vertigo ranging from two or three times a week to once a year. They also experienced nausea or vomiting, headaches, and intolerance of head motions during the attacks.
The participants were compared to 35 people with other conditions that can cause vertigo, such Meniere’s disease, vestibular migraine, and vestibular neuritis. The test measured the time constant, or the time that represents the speed with which the reflexive eye movements can respond to change. For those with the new condition, the time constant during the primary phase of the nystagmus was 12 seconds, while it was six seconds for those with Meniere’s disease and five seconds for those with vestibular neuritis and vestibular migraine.
The neurologists also found that people with the new type of vertigo were more likely to have severe motion sickness than those with other types of vertigo.
A total of 20 of the 35 people with the new type of vertigo who had frequent attacks and severe symptoms were given preventive medication. About one-third of those had partial or complete recovery with the new medication. During the long-term follow-up of an average of 12 years after the first symptoms for 31 participants, five reported no more attacks, 14 said their symptoms had improved, and only one said symptoms had gotten worse.
Kim said that people with this condition may have a hyperactive mechanism in their vestibular system that helps the brain respond to movement of the body and in the environment.
“It’s possible that the vertigo occurs when this unstable mechanism is disrupted by factors either within the person’s body or in their environment,” Kim said.

‘CNN’ Profiles Inventor of HearGlass
Peter Sprague, the 78-year-old inventor of HearGlass—a technology that incorporates amplification into eyeglass frames—is featured in a recent CNN profile.
According to the article, Sprague was frustrated by how standard hearing aids “distorted audio” and has incorporated directional microphones, Bluetooth and WiFi capabilities, and a discreet design into his fourth-generation prototype.
Marshall Chasin, a frequent contributor to Hearing Review, was quoted in the article about the ways hearing aid manufacturers have improved their devices to help provide users with more dynamic sound options.

Salt- or Sugar-Based Solution May Diminish Noise-Induced Hearing Loss
It’s well known that exposure to extremely loud noises—whether it’s an explosion, a firecracker, or even a concert — can lead to permanent hearing loss. But knowing how to treat noise-induced hearing loss, which affects about 15% of Americans, has largely remained a mystery. That may eventually change, thanks to new research from the Keck School of Medicine of USC, which sheds light on how noise-induced hearing loss happens and shows how a simple injection of a salt- or sugar-based solution into the middle ear may preserve hearing, the school announced on its website. The results of the study were published in PNAS.
To develop a treatment for noise-induced hearing loss, the researchers first had to understand its mechanisms. They built a tool using novel miniature optics to image inside the cochlea, the hearing portion of the inner ear, and exposed mice to a loud noise similar to that of a roadside bomb.
They discovered that two things happen after exposure to a loud noise: sensory hair cells, which are the cells that detect sound and convert it to neural signals, die, and the inner ear fills with excess fluid, leading to the death of neurons.
“That buildup of fluid pressure in the inner ear is something you might notice if you go to a loud concert,” said the study’s corresponding author John Oghalai, MD, chair and professor of the USC Tina and Rick Caruso Department of Otolaryngology–Head and Neck Surgery and holder of the Leon J. Tiber and David S. Alpert Chair in Medicine. “When you leave the concert, your ears might feel full and you might have ringing in your ears. We were able to see that this buildup of fluid correlates with neuron loss.”
Both neurons and sensory hair cells play critical roles in hearing.
“The death of sensory hair cells leads to hearing loss. But even if some sensory hair cells remain and still work, if they’re not connected to a neuron, then the brain won’t hear the sound,” Oghalai says.
The researchers found that sensory hair cell death occurred immediately after exposure to loud noise and was irreversible. Neuron damage, however, had a delayed onset, opening a window of opportunity for treatment.
A simple solution
The buildup of fluid in the inner ear occurred over a period of a few hours after loud noise exposure and contained high concentrations of potassium. To reverse the effects of the potassium and reduce the fluid buildup, salt- and sugar-based solutions were injected into the middle ear, just through the eardrum, three hours after noise exposure. The researchers found that treatment with these solutions prevented 45–64% of neuron loss, suggesting that the treatment may offer a way to preserve hearing function.
The treatment could have several potential applications, Oghalai explained.
“I can envision soldiers carrying a small bottle of this solution with them and using it to prevent hearing damage after exposure to blast pressure from a roadside bomb,” he said. “It might also have potential as a treatment for other diseases of the inner ear that are associated with fluid buildup, such as Meniere’s disease.”
Oghalai and his team plan to conduct further research on the exact sequence of steps between fluid buildup in the inner ear and neuron death, followed by clinical trials of their potential treatment for noise-induced hearing loss.

New Hearing Devices in Development May Expand Range of Human Hearing
Researchers at Case Western Reserve University are developing atomically thin ‘drumheads’ able to receive and transmit signals across a radio frequency range far greater than what we can hear with the human ear, the University announced in a press release.
But the drumhead is tens of trillions times (10 followed by 13 zeros) smaller in volume and 100,000 times thinner than the human eardrum.
It’s been said that the advances will likely contribute to making the next generation of ultralow-power communications and sensory devices smaller and with greater detection and tuning ranges.
“Sensing and communication are key to a connected world,” said Philip Feng, an associate professor of electrical engineering and computer science and corresponding author on a paper about the work published March 30 in the journal Science Advances. “In recent decades, we have been connected with highly miniaturized devices and systems, and we have been pursuing ever-shrinking sizes for those devices.”
The challenge with miniaturization: Also achieving a broader dynamic range of detection, for small signals, such as sound, vibration, and radio waves.
“In the end, we need transducers that can handle signals without losing or compromising information at both the ‘signal ceiling’ (the highest level of an undistorted signal) and the ‘noise floor’ (the lowest detectable level),” Feng said.
While this work was not geared toward specific devices currently on the market, researchers said, it was focused on measurements, limits, and scaling which would be important for essentially all transducers.
Those transducers may be developed over the next decade, but for now, Feng and his team have already demonstrated the capability of their key components—the atomic layer drumheads or resonators—at the smallest scale yet.
The work represents the highest reported dynamic range for vibrating transducers of their type. To date, that range had only been attained by much larger transducers operating at much lower frequencies—like the human eardrum, for example.
“What we’ve done here is to show that some ultimately miniaturized, atomically thin electromechanical drumhead resonators can offer remarkably broad dynamic range, up to ~110dB, at radio frequencies (RF) up to over 120MHz,” Feng said. “These dynamic ranges at RF are comparable to the broad dynamic range of human hearing capability in the audio bands.”
New dynamic standard
Feng said the key to all sensory systems, from naturally occurring sensory functions in animals to sophisticated devices in engineering, is that desired dynamic range.
Dynamic range is the ratio between the signal ceiling over the noise floor and is usually measured in decibels (dB).
Human eardrums normally have dynamic range of about 60 to 100dB in the range of 10Hz to 10kHz, and our hearing quickly decreases outside this frequency range. Other animals, such as the common house cat or beluga whale, can have comparable or even wider dynamic ranges in higher frequency bands.
The vibrating nanoscale drumheads developed by Feng and his team are made of atomic layers of semiconductor crystals (single-, bi-, tri-, and four-layer MoS2 flakes, with thickness of 0.7, 1.4, 2.1, and 2.8 nanometers), with diameters only about 1 micron.
They construct them by exfoliating individual atomic layers from the bulk semiconductor crystal and using a combination of nanofabrication and micromanipulation techniques to suspend the atomic layers over microcavities predefined on a silicon wafer, and then making electrical contacts to the devices.
Further, these atomically thin RF resonators being tested at Case Western Reserve show excellent frequency ‘tunability,’ meaning their tones can be manipulated by stretching the drumhead membranes using electrostatic forces, similar to the sound tuning in much larger musical instruments in an orchestra, Feng said.
The study also reveals that these incredibly small drumheads only need picoWatt (pW, 10^-12 Watt) up to nanoWatt (nW, 10^-9 Watt) level of RF power to sustain their high frequency oscillations.
“Not only having surprisingly large dynamic range with such tiny volume and mass, they are also energy-efficient and very ‘quiet’ devices,” Feng said. “We ‘listen’ to them very carefully and ‘talk’ to them very gently.”
The paper’s co-authors were: Jaesung Lee, a Case Western Reserve post-doctoral research associate; Max Zenghui Wang, a former research associate now at the University of Electronic Science and Technology of China (UESTC), Chengdu, China; Keliang He, a former graduate student in physics, now a senior engineer at Nvidia; Rui Yang, a former graduate student and now a post-doctoral scholar at Stanford University; and Jie Shan, a former physics professor at Case Western Reserve now at Cornell University.

Which hearing aids are best for me?
Henley Hearing Clinic
You’ve been diagnosed with hearing loss and the hearing healthcare professional says you’ll benefit from wearing hearing aids, but which devices are best for you? The decision you make will depend greatly on the severity of your hearing loss as well as your health and the lifestyle you lead. Before you sit down to discuss options with your hearing healthcare provider, here are a few things to consider.
Are you a technology buff?
Hearing aids have changed a lot in the last ten years. Today’s devices are nothing like those your parents or grandparents may have worn, mainly because of advances in technology. While your parents’ hearing aids had to be adjusted with a tiny screwdriver by a hearing care provider, today’s digital devices are programmed via computer. Gone are the days of fiddling around with bulky volume control wheels and buttons. Most of today’s devices can be controlled discreetly by the wearer with smartphone apps as listening environments change. Bluetooth technology allows hearing aids to connect wirelessly to that smartphone you bought the moment it became available, tablets, televisions or car audio.
How much of a techie are you? Chances are, there’s a hearing aid that can keep up with your fascination for cutting edge gadgets. If you’re not a technology lover, don’t despair – the technology in your new hearing aids can also work behind the scenes automatically so you can just focus on hearing your best.
Is your world noisy?
Let’s face it — life can be loud! Depending upon what you do for a living and how often you’re socially engaged with people you love spending time with, directional microphone technology can help you make sense of that noise. Dual microphones in the hearing aid work to help you understand speech in challenging listening environments such as noisy conventions, crowded restaurants and bars or a family room filled with chattering children by focusing on the sound directly in front of you and minimizing sound to the sides and back.
Nearly all hearing aids today have some form of noise reduction built in. This technology is best for increasing your comfort in noisy situations, but it’s the directional microphones that have a noticeable impact on your ability to understand conversation in these same situations. Be honest about your lifestyle and talk with your hearing care provider about which features you need.
Are you self-conscious about your hearing loss?
Let’s be clear: there’s absolutely nothing wrong with wearing hearing aids — no matter whether they’re visible to others standing close to you or fit snugly out of sight inside your ear canal. These miracle devices not only help you hear your favorite sounds, they also alert you to emergency warning signals and decrease your risk of falling, developing dementia and feeling depressed. What’s not to love?
Unfortunately, some prefer to be more discreet about their hearing loss. For those individuals, tiny receiver-in-the-canal (RIC) or receiver-in-the-ear (RITE) styles with ultra-thin tubing and an availability of colors which blend with skin or hair may be desirable. For even more invisibility, invisible-in-the-canal (IIC) or completely-in-the-canal (CIC) styles may be an option.
The discretion of small hearing aids can come with some tradeoffs. Your hearing healthcare professional can help you decide, given the severity of your hearing loss and your personal preferences, which style is best for you.
Do you have dexterity issues?
Diabetes, Parkinson’s disease and other health conditions can cause numbness in the fingers or a decline in fine motor skills. The smaller the hearing aid, the smaller the features — such as the battery door or volume control. If you struggle with putting on jewelry or activities which require fine motor skills, you will likely benefit from wearing hearing aids that fit behind-the-ear (BTE) or a larger custom style. It’s much better to own devices you can operate confidently and effectively than one which frustrates you so much it spends more time in your nightstand than in your ear.
It’s important to remember that no two people or their hearing losses are alike, but there are hearing aids to suit most every need. The best hearing aids are the ones that work for you. Instead of waiting to make a decision because you’re afraid you’ll make the wrong one, find a hearing healthcare professional to guide you. Working as a team, the two of you can determine which devices will work for your unique hearing situation.
With the Oticon Opn, users can expend less effort and recall more of what they encounter in a variety of complex listening environments. This open sound environment, powered by Oticon’s Velox platform, allows for greater speech comprehension, even in a challenging audiological setting with multiple speakers. With its OpenSound Navigator scanning the background 100 times per second, the Opn provides a clear and accurate sound experience.
Latest research indicates that common ear infection drugs trigger bacteria to build defences, meaning that for some children and adults what does kill the bacteria, instead makes them stronger. Antibiotics used to treat ear infections can stimulate certain biofilms, which protect the bacteria, which may explain why infections return repeatedly.
A handful of bacteria cause ear infections in children. One of the most prominent is a type known as Haemophilus Influenzae (NTHi). This bacteria is found in the nose and throat does not cause any real issues yet can be very problematic in the ear. If the child is given sub-lethal levels of antibiotics the bacteria produce larger biofilms. “If you expose the bacteria to sub-lethal concentrations of the antibiotic while the biofilms are being formed, the bacteria make better Biofilms” said Paul Webster, researcher at the University of Southern California.
In a response to the rise of antibiotic resistance doctors have opted for an approach named “watchful waiting”; holding off from prescribing medication. If the infection does not get better in a few weeks then the doctor will treat it. Research indicates that doctors should be careful about what antibiotics are used. If you have suspicion that you are suffering from an ear infection you should visit your G.P. or pop in to see us at the Chalfont Hearing Centre, Little Chalfont, Amersham.
