4 Listening Skills to Practice with your Hard-of-Hearing Child

When you have good hearing, it’s easy to take normal everyday sounds for granted without even realizing it.

However, for someone with hearing loss, developing listening skills takes practice. Even the beep of a microwave or the tweet of a bird can be totally new and surprising.

If you have a deaf child with a hearing aid or cochlear implant, I’m sure you’re used to visiting centres for speech and listening therapies. As helpful as those structured sessions are for developing listening skills, sometimes it’s easy for little ones to get bored and switch off because it’s a forced activity.

So here’s how we practice listening skills:

Get Outside

Lately, I have found that going for a simple walk outdoors and talking about all the different noises we can hear has proven to be more effective for Harry’s listening skills than anything else we have tried. Try stomping through a pile of crunchy leaves this fall and watch your child’s reaction to the rustling sound it makes. You could talk about the difference between the noise of a dry autumnal leaf as opposed to a fresh green leaf on a tree.

Harry and I like to sit on a bench watching different vehicles go past, and we talk about how a bus or truck make a ‘big noisy sound’, whereas a car is quiet and a bicycle, even quieter.

Go Shopping

I know going to a supermarket with a pre-schooler can be most parents’ idea of hell, but why not turn it into a listening experience?

Harry’s favorite thing to do is to listen to the cashier ‘bleeping’ the shopping at the checkout. I also like to ask Harry to go and get me apples or the milk and put them in the basket to test his listening abilities.

In the Car

There are so many different sounds in the car: the turn signals, horn, sirens whizzing past, and music coming through the speakers. I always used to worry that Harry would be overwhelmed in the car with all of these noises going on around him, but he has always really loved it.

We talk about things in and around the car and Harry often asks me. “What’s that?” when he hears a new sound.

At Home

Of course, you don’t actually have to go anywhere to have a listening experience, as there are hundreds of noises to hear in the comfort of your own home. We spend a lot of time in the kitchen and Harry loves sitting and waiting for the microwave to ‘ping’.

You could talk about the noise of a boiling kettle, or running water; what sausages sound like when they are sizzling in a pan, or the sound when toasts pops out of the toaster.

Hearing aid outcomes in older adults Implications for millions of adults with hearing loss

The first-ever placebo-controlled, double-blind, randomized clinical trial of hearing aid outcomes published today in the American Journal of Audiology shows that older adults benefit from hearing aid use.

Led by researchers at Indiana University with funding support (Grant No. R01 DC011771) from the National Institute on Deafness and Other Communication Disorders (NIDCD), the study sought to compare patient outcomes when hearing aids are delivered via an audiology “best practices” model compared with an “over-the-counter” (OTC) model. In the context of this study, the OTC model meant that patients received a high-quality, pre-programmed hearing aid that was not fitted by an audiologist.

The methodology is generally considered the highest standard for clinical trials.

“The research findings provide firm evidence that hearing aids do, in fact, provide significant benefit to older adults,” said Larry Humes, PhD, CCC-A, a distinguished professor in the Department of Speech and Hearing Sciences at Indiana University Bloomington and the study’s lead author. “This is important because, even though millions of Americans have hearing loss, there has been an absence of rigorous clinical research that has demonstrated clear benefits provided by hearing aids to older adults. Consequently, the U.S. Preventive Services Task Force has not been able to support widespread hearing screening for adults over age 50. This study, along with others to follow, will help establish the evidence base needed to foster better hearing health care for many older Americans.”

The study looked at 154 adults ages 55-79 years with mild-to-moderate hearing loss. All participants received the same high-end digital mini hearing aids fitted in both ears. Subjects were divided into three groups. One (the best practices group) received “best practices” services from audiologists that included professional fitting and counseling; one (the OTC group) received no professional fitting by an audiologist and selected their own pre-programmed hearing aids; and one (the placebo group) received a professional fitting but used a hearing aid that was programmed to provide no acoustical benefit.

Researchers found that hearing aids are effective in older adults for both the audiology best practices model and the OTC model. There were no significant differences in outcome between these two service-delivery approaches for five of the six outcome measures, but the OTC group fared somewhat worse when it came to satisfaction with their hearing aids. Fewer OTC participants were also likely to purchase their hearing aids after the trial (55% for the OTC group vs. 81% for the best practices group, with 36% for the placebo group). Following the initial 6-week trial, both the OTC and placebo groups were offered hearing aids under the best practices model. Satisfaction significantly increased for patients in both groups who chose to continue under audiologist care, and more participants opted to purchase their hearing aids after this continued period of care than after the initial trial.

In the United States, a large discrepancy exists between the number of people who could benefit from hearing aids and those who actually wear them. Close to 29 million U.S. adults could benefit from using hearing aids, according to NIDCD. Yet, among adults aged 70 and older with hearing loss who could benefit from wearing hearing aids, fewer than one in three (30%) have ever used them. Even fewer adults aged 20-69 (approximately 16%) who could benefit have ever used them.

In the study, researchers noted that NIDCD has prioritized identifying research areas that could lead to the improvement of hearing health care for adults with mild-to-moderate hearing loss — in particular, enhancing the accessibility and affordability of hearing health care. This study helps answer a high-priority research question of how current delivery systems can be used or modified to increase accessibility and affordability of hearing health care, according to study authors.

“More studies are needed to assess the generalization of the results obtained here to other patient populations, other devices, and other models of OTC service delivery,” said Humes, adding, “All of the devices used in this study were of high quality as opposed to the simpler, less expensive devices many associate with an OTC model. Also, all patients received a complete audiologic evaluation prior to treatment — another potential difference from some OTC models under consideration. These factors could impact patient outcomes. However, the results of this study should serve as a yardstick for comparing outcomes of future hearing aid studies.”

Hearing Loss Can Change How Nerve Cells Are Wired

Hearing Loss Can Change How Nerve Cells Are Wired

Published on

 

Common causes of occluded ears and temporary hearing loss like childhood ear infections and build-up of ear wax, or even the common cold–where everything sounds muffled, can lead to changes in the hearing system. Even short-term blockages of this kind can lead to remarkable auditory changes, altering the behavior and structure of nerve cells that relay information from the ear to the brain, according to a new University at Buffalo (UB) study.

The research, published online in the December 1, 2016 edition of the Journal of Neuroscience, investigated what happened when mice had their ears surgically blocked for a period of several days to “dampen” hearing. The investigators saw that some significant changes do occur within a few days. “What’s still unclear, however, is whether the cells return to their normal state when acoustic conditions return to normal,” said Matthew Xu-Friedman, PhD, the lead researcher and an associate professor of biological sciences in UB’s College of Arts and Sciences. We see in our research that the cells do seem to mostly bounce back, but we don’t yet know whether they completely recover.”

According to a recent announcement from UB, the changes the research team observed had to do with neurotransmitters — chemicals that help send signals from the ear to the brain. In mice whose ears were blocked, cells in the auditory nerve started to use their supplies of neurotransmitter more freely. They depleted their reserves of these chemicals rapidly each time a new auditory signal came in, and they decreased the amount of space within the cells that housed sac-like structures called vesicles — biological storage tanks where neurotransmitter chemicals are kept.

“When it’s quiet, the demands on the auditory nerve cells are not as great,” said Xu-Friedman in the announcement. “So it makes sense that you would see these changes: You no longer need as much neurotransmitter, so why invest in a lot of storage? If you’re not that active, you don’t need a big gas tank. And you’re not as afraid to use up what you have. This is one plausible explanation for what we observed.”

The changes in cellular structure and behavior were the opposite of what Xu-Friedman’s team saw in a previous study that placed mice in a consistently noisy environment. In that project, the mice’s auditory nerve cells started to economize their resources, conserving supplies of neurotransmitter while increasing the storage capacity for the chemicals.

“It looks like these effects are two sides of the same coin, and they might be the first hints of a general rule that nerve cells regulate their connections based on how active they are,” Xu-Friedman says.

In the more recent study, cellular changes began to reverse themselves when the mice’s ears were unplugged. When a treatment was “undone, the cells started to go back to what they were like before. Yet, it’s not clear to the researchers if the cells completely recover, so the team needs to do more research to see if that’s the case. Xu-Friedman also wants to study what happens when cells are repeatedly exposed to conductive hearing loss, as happens in some small children who get recurring ear infections. Xu-Friedman’s co-authors on the paper were first author Xiaowen Zhuang, a UB PhD student in biological sciences, and Wei Sun, PhD, UB associate professor of Communicative Disorders and Sciences. The research was suported by the National Science Foundation.

Science Has Uncovered Worst Sound on the Planet – And It’s Not What You Think

We consider hearing a gift. Each day we see  faces light up with joy as people hear sounds they are hearing for the first time in years. But even we find a few noises – an ambulance squealing down the street or the sound of teenager’s ringtone – so awful we sometimes wish we could program hearing aids (and ears!) to tune them out completely.

According to science, we’re not alone. In 2007, one British researcher went on a quest to uncover the most cringeworthy sounds on earth, according to people from across the globe. To start, University of Salford Professor of Acoustic Engineering Trevor J. Cox rounded up 34 horrible sounds, ranging from the whir of the dental drill to the smack of a cat eating. Next he put them online through a scientific survey that collected participants’ demographic data and allowed them to rank each sound. After one year and more than 1.1 million responses, the results were presented in a scientific paper presented at 19th International Congress on Acoustics.

And the worst sound in the world?

1. Vomiting

It may help to know that the sound in the study was actually a re-creation involving an actor, a bucket, and a can of baked beans. Still, the sound easily beat out fingernails on a chalkboard (a surprisingly low #16) to rank as the worst sound around thanks to the universal disgust it triggers in people across the globe.

Researchers say our revulsion may be an innate survival mechanism. If one member of a tribe shows signs of having ingested something harmful, sympathetic disgust can help others who ate the same thing expel it before they become ill.

Here’s what else made it to the top of the unfortunate heap. Turn up your speakers and see if you agree.

2. Microphone feedback

The concert-ruining squeal of audio feedback ranks high on the cringe list. Some scientists say this one also goes back to our evolutionary heritage. They speculate high-pitched squeals sound a like monkey warning calls, setting our primate brains on edge.

3. Crying Babies

Think one baby crying is bad? Try three or four.

Multiple babies crying outranked a solitary one, which still clocked in at number eight. Interestingly, men found a baby’s cry to be worse than women, who Cox speculates may be more habituated to the noise.

4. Train Scraping on Tracks

Not exactly music to the ears, is it?

5. Metal-on-Metal Squeaking 

The study used the sound of a squeaky seesaw to test a slightly less dramatic version of metal-on-metal. And no surprise, it’s grating.

Other sounds that made the top ten include badly played violin, a flatulent whoopee cushion, a single baby crying, soap opera argument, and electrical humming.

5 Everyday Jobs Where Workers Are Losing Their Hearing

Noise exposure is the world’s leading cause of hearing loss – but it hasn’t always been. Before the industrial revolution, humans’ exposure to loud noise was limited to the occasional storm or large gathering. But today, many of us need only head to work to experience noise loud enough to cause serious hearing damage.

The noises don’t have to be extremely loud, either. Just 85 decibels, roughly the sound of busy traffic, is enough to cause hearing damage within 8 hours. Over the course of a career, such continued noise exposure can add up to occupational hearing loss, damage to hearing directly related to the conditions of work.

Occupational Hearing Loss & Noise-Induced Hearing Loss (NIHL)

The vast majority of on-the-job hearing damage is noise-induced hearing loss, or NIHL (in a few jobs, occupational hearing loss may be caused by exposure to ototoxic, or hearing damaging, substances). While a single exposure to extremely loud noise (such as a gunshot) can cause NIHL, most occupational hearing loss is caused by being around sound loud enough to cause damage, but not discomfort. This type of work-related hearing loss may occur so gradually it goes unnoticed until it becomes a significant problem.

Unsurprisingly, people at the highest risk for noise-induced hearing loss include employees in the construction and manufacturing fields. According to the Centers for Disease Control and Prevention, individuals in the manufacturing sector account for 72 percent of recordable cases of occupational hearing loss.

But you don’t have to be surrounded by jackhammers or machinery to put your hearing at risk. Below are five groups of workers that face a substantial risk of hearing loss, despite working jobs most of us don’t associate with dramatic noise.

5 Surprising Jobs where Workers are Losing Their Hearing

1. Teachers: The rate of hearing loss in teachers below age 44 is 26 percent, compared with just 17 percent in the general population. Unsurprisingly, music and P.E. teachers may face the biggest risk, although a 2007 study measured the average decibel level of all classrooms at an unhealthy 87 decibels.

2. Plumbers: Working with metals and loud tools in small, enclosed areas is a recipe for hearing damage. Not surprisingly, almost half (48 percent) of plumbers report hearing problems.

3. Police officers: Hearing loss may seem like the least of a police officer’s on-the-job worries, but in fact, it is a serious and recognized problem. From discharging firearms to policing traffic or demonstrations, the noise demands on officers can be intense. Intense too, is the need to hear well in situations where split-second responses can save lives.

This has led some areas, such as New York City, to institute policies prohibiting officers who require hearing aids from serving. However, some fear such policies may backfire as officers choose to hide their loss rather than face an early retirement. The good news is, the tide seems to be turning as hearing technologies improve and stigma about hearing loss fades: In May, the city found in favor of four N.YP.D. officers who filed a case after being forced to retire due to hearing loss. The landmark settlement means that officers that can prove they can perform their essential duties, and pass an official hearing test, while wearing hearing aids, will be able to keep their jobs.

4. Truck Drivers: A 2010 study of 500 truckers found that 45 percent of truckers experienced high-frequency hearing loss, meaning they have trouble hearing high-pitched noises. Truck drivers tend to work long hours in a cab that can be even noisier than the traffic that surrounds them. Increasing their risk is exposure to exhaust fumes containing carbon monoxide, which studies have tied to hearing loss

5. Farmers Life on the farm is hard on the body, including the ears. Today’s agriculture workers face noise from large equipment like tractors and harvesters as well as guns, chainsaws, and even squealing pigs. Worse yet, many farmers begin working at young ages and may already be looking at more than a decade of cumulative hearing damage before the age of 30. Unsurprisingly, farmers experience one of the highest rates of occupational hearing loss, a factor that may further put them at an increased risk for other job-related injuries.

Could You Have Occupational Hearing Loss?

Because it can develop so gradually, many people with hearing loss may not even realize anything has changed. However, there are some tell-tale signs that often point to hearing loss. You may find yourself turning up the volume on the television, radio, or computer. You may have trouble understanding someone talking to you at close distance, particularly in places with background noise, such as a restaurant. Some people will also experience tinnitus, a ringing in the ears linked to hearing loss.
