High Tech Hearing Aids

If you haven’t experienced the sticker shock of buying a pair of hearing aids (most people buy two, one for each ear), you will when you visit your hearing health professional. These little dynamos are packed with circuits and chips and other state of the art technology. These are not grampas’ hearing aids. Oh, and they’re pricey.

Since you’re going to spend quite a bit, you should make sure you get the most for your hearing dollar so before you even set up an appointment for a hearing screen, consider the four features any consumer should look for when purchasing a hearing instrument.

Feature #1: Hearing Comfort

Consider that your hearing aids are with you all day, all night – all the time. So, you want a device that provides as natural a sound as possible. Lower-priced models often deliver a tinny sound. Higher priced models can be adjusted for your particular hearing needs, providing a more natural sound.

Behind-the-ear (BTE) hearing aids provide an even more natural hearing experience because the speaker rests outside the ear canal, allowing your natural hearing to do what it can before getting a boost from a BTE.

Try several different devices before finally deciding on which device to go with. Oh, and a 30-day exchange policy is always comforting when writing out a big check. If you aren’t happy, the hearing aid dispenser works with you until you are happy.

Feature #2: Wearing Comfort

Again, your hearing aids are with you all of the time and the last thing you need is ear fatigue. So, which units are most comfortable and still meet your hearing needs?

BTEs are lightweight. But if you wear glasses, you may not want to fiddle with a hearing device and eyeglass stems all day long.

Completely in the ear (CIC) units are invisible to all, so if you’re going for a discreet profile, consider a CIC. However, many people complain of stuffiness and are annoyed that their own voices sound different. Sure your voice sounds different. Plug your ears and talk. You sound different. So, CICs may take some getting used to but for consumers looking for a low profile, the adjustment period is only a week or two before the sounds you hear are natural.

Finally, in the canal (ITC) units rest partly in the canal but don’t actually seal up the ear canal the way CICs do. For many, ITCs are a good compromise between the CIC and BTE. That’s why it’s important to work with a hearing professional to find the right device to suit your wearing and hearing preferences.

Feature #3: Automated Convenience

There are hearing aids that’ll do everything but pick up the grandkids for you. Better units come with features like automated feedback suppression so your hearing aid doesn’t screech like a banshee when you talk on the phone.

Automated volume control “reads” changing listening environments and adjusts the hearing aid’s amplifier to suit the “ambient sound” conditions – noisy restaurant or quiet walk in the woods. Automated volume comes standard on mid- and higher-priced models.

Other features to consider? An omni-directional microphone that’s able to lessen background noise while boosting the volume of the conversation taking place right in front of you. Automated noise cancellation that eliminates light wind gusts that sound like a Force 5 nor’easter using lower cost units. There are units that tell you when the battery is running low and, today’s wireless connectivity has produced hearing aids that act as wireless phones, MP3 and other wireless devices – seamlessly.

It’s important to focus on the features you’ll use. If you don’t plan to kayak down the Colorado, why are you buying a waterproof hearing aid?

Feature #4: Price

Of course price, but actually this should be your last consideration, not your first. Yes, hearing aids – good ones – are expensive but can you put a price on a grandchild’s giggle or the sound of the waves in the distance. Hearing aids are “quality-of-life-products.” You don’t have to buy the most expensive, but as with anything, you get what you pay for so the more you pay, the more you get. Your choice.

On final note: avoid those $14.95 ear amps you see on TV. They’re dangerous and can actually further damage your already sensitive hearing mechanism.

Be a smart consumer and spend what you can. The money will be forgotten in a couple of days. The benefits of better hearing last a lifetime.

The basic components of a contemporary headset includes a microphone, an amplifier, a receiver and a power source.

A microphone is a transducer that converts the sound signal into electrical energy. The amplifier is a transformer that increases the amplitude of the electrical signal that is sent to the receiver. The receiver then changes the electrical signal modified again in sound energy that goes into the ear.

A variety of microphones, amplifiers and receivers are used, depending on the type and degree of hearing loss. The American National Standard Specification specifies the characteristics of hearing aid electroacoustic evidence that the manufacturer must conduct and publish for each hearing aid before the instrument is shipped.1 The law establishes the permitted level for the audiologist can perform the same tests to verify compliance an instrument against the specification.

Currently used headset microphones are mainly electrical appliances that have good performance in a linear frequency range of 50-6000 Hz This range can be modified to be more appropriate for certain hearing loss.

Directional microphones that have been developed so you can vary the extent and direction of the sound source in relation to the microphone. They can reduce the sounds from the back of a hearing aid user in comparison with the sounds from the front of up to 15 dB. This change can improve the signal to noise of the listener, and therefore the understanding of speech in the presence of noise.

Headphones amplifiers processors are mainly composed of transistors that are built on an integrated circuit. These transistors a current source and serve a variety of functions. In these transistors, the main function of the amplifier is to increase the power of the electrical signal by the microphone.

Normally, the headphones are 2 or more stages of amplification. The first stage is the preamplifier, which is at the level of the microphone. The preamplifier helps amplify the original input signal. At this level, the gain is relatively low.

Most of amplification is provided by the power amplifier. These amplifiers are written in a particular class. The most common are known as Class A, Class B and Class D Distinguished by its energy consumption, profit, production and capacity.

Each amplifier can be modified to limit the maximum power of the headset. Linear gain, the amplifier can be limited by cutting peak. This occurs when the electrical signal exceeds the maximum output of some components of the hearing aid circuit. Limiting such causes various forms of distortion that have been found to reduce the subjective quality and intelligibility of speech.

A hearing aid that has some kind of level-dependent non-linear signal processing is called a hearing aid. Most of the non-linear hearing aids to reduce the input gain and output levels increase.

Nonlinear hearing aids are designed to amplify a wide range of sounds that are audible to the hearing without listening uncomfortably high. These grants often use some type of compression circuit that reduces the gain of the instrument, either when the device at the entrance or exit of the device exceeds a predetermined level. This process results in an amplification comfortable and prevents the user from saturating the headset.

Compression can provide hearing aids amplify the voice components that are essential to reduce the intelligibility and impulsivity or high-level sounds often cause discomfort.

The headset is a receiver transducer output and handles more power than a microphone. Receivers in the headphones are very small due to considerations of cosmetics.

In general, the bigger receivers can provide larger output signals. Therefore, small auditory receptor may be taxed to their capacity.

The receiver also must be chosen to match your amp. A mismatch in the design and production to produce distortion increases.

Due to the open receiver in the external ear canal, which is vulnerable to damage caused by debris in the ear canal and aid declined. Manufacturers claim that about 40% of hearing aids have returned to service damage or blockage of the receiver.

For decades, best hearing aids used the same analog technology as radio and television. But when the digital revolution came along, it made sense that you would see a revolution in hearing aid technology in the form of new sophisticated hearing aids as well. The outcome is that when you are shopping for a new hearing aid, you now have a choice. Of course, the digital alterative might be more expensive. But at the same time, there are some real advantages to going digital in this area of your life like we all have in so many other ways.

One reason that new technology like modern hearing aids do come with a high price tag at first is that the research and development effort that goes on behind the scenes when a big breakthrough is brought to market is expensive. In some cases, new designs in hearing aid technology might take years to develop and test and all of that research has to be paid for. So when the hearing aid hits the market, much of that initial cost is there to pay off the tab from all the work it took to discover and test that technology.

For most of us, when we have made the change to digital technology in other areas of our lives, we are glad we did. That will be true when you make the switch to digital design in your hearing aid as the technology becomes more available to the rest of us. For one thing, a word that goes hand in hand with digital technology is miniaturization. So once we get used to hearing aids that take advantage of miniaturization, your hearing aid will get smaller so it is not as cumbersome to wear and not as noticeable as well.

Part of the big expense in developing and distributing these new designs in hearing aid research is that digital technology allows scientists to imbed computer chips right into your hearing aid. This will make your hearing aid a “smart hearing aid” that is able to make small adjustments and notice things about the atmosphere, noise level and other factors that can affect your ability to hear and it can make adjustments to the hearing aid settings to compensate for you.

In this way, the hearing aid of the future will be smart and do a much better job of working in any setting because of digital technology. And that technology isn’t centuries away, it is here right now and soon to become part of your life.

Of course, the price barrier in digital technology in the best hearing aid industry will almost certainly come down. Just as has happened in every other area of technology, once competition gets into the market and what might be an “exotic” feature in hearing aids becomes more common, the price will come down and make it possible for everyone to afford all of these nice features. So it might just be a waiting game to let the market catch up with the technology before you make the transition to a digital answer to your hearing loss correction technology.
