Important Hearing Aid Terms Defined

Important Hearing Aid Terms Defined

You’ve known you’ve had a hearing loss for quite some time now and you finally get up the nerve to get your hearing tested. They tell you that you need a hearing aid and you cant help but think, Why did this have to happen to me?? Then they start telling you about hearing aids and use tons of terminology that just goes right over your head. Dont they know that you are in shock??! How can you make an informed decision about anything when you dont even know what they are talking about!?

There are hundreds of different hearing aids. It can be a very complicated world of technilogical terms. Sometimes those of us that work with hearing aids all the time can forget just how foreign they can sound to you. To make matters worse, the manufacturers like to call things different names, so they sound like something different. No wonder there’s so much confusion!

I am going to try to unravel some of the mystery for you. When you get down to it, there are really only a few terms you need to understand. These features are the ones that really matter, and the model or the style of the hearing aid.

There are seven primary styles of hearing aids: ITE, Half Shell, ITC, Mini Canal, CIC, BTE, and Open Ear.

In the Ear (ITE) ITE hearing aids are the largest custom style of hearing aid, filling the bowl of your ear, and can have the most power and features available for in the ear hearing aids.

Half Shell (HS) The Half Shell is a custom hearing aid that only fills about half the bowl of your ear. They are able to have a good deal of power and features, use a smaller battery, but are more cosmetically appealing.

In the Canal (ITC) The next smallest size is the custom ITC hearing aid. Harder to see than the larger hearing aids, but also not able to have as much power or as many features.

Mini Canal (MC) Smaller than the ITC hearing aid, the custom mini canal uses a smaller battery and has even less power available. Features can also be more limited.

Completely in the Canal (CIC) The CIC is the smallest custom in the ear hearing aid and very popular due to its cosmetic appeal and ease of use. There are usually no manual controls on a CIC, telephone usage is often better because they are less likely to whistle. Lack of power is the main reason people cannot use this style of hearing aid, though a small ear canal may keep you from being able to wear one also.

Behind the Ear (BTE) A BTE hearing aid sits behind your ear and is connected to your ear by a tube with an earmold attached. BTE hearing aids have the most power and features available.

Open Ear (OE) and Receiver in Canal (RIC) This hearing aid is a fairly new style of BTE made available in recent years and are much smaller then a traditional BTE. They are meant primarily for high frequency hearing loss. The hearing aid is connected to your ear by a very thin tube or wire with a small earbud on the tip. They are called Open Ear because they leave the ear canal less blocked than other styles of hearing aid.

Important Features:

Directional Microphones – These are available on most BTE, OE, ITE, Half Shell, and ITC styles of hearing aids. They are the best feature you can have on your hearing aid for hearing in noisy places, such as restaurants. This means they reduce all the sounds that are behind you so that it doesnt get in the way of sounds that are in front of you. Directional microphones can be automatic meaning that the hearing aid automatically decides when to turn them on once the sound level in the room gets too loud. Some are also be adaptive, which means they can follow moving sounds, or reduce several different sounds at the same time.

Noise Reduction – Noise reduction doesn’t really reduce noise, it reduces amplification in the frequencies where there is noise and no speech. If there is a fan running in the background, the hearing aid will not amplify it as much as it will speech. When the hearing aid finds both speech and noise at a frequency, you still get both. More advanced the hearing aids manage noise better by breaking the frequencies up into smaller pieces.

Memories – There are two types of memories available on a hearing aid, manual and automatic. Many hearing aids have a push button that allows you to have different settings (memories) for different situations such as quiet places, noisy places, and music or telephone. The hearing aid beeps when you push the button to let you know which memory you are using. Advanced hearing aids can have memories that are automatic. Instead of pushing a button, the hearing aid does it for you! Some hearing aids have a combination of both.

Feedback Cancellation – Feedback (or that annoying whistling sound) is the number one compaint people have about hearing aids. Most hearing aid wearers experience feedback when they put their hand over their ear, or use the phone. Feedback Cancellation will take down the amount of feedback (whistling) that you hear.

Bands / Channels – Bands are what we use to adjust the volume in a hearing aid. More bands means more control when we program the hearing aid to your hearing loss.

Channels are used to adjust the part of the hearing aid that keeps the sound from getting too loud. Channels can also refer to the hearing aid noise reduction system. For noise reduction, more channels is definitely better because the hearing aid can break the sound up into smaller pieces and isolate noise from speech.

These are the main things you need to understand about your hearing aid. If you really want the best hearing aid for you I recommend you focus on telling the hearing professional what benefits you want from your hearing aid. Tell them what frustrates you most and give them a better picture of how they can help you. Their goal is to help you hear better, and when that happens, everyone wins.

Help answer the question about Hearing Aids

Where can I get money for some hearing aids?
I have a high tone hearing loss and have to read lips alot. Hearing aids are around $5000 or more and I cannot afford them. Insurance does not cover them either. Does anyone have any real suggestions? I am already working 60+ hours a week so another job is not an option. Thankyou.

    i’ve got 70% loss in left ear and 68% in right ear so yeah.. any tips for me ( i dont want to wear them at school). I will get bullied

  2. stevoph7 says:

    There is NO best trade or model since everyone’s hearing loss is different and the age onset is different. And digital and analog hearing aids are DIFFERENT. I prefer the analog so I have Oitcon.

  3. bestamerica says:

    i have 2 normal hearing aids and love it,,,
    i dont like digital hearing aids because of different sound

  4. HS Kid says:

    Check with the Hearing Loss Association of America (www.hearingloss.org), which also has a state organization in Florida with local chapters. That's one place to look.

    Assuming you're in Florida (home of WDW), check with these organizations:

    North Florida Lions Hearing Aid Bank
    Lion William E. "Bill" Pace
    E-mail: wepace72@aol.com

    Northeast Florida Lions Hearing Aid Bank
    Lion Shirley Shuler
    E-mail: mercurymomma@msn.com
    Fax: 352-372-7915

    Good luck!

    Programs for private use are already on the web – and for free – and even more sophisticated than the “audiologist ones. They´re just a mythical branch who want to make too much money with haring aids that aren´t even worth 50 $.

  6. Starship Pain says:

    Saw some tv ads, the former 6 million dollar man, Lee Majors, old tv show.
    He advertises one. "For a 30 day trial, $14.95"

    The appliance cost about $200 range.

    If your hearing isn't too bad then you can be fit with hearing aids that are called "open fit". This leaves your ear canal as open as possible- this combined with the amplification have helped a lot of people who suffer from tinnitus.

    A GOOD QUALITY hearing aid is not cheap. You should expect to pay anywhere from 1200-2800 PER AID, and it can be more depending on where you live. But, keep in mind these are an investment that should help you for AT LEAST 5 years. Some insurances will cover a small portion of your hearing aids, but most don't. There is something called "Care Credit" that some audiologists use to help their patients finance their hearing aids…its similar to if you were to buy a home appliance and they offer you no interest for however many months.

    But no matter what, you need to get a thorough evaluation by an audiologist and get their best recommendation. Don't go to Beltone, Walmart, Amplifone, Nu Ear, Miracle Ear, or any large chain…their first concern is making commission and hoping that you don't return your aids within the trial period. Go to a licensed audiologist who cares about your hearing over the sale.

    Hi! I’m from Germany and I’m learning the job of a hearing aid audiologist.

    For the people who want to get hearing aids:
    Just go to a hearing aid audiologist. You just will have problems with the hearing aid if you get it from eBay or other sites…

    The first problem would be that the h.a. isn’t matched with your hearing loss and you won’t be able to program it, because you haven’t the right software and I think you don’t exactly know how much amplification you need on which frequences…

  9. Welshkiteflyer says:

    Unless you cna get the digital aid programmed for you dont buy from ebay. these aids need and must be programmed to your prescription

  10. puertosio says:

    Excuse me Madam. Which one do you use? Which trademake? Can you recommend something?
    I´ll grateful you. Thank you.

  11. pepicasso says:

    If do you live in U.S.A. Go to a Sears Store to the Hearing Aid Department, they have the best, for you . If not, I’ll recommend a Hearing aid of German Trade. Those are the best !!!. Good Look !!!.

    Viewing speech from the perspective of consonant and vowel is not very useful as the majority of the languages in the world are not based on this. The more accurate modeling of human voice is LPC (Linear Predictive Coding). From wikipedia (http://en.wikipedia.org/wiki/Linear_predictive_coding):

    "LPC starts with the assumption that a speech signal is produced by a buzzer at the end of a tube (voiced sounds), with occasional added hissing and popping sounds (sibilants and plosive sounds). Although apparently crude, this model is actually a close approximation to the reality of speech production. The glottis (the space between the vocal folds) produces the buzz, which is characterized by its intensity (loudness) and frequency (pitch). The vocal tract (the throat and mouth) forms the tube, which is characterized by its resonances, which give rise to formants, or enhanced frequency bands in the sound produced. Hisses and pops are generated by the action of the tongue, lips and throat during sibilants and plosives."

    The latest technology in hearing aids is digital processing. Improving speech intelligibility is just one domain. This is called "Digital Speech Enhancement (DSE). These systems act to increase the relative intensity of some segments of speech. Current DSE processing identifies and enhances speech based either on temporal, or more recently, spectral content. DSE in hearing aids is still relatively new, and its effectiveness is largely unknown".

    Other digital technology to improve hearing aids are:
    1. enhanced gain control, either automatic or intelligent
    2. feedback reduction
    3. noise reduction
    4. synthetic directional microphone
    5. custom shaping of emphasis filters

    On noise reduction Sony's latest digital technology has artificial intelligence. See http://www.wired.com/reviews/product/sony_mdr_nc500d

    I found a few links that may help you. Personally, we sat our grandfather down and explained that if he didn't go in for testing grandma was going to stop listening to HIM until he did….but grandpa was really a stubborn ornery sort of person and I wouldn't recommend that approach for many people. The links are probably more appropriate for your situation. :)

    It may help if you could get him to discuss why he doesn't want a hearing aid. They make almost invisible ones cheaper now if he's vain about it. Perhaps he doesn't want to spend the money or doesn't have insurance that would cover it. In the end there may be nothing that will convince him to get one, but good luck with your efforts hun.

    FMs AND HEARING AIDS ARE TWO DIFFERENT THINGS

    FM systems and assistive listening devices (ALDs) are not just used in theaters and churches anymore. It is your right under the Americans with Disabilities Act (ADA) to access needed modifications such as a taper recorder, preferential seating, a note taker or FM system.

    PLEASE NOTE THAT BILATERAL HEARING AIDS IMPROVE LOCALIZATION AND AMPLIFIES SOUNDS… INCLUDING SOUNDS IN SPECIFIC FREQUENCIES BASED ON YOUR INDIVIDUAL AUDIOGRAM.
    FM SYSTEMS JUST AMPLIFIES THE SPEAKERS VOICE WHICH REDUCES THE BACKGROUND NOISE.

    There are several types of FM systems that can be used in the classroom. FM systems are composed of a FM transmitter and a receiver.

    The FM transmitter or the microphone and its components are used by your professors. The idea is to increase the speech signal and to decrease the background or ambient noise that your hearing aids may pick up.

    The FM receiver can be an ear level receiver such as hearing aid audio boots. A boot is a small sleeve that fits over the end of a BTE hearing aid. The boot inserts the audio signal into the hearing aids' Direct Audio Input (DAI) interface. Not all BTE hearing aids have an audio boot interface.
    Other receivers include: headphones/ear buds (typically for children with CAPD or ADD), a desktop speaker or a sound field system located around the classroom (everyone benefits from this).

    Depending on the type you buy, FMs can be fairly inexpensive to purchase. Here's just one of many links:

    IMPOSSIBLE!

    once the hair cells are damaged they are damaged. there is no magical-medicinal cure for a sensory/ neural hearing loss.

    buck up and get your self some hearing aids. if you have a high frequency loss. make sure they have directional microphones and at the very least 8 channels so the audiologist has greater programming ease.

    I would check with the company who made the hearing aid first before trying it.
