Ways To Easily Tell If Your Hearing Aid Is On

Why Do Hearing Aids Make My Voice LOUD? | The Occlusion Effect

When wearing hearing aids for the first time, there is a lot of uncertainty that goes along with it.; After all, it’s a change in your life.

Hearing aids are like any piece of technology. When it’s a brand new element in your life, there can be some frustrations that come along with it, but also some excitement. If all goes well, this new electronic gadget is going to make your life easier! It will be the same for you with your hearing aids.

Some people worry a lot about their hearing aids and want to be sure they are doing everything right. It can be tricky to know if an electric device is reaching its full potential, so you might have some questions about using a hearing aid.;One question that might arise is whether your hearing aid is actually working, so here are six ways to make sure your hearing aid is functional.

Is Your Earmold Broken Old Or Ill

Just like we service our cars hearing aids require servicing. Earmolds, tubes and receivers tend to deteriorate over time and need to be replaced. Upon inspection of tubes you may find they have shrivelled up, bent, changed colour or split resulting in hearing aid feedback. Just as our nose grows over time our ears tend to change shape over time as well.;

This could mean a once perfectly fitting mould/custom piece might now be causing unpleasant hearing aid feedback due to being loose or misshaped. An appointment with your hearing professional will be necessary to eliminate this issue. This is because new impressions for new earmolds/custom shells are required to allow for better-tailored moulds/custom hearing aids to your changed ear shape.;

Is The Hearing Aids Inserted Correctly In Your Ear

If the hearing aids are not inserted correctly into your ear canal it is bound to whistle. Remember right color code on hearing aid goes to the right ear and the blue indicator means it goes to the left ear.

Also, please attempt to push the hearing aid down deep inside of your ear canal as possible. There should not be any portion of the aid sticking out of your ear canal. If you are not sure if it is inserted correctly, ask a friend to see if it looks right. If the hearing aid is making your ear sore, chances are is that you are inserting the hearing aid wrong.

Phase Cancelling Feedback Systems

It was around 1999 that Danovox came out with the industry first feedback reduction system. It was then quickly purchased by GN Resound and the first big-time hearing aid that had any feedback suppression was the Resound Canta BTE hearing aid.

Basically, the hearing aid used destructive interfering to cancel out feedback noise.;The system in 1999 wasnt great. It would often take things in the environment and cancel them out too, such things like a microwave beep. Plus, the system took time to react and was not that fast. Luckily, computer chips have advanced since then.

Pressure On The Tympanic Membrane

Recap of "The X

Your tympanic membrane is commonly known as the eardrum. If something is putting pressure on the tympanic membrane it could be quite uncomfortable, painful or perhaps cause dizziness.;

Generally speaking, hearing aids do not cause any pressure on the eardrum. The ear canal is about 30mm long and hearing aids are not inserted so deeply that they hit the eardrum. Also, air pressure is unlikely to build up as the hearing aids have vents in them to prevent this.

But if something went wrong it could be possible. Often patient forgets to clean their hearing aids and the vent gets occluded by ear wax. If the hearing aid was dirty enough to completely seal itself in the ear and then the person changes altitude it could create pressure. Although I would highly doubt this would be enough to create dizziness.

Another worst case example might be that a dome fell off into someones ear canal and they accidentally put a q-tips in their ear to scratch the itch they feel and it pushes the dome down against the eardrum. I have actually seen this happen. A patient who did have a dome sitting against his eardrum and he reported feeling dizzy and off balance until it got removed a few hours later.

However, those domes were not pushing on the eardrum.So, that leads to another theory.;

How To Stop Your Hearing Aid From Whistling

Mar 26, 2021 | Hearing Aids, Patient Resources, Troubleshooting |

Is your hearing aid making an unusual whistling sound or producing feedback? Then it could be a sign of an issue with your device.

As a hearing aid wearer, you understand the importance of regular maintenance and check-ups with your audiologist. Not only does it keep your device and hearing in top health, but it also allows us to look out for any manufacturer issues or changes in your hearing.

During these appointments, we often get reports from patients who have noticed an unusual whistling sound from their devices. So, if youve suddenly noticed a change in your hearing aids performance, youre not alone.

In fact, an unwanted screeching or chirping is one of the most common issues reported to us at Aim Hearing and Audiology Services. The good news is that there are plenty of things you can do to completely remove it and get your hearing aid back to brand new.

During this short video and blog, I will be explaining all things you should consider if youre in this situation.

No Feedback Systems In Hearing Aids

Before digital circuits in hearing aids, the only methods to use to prevent feedback are the methods that I discussed above with making the earmold or dome tighter in the ear canal. But the feedback was commonplace and made it so many people could not get the volume they needed out of their hearing aids. Unfortunately, some cheap hearing amplifiers dont implore any feedback system still.

Why Do Hearing Aids Whistle

Sometimes hearing aids are making a high-pitched noise, ringing or screeching. There may be several reasons for hearing aids whistling. Some of the causes of hearing aid feedback are listed here.

  • Wax in the ear canal. This could force the sound back out of the ear and cause the hearing aid to whistle.
  • The hearing aids are set to a very high volume.
  • The ear mould doesnt fit properly.
  • The cap is covering the hearing aids.

Problem: Dead Hearing Aids

Why Do I Hear Static? | Advanced Hearing Aid Feature: EXPANSION

If youve ever been to a movie only to have your hearing aid die out midscene, you know too well the frustration that can occur with batteries. During the pandemic, you may drain your batteries especially quickly because youre using them for hours at a time streaming music or FaceTiming, Ashby-Scabis says. Its cumbersome to change them, too.

The fix: Consider a hearing aid with rechargeable batteries. These have built-in batteries that dont require regular removal. In our 2018 survey, more than half of respondents who wear hearing aids rated rechargeable batteries as one of the most important features.

You simply dock your hearing aids each night on a charging unit, similar to your cell phone, Ashby-Scabis says.

But if youre not due for a hearing aid upgrade anytime soon, there are things you can do to prolong battery life. Turn the aid off when youre not using it, and leave the battery compartment door open overnight, to allow any moisture that has built up to evaporate, she says.

What It Means When A Hearing Aid Starts Squealing Or Screeching

  • Date: August 16, 2018

You love almost everything about your hearing device. You can pick up on sounds you had nearly forgotten about: birds chirping, bees buzzing, and other low, tranquil noises. However, theres one new sound you could easily do without: the squealing noise that sometimes occurs when you adjust or remove your hearing aid.

Ways To Make Sure Your Hearing Aid Is On

1.; Make sure the battery door is completely closed.

For a hearing aid to work, its battery door needs to be entirely closed. Closing the battery door pushes the battery into place, completing the circuit, so if this isn’t done, the hearing aid won’t be receiving power. If you’re struggling with this, remove the battery and flip it over, then reinsert and close the door.

2.; Take the hearing aid off and cup it in your hand.

You should hear a high-pitched squeal coming from the hearing aid. This is the feedback loop of the hearing aid similar to when you hold a microphone near a speaker and everything gets very loud very fast.

3.; With the hearing aid in your ear, rub your finger over the microphone.

It is important to remember that when wearing a behind-the-ear hearing aid, the microphone is located at the top of your ear, not in the ear. When rubbing the microphone, you should hear a scratching or static noise in that ear.

4.; If you have multiple programs set in your hearing aid, press the program button or use your remote to change the programs while your hearing aids are in.

Your hearing aid should make a sound to indicate the program change, like a beep or a boop.

5.; With your hearing aids out, turn the volume of your television or radio to a comfortable level for you.

Leave the volume where it is and put your hearing aids in. You should notice a change in volume or clearness with your hearing aids in, and you may find yourself wanting to turn the volume down.

How Does Hearing Aid Feedback Occur

Hearing aid feedback occurs when sound that was supposed to go into your ear canal leaves your ear and jumps back into the hearing aid microphone. The sound then gets reamplified, and this causes your hearing aids to whistle.

This feedback can happen in different contexts, like when you put your hearing aids;on in the morning and take them off in the evening, or when someone hugs you. This is perfectly normal because the hearing aids are reacting to the sound bouncing back from your surroundings.;;

Hearing aid feedback could also be a sign that something could be wrong with your hearing aids, or they need to be cleaned. In that case its best to consult your hearing care professional.

Earwax Causing Hearing Aid Feedback

Recap of "The X

If you get wax in your ear or if a piece of dead skin from your ear drapes across your ear canal, your hearing aid will go into feedback. The amplified sound hits the wall created by the wax or dead skin and the aid goes into feedback. The solution is to clean the ear.

Patience and Persistence

Feedback is a common problem, one that every practitioner has had a lot of experience dealing with. Be patient and also persistent. This problem requires some work, but it can be solved.

One last thought. People with substantial hearing loss hope that their new hearing aids can be fitted quickly and easily. Sometimes they can. However, in some cases, whether because of feedback or some other issue, it takes extra work and time to get the fitting right. In those cases, six or seven office visits may be needed rather than three or four.

Success is always possible. You can help by having extra patience.

How To Fix Annoying Hearing Aid Problems

Irritated by feedback, background noise, sore ears, or dead batteries? Here are practical solutions to five common issues.

Hearing aids can be a lifesaver. But though the technology has improved in recent years, these essential devices can still sometimes cause annoyance. And for many Americans, the ubiquitous mask-wearing during the pandemic has made using hearing aids more challenging than usual.

Were seeing patients come in with more complaints related to their hearing aids, and many are reluctant to visit their audiologist to make the necessary adjustments and changes to make wearing them easier, says Douglas Hildrew, MD, an ear, nose and throat specialist at the Yale School of Medicine in New Haven, Conn. If you ignore these seemingly minor annoyances, youre less likely to wear your hearing aids, which can compound the effects of COVID-19 isolation, he adds.

Here are five common problems that often come up with these devices, how to try to fix them on your own, and when to seek help from your audiologist.

Possible Vegas Nerve Interaction

With the above story of a dome in the ear canal causing a dizziness, it leads me to my own theory which I cannot collaborate by any research study. So take it for what is it worth, basically, this is a educated guess.

My guess is that a hearing aid or dome or any other object may be stimulating the Vegas nerve causing dizziness or other odd symptoms.;Let me provide a little background on the Vegas nerve/cranial nerve X.

It provides feeling to the skin and muscles of the ear canal and part of the throat, supplies sensory information to the brain for the throat, lungs, heart and digestive tract, plays a role in taste. Moter function includes the throat, heart and digestive tract.

So why do I think the Vegas nerve has anything to do with the dizziness? It is because it is the nerve that runs very close to the ear canal. Often when something touches the side of the ear canal it stimulates this nerve and a person feels like they want to cough.;

What I dont understand is how stimulating the Vegas nerve creates dizziness because it does not innervate with the vestibular system at all. But as it innervates with the heart and lungs it could affect more than what I am aware of.

Problem: Irritating Feedback Sounds

Hearing a screech, squeal, loud buzz, or hiss? When sound is amplified and escapes from the ear canal, it can be fed back through the tiny microphone on the device, causing a high-pitched squealing sound referred to as acoustic feedback, Shoup says.

In a 2018 survey of Consumer Reports members, more than a quarter of respondents who wear hearing aids rated feedback suppression as one of the most important features they looked for when purchasing their current hearing aid. While newer hearing aid technology has made feedback less of a problem, you may notice it more during the pandemic, Ashby-Scabis says, because the band on your face mask may rub against your hearing aid, causing noise.

The fix: If youre just noticing feedback but dont usually have problems, you can try repositioning your hearing aid dome so that it fits in your ear better, Hildrew says.

If that doesnt work, he advises that you see your audiologist or ENT. When you wear hearing aids, you are more likely to experience wax buildup in your ear canal, which can trigger feedback. If your ears are clear, your audiologist can adjust your ear molda more secure fit prevents sound from leaking outor reprogram the device, Shoup adds.

Problem: Too Much Background Noise

Why do some hearing aids whistle?

This is a common complaint, especially among new hearing aid users.

Many people expect that hearing aids will only amplify the sounds they want to hear and not the other background noises around them, Palmer says. The way hearing aids actually work takes some time to get used to, she adds, but usually resolves once your brain has had time to adapt to all the newly amplified noiseespecially if you wear your hearing aids full-time.

Still, even the seemingly minor background noise of being in a grocery store or talking to people outdoors can be harder to handle in this age of masking, Hildrew says. In the past, you may have been able to filter it out and hear what someone is saying by reading their lips, he says. But now with masks, thats taken away.

The fix: If you are wearing your hearing aid full-time and are still annoyed by background noise because it prevents you from concentrating, see your audiologist. They can activate the devices directional microphone, which reduces sensitivity to sound behind you to allow you to focus on hearing whats in front of you.

But if youre bothered by background noise because it makes it hard to hear othersfor example, a co-worker, or your family at a restaurantthen a remote microphone is a better option, Palmer says. This is a small microphone clipped to the lapel of the person you want to hear, which sends a wireless signal to your hearing aids. It can be found in many newer hearing aids, or added to an older version.

What Is That Screeching

Many hearing aid users talk about the embarrassment caused when their;hearing aid makes a high-pitched screeching noise. In fact we had someone in recently to one of our hearing aid Centres in Dublin with the problem. Professionals call the sound Feedback and manufacturers have dedicated a lot of resources to try and eliminate it.;Not only is it embarrassing and annoying, but it also interferes with the benefit that the hearing aids should provide. Modern hearing aids don’t suffer with the problem nearly as much as they once did. However, even with the best it can still occur occassionally but there are specific reasons why. First off let’s talk about what feedback is.;

Hearing Aid Is Not Producing Enough Sound

  • Examine the hearing aid from all angles. Earwax may have gotten into the microphone hole or sound exit. Any debris should be removed with care.
  • Check to see that your hearing aid is operational. Hearing aids are typically activated by shutting the battery door on the device. If the battery door is difficult to close, the battery is likely upside down. Remove the battery, flip it over, and try to re-insert it again. The door will close easily if it is properly installed.
  • Increase the volume by using your remote control or by pressing the volume button on your hearing aid. To make sure the volume control wheel is fully turned on, move the wheel up and down a couple of times on the steering wheel.
  • In order to switch between the many programs or memories you have, push the button to alter the settings if you have one and listen for several minutes to see if it makes a difference. If not, you should try another setting.
  • Replace the battery with a new one. If you have a hearing aid battery tester, use it to check the voltage of the old battery to ensure it is dead before activating a new battery by removing the sticker off the old battery.
  • Consider whether or not the hearing device needs repair. Further assistance might be obtained by contacting hearing care specialists. When it comes to troubleshooting and hearing aid repair, they may provide walk-in hours or same-day appointments.
