How Do Hearing Aids Work?

Hearing aids have been around for decades. The first hearing devices were just conical devices that you held up to your ear so that a person could speak into them. This would funnel the sound directly into your ear. Now there are more impressive types of hearing aids, working with a higher degree of technology. So, in modern times, how do hearing aids work?

Hearing aids use small microphones to make a soft sound louder. They do this by using a small microphone. This device will receive the sound that comes in and convert it to an electrical or digital signal and send that data to a speaker where it is turned into sound once again. Settings for these microphones take into account the degree of a person's hearing loss and their usual environment. Environment here refers to how much and what kind of noise you are usually around. Are you usually near high frequency noises? If so, do you need to hear them? Do you function mainly in a quiet conversational environment? All these questions will help the audiologist adjust the settings on your hearing aid. This is only part of the answer to how do hearing aids work.

There are three basic types of technology that receive and convert the signals in hearing aids these days. The least advanced is the analog adjustable hearing aid, and it costs less than the other two types. This type of hearing aid is adjustable by your audiologist for volume and other specifications. The factory will then custom make it for you. You can control the volume or it will be controlled automatically.

Another type of circuitry found in hearing aids is called analog programmable. These are somewhat better than the analog adjustable because they can be programmed by using a computer. The audiologist sets different programs of sound capture and transmission for different listening situations. The user can select which program to use at any given time by using a remote control.

Digital programmable hearing aids are the most advanced and of course, the most expensive. For years they were impossible and then they were impractical because they couldn't be made small enough. That is no longer the case.

So, how do these hearing aids work? Their circuitry contains a feature called DSP, or Digital Sound Processing. They utilize a computer chip to analyze and process the sound data before it is amplified to the ear. It does this by using billions of digital number codes to identify and classify sounds to give them the correct settings. This digital data is then converted into sound and sent on to the ear. The digital hearing aid also has the capability of detecting and eliminating feedback by identifying its frequencies. These hearing aids work automatically with little adjustment from the wearer.

Hearing aids have come a long way in a short time. People who can want to hear better have many options now. And if you find yourself asking, "How do hearing aids work," the answer these days is technology.

The Importance of Getting the Best Hearing Aid

Do you remember when you were young and you connected two big paper or plastic cups to a length of string, letting your friend hold one while you held the other? This hearing experiment was well-known by many generations, often as an attempt to pretend to use a telephone. Well, it also was one of the inspirations for one of the early types of hearing aids. The hearing device was called an ear trumpet, helpful but certainly not the best hearing aid. The development of hearing aids has come a long way since then!

A medical term for hearing loss is 'otosclerosis'. Hearing is defined as the process of perceiving sounds.

Having the best hearing aid can help you get past the attitude barriers of others who don't seem to understand your challenges. It opens the door for better, more accurate communication. It's no fun to be made fun of because your hearing aid or your hearing impairment won't allow you to properly interpret the words directed to you or around you. It can be especially devastating to a child. The physical handicap is far from being the only challenge to overcome. A hearing aid can help give a hearing-challenged child courage and ease their stress levels tremendously.

Although sign language and lip reading are important and helpful to many people with hearing loss, not every hearing impaired person has learned these tools and these tools aren't always the best for every situation.

When you realize the need for a hearing aid, there are several things to consider. The amount of loss suffered, whether you have loss in both ears or just one and how much in each ear, the fit to your unique ear shape, the cost, the service fees for the equipment, batteries and their availability, location of a hearing aid provider, your lifestyle, and the testing to determine your needs.

If you're a parent, you'll want more than just a test by the school nurse to determine the extent of hearing loss and the proper needs for your child. There are more choices available for children and more attractive aids created just for their interests. Purchasing the best aid now may make a difference in how their hearing loss progresses.

Some of the top hearing companies in the market are Starkey, Siemens, Beltone, Phonak, Rexton, Sonic Innovations, Unitron, Widex, and Sebotek. Just about everyone has heard about the popular Miracle Ear! You can find ads in magazines geared towards the interests of the elderly, check the flyers in the doctor's offices, and ask around.

You might be surprised who wears a hearing aid these days! Although the elderly are the first in thought when hearing aids come to mind, anyone at any age can develop a need for a hearing aid. Just asking someone to give you an example of their experience can lead you to your choice of the best hearing aid for you.

The best hearing aids will come with a few extras, like a good warranty, extra batteries, the storage case, instructions, important numbers to call for service centers, and the ear wax cleaning tool.

What You Need to Know About to Compare Hearing Aids

You have just realized you have hearing loss. Or, you have recently gained the ability to do something about it. Now you have to sort through all the different styles, models, and manufacturers to find the right ones for you. You can no doubt get some help from your audiologist, but if you want to be an informed consumer, you will want to learn to compare hearing aids for yourself.

When you do compare hearing aids, the first question is whether you want to get analog or digital hearing aids. Analog are the least expensive by far. These hearing aids simply receive a signal from a microphone, amplify it, and send the louder sound on to the ear. It's as simple as that.

There is a middle ground between analog and digital. These are sometimes called digital programmable, although they are not 100 percent digital, or they are called analog programmable. The idea here is that it is indeed an analog hearing aid. It just has the advantage of a certain amount of customization in programming through the use of computer software. This can give you a variety of settings you can manually switch to accommodate your listening preferences in different listening situations. The settings can be changed by reprogramming at any time. When you compare hearing aids,these are more expensive than the regular analog ones, but less so than fully digital ones.

Fully digital hearing aids are the most expensive, and when you compare hearing aids you will find many reasons why this is so. The difference in sound quality is like the difference you get when you go to digital music recordings from old fashioned record albums. This is done through DSP, or digital signal processing.

There are differences in the programming as well. One thing to notice when you compare hearing aids is how many channels or bands it has. This is important because if your hearing loss is not the same for all frequencies, you will want different frequencies adjusted differently. Some people may only need a couple of bands while others may need several.

It is also nice to know if a hearing aid has directional microphones. If it does, there are two microphones that emphasize sounds in front of you rather than behind you. Some models have a switch so that you can turn this feature on and off.

Another way to compare hearing aids is by taking into account how many preset programs there are to switch between. You might want different programs for different aspects of your life, like home and work environments, and the surroundings at your favorite free time activities.

Compare hearing aids by noting which ones are "smart" hearing aids. These have the capability to learn your preferences by the way you use them when you get them. These are easy to operate because, after awhile, the hearing aid automatically sets itself the way you usually set it yourself. Other features are reduced feedback and wind noise, and the ability to use the device with phones or even mobile phones.

In the end, you will probably talk it over with your audiologist before you make your final decision. It's nice to go in to that talk armed with some facts of your own. That is why it's in your best interest to compare hearing aids yourself.

What You Should Know About Digital Hearing Aids

There are digital hearing aids available without a doctor's prescription or testing. Some of the aids you can buy that go in the ear canal are digi-ears, which range from $300 to $700 and have various additions. They're versatile to fit either ear, so if you bought two of the same type, you wouldn't have to worry about which aid would fit each ear if you got confused.

Many different digital hearing aids are available. Some of them include a two channel value aid, which is a low cost aid, a mid-level four channel aid that provides feedback reduction and a speech amplifier, and the best level (also a four channel aid), which offers echo suppression and layered noise reduction. All of these aids come with a wax remover. (Wax seems to be a problem for hearing aid wearers and must be kept to a minimum for the best reception.)

You may want a carrying case for your digital hearing aid, to keep it safe by the bedside or in the nightstand while you sleep. The carrying case can help protect it from insects or dust or even a naughty cat who likes to knock things off furniture! Keeping your digital aid clean and dry is important for proper function and long-lasting use.

Digital aids use microprocessors to process sound for you to hear and should adjust volume according to sound levels. There are different frequency levels an aid must allow for; each level will have its own amount of hearing loss. This makes the correct purchase of an aid even more important. An ill fit, improper adjustment, or neglect to the proper levels you will need help with are reasons you should be properly tested and should use a professional to help you choose the right aid for you. Your lifestyle and budget are, of course, two other important factors to consider. You'll want to work with a quality hearing aid supplier, purchase an aid made by a reputable company, and go through the proper medical channels to help you make the best decision.

Almost any company that sells hearing aids will now have digital aids available for purchase. Digital aids can reduce or eliminate feedback while the person wears them. They have gain processing, which reduces microphone noise and environmental sounds. Speech recognition is more accurate with less annoying interruptions to filter through to hear what someone is saying. If you've ever held a large seashell up to your ear, you should recall the loud white noise it makes.

Suppose you had to walk around every day with that noise in your ear, making it hard to decipher what anyone is trying to tell you at any time of the day or night. Digital aids have been improved to overcome that type of obstacle. They have been improved to help cut down on the equipment a person used to be burdened with when wearing a hearing aid. Digital aids are more easily adjusted with more built-in capabilities than ever before. They even include signal generators to increase accuracy with your fittings.

What Does Siemens Hearing Aids Have to Offer?

Siemens, sometimes misspelled as Seimens, is in the business of hearing aids. Having been in the business for more than 100 years (since 1847), it is an unusual name and has most likely suffered through just as many years of spelling mishaps! But while the spelling may confuse you, their hearing aids should not. They have representatives specially trained to help you determine what is best for your needs.

The Siemens company understands how hearing loss can occur due to medication, ear infections gone out of control, head injuries, childhood diseases, and birth defects. Loud noises are often taken lightly and grossly miscalculated risks are taken which wear on a person's ability to hear properly until one day, they realize it's time for a hearing aid. Siemens knows the importance of getting evaluated for the proper aid and proper fit, and also the importance of taking care of the needs of children with hearing problems.

Children benefit from Siemens BTE hearing aids because they are more durable. Anyone who has an active child knows how important it is that anything the child must use has to stand up to the rugged lifestyles. Your child shouldn't be missing out on their chance to enjoy life simply because of limitations imposed by hearing aids that won't meet their needs properly.

Are you a frequent traveler? Ask your Siemens (also known in error as Seimens) representative about locations you can stop by for service to your hearing aid. Make a note of the locations for future reference and keep it with your important paperwork. They're very widespread, operating in Africa, America, the Middle East, Asia, Australia, and Europe.

Is your hearing loss conductive? If so, you'll need an aid that has the primary function of sending sound through the middle or outer ear. Your hearing should be restored simply by amplified aids, so the analog aids should work well for you. If your hearing loss is associated with aging or has other causes, restoring your hearing could be a bit more complicated. But whatever the type of hearing loss, Siemens (not Seimens) is sure to have the right hearing aid to improve your life.

Siemens offers value Digital, Basic Digital, and Ultimate Digital choices. Their aids offer AutoPhone features, which is a huge step for hearing aid users who know how inconvenient it can be to try to use a telephone with a hearing aid of the past. The Siemen product families include Triano, Prisma 2, Music Pro, Phoenix Pro. Just the Prisma 2 basic BTE model can run from $1700 and up.

Siemens (Seimens) participates at Trade shows and educational symposiums. They can provide you with an event calendar, support program, website service, and marketing services. Whether you wish to buy a hearing aid, sell one, or just have a program at your school or business about hearing aids and hearing loss, this is a company that should be able to help you out. Some of their charity project partners include the Pangea Foundation, the Line of Safety civic association, and the Children to Children project.

Some Choice in BTE Hearing Aids

Many of the excellent hearing aids come in a variety of styles including BTE (behind the ear), ITE (in the ear), ITC (in the canal), MC (mini canal), and CIC (completely in the canal). Some manufacturers, though, make special models that are specifically designed with the usual user of BTE hearing aids in mind.

Oticon, for instance, makes the Sumo DM with plenty of power to amplify sound for those with greater hearing loss. With the increased ability to amplify comes the possibility of voices that don't sound weak or distorted. Its design also conserves battery life, and even when the batteries do start to run down, the Sumo DM's performance doesn't suffer. This is a good practical choice for the BTE hearing aid wearer with significant hearing loss.

For a high-tech solution, try the Widex Senso BTE hearing aids. These have all the fancy features. They are fully digital. They process sound at an extremely fast rate, which is not true for all digital models. They process it in three bands. They analyze the signal, regulate it within each frequency, process the signal and send it through to the speakers.

These BTE hearing aids separate speech from noise and put the emphasis on the speech sounds. Also, they have a great system for eliminating recruitment. This is a phenomenon in people with hearing loss where at first they can't hear you at all, and then you speak just a little louder and suddenly they feel as if you're shouting at them.

These BTE hearing aids are also programmed to deal with feedback. They come with directional microphones on each hearing aid. They reduce the noises that are more constant in your environment, like the hum of a refrigerator. And, these BTE hearing aids are also available in special models that have more power for the people with more profound hearing loss.

One type of BTE hearing aid that is made by several manufacturers is the open ear BTE aid. These are very lightweight and comfortable. The ear mold often comes in designer colors. The aids are equipped with extremely thin tubing for their ear hooks. The actual aid compartment itself that sits behind the ear may be so small and light that it's barely noticeable. For example, the Siemens Prisma BTE hearing aids weigh only two grams, but still have two microphones and a couple of memories that you can switch by pushing a button. The Starkey Aries BTE hearing aids are also extremely small.

The open ear hearing aids have the added bonus of not blocking your ears. Many people are very uncomfortable having their ears shut off the way they are with most hearing aids. With the open ear hearing aid the ear has room to breathe, so to speak. Many also come with nanocoating. This is a covering substance that repels foreign matter such as sweat, dirt, and water.

Each kind of hearing aid is advantageous for someone. If you decide that BTE hearing aids are your best decision, explore the options carefully. There are many choices available within that category.

How Low Cost Hearing Aids Can Change Your Life

Insurance covers hearing devices for very few people. Most people with hearing loss are on their own when it comes to getting help. Many can't afford the exorbitant prices the manufacturers charge for their hearing aids. Without help they may not see much hope of being able to hear adequately. If you are one of these people, there could be a solution. Low cost hearing aids could change your life.

With a little help from your computer, you can go on the internet and find offers from sellers other than the manufacturers on name brand hearing devices. These sellers can save you a lot of money by offering low cost hearing aids that are exactly the same as the kind you are looking for. Because they do this, you may be able to afford a more sophisticated and technologically advanced set of hearing aids than you could have otherwise gotten.

Low cost hearing aids can let you hear voices clearly again without the distraction of amplifying every noise in the background. Through data learning functions, the hearing aids can adapt to your own style of listening pleasure. This is technology that you may not have been able to afford without low cost hearing aids.

No longer will you be bothered by noises that are behind you if your low cost hearing aids come with directional microphones. You will be able to hear clearly whatever is in front of you. All you have to do is face the sound you want to hear. Then, if you want all the sound in the room to be available to you, many models have a switch so that you can just turn the directionality off.

If you're like many people who can't hear certain frequencies, like the high-pitched sounds of children's voices, then you will be glad to know that there are low cost hearing aids available with several channels. These channels or frequency bands will make it easy for your hearing aids to be adjusted to your specific hearing needs.

People who suffer from recruitment, a condition where sounds go from being too quiet to immediately being too loud, will find that certain low cost hearing aids come equipped with a feature that reduces this problem. Feedback can also be controlled.

Memory presets are available with many hearing aids. If you find low cost hearing aids that are identical to the higher priced manufacturers' aids, your hearing aid might come with several memories to accommodate different specific listening environments.

Being unable to use the telephone is very disabling these days. So much of what we do depends on the phone. Devices that allow people with hearing aids to listen on a phone are available on many low cost hearing aids. Some of them even can be used with cell phones.

If you get a hearing aid that is identical to a manufacturer's hearing aid, then a low cost hearing aid will not be something that will be thought of as lesser than. In fact, low cost hearing aids, when chosen wisely, can change your life.

What to Look for in Inexpensive Hearing Aids

With hearing aids costing thousands of dollars each in some cases, it's easy to become discouraged. It's easy to give up and say to yourself that you'll just have to learn to live with not being able to hear. Maybe you can learn to lip read, you think. But, what if you can find hearing aids that you can afford? Maybe you can. You just need to know what to look for in inexpensive hearing aids.

There are some devices that send the sound to your ear with very little processing except a bit of amplification. Some of these are not even sold as hearing aids, but are sold to hunters who want to be able to hear wildlife noises very well. These are rightfully called listening devices. They do not meet FDA guidelines that describe what constitutes a hearing aid. At prices usually under $20 each, they claim to be inexpensive hearing aids, but they are not considered by most to be hearing aids at all.

Watch out for companies that insist on you signing a waiver of medical care before they will send you your hearing aids. These companies do not expect to go through a hearing professional. If that's what you want, then so be it. Just make sure you are aware of the consequences of this decision. If you have a medical condition that is causing your hearing loss, it might be serious and it might be better if you had it checked out. But, that is your call. Maybe this is the way you want to go about getting inexpensive hearing aids.

Your best bet is to look for deals on well-known brands and models of hearing aids. These can be found at better prices than the manufacturer offers, if you look on the internet. Just make sure you are comparing the exact same brand names and models of hearing aids to the same inexpensive hearing aids you have found. Also, make sure that they are new and have a warranty. Find out about trial periods and return policies. If you go through your ENT doctor, you will find that you will be given a rather long trial period. At any time during this period, you can bring the hearing aids back for a full refund minus a very small restocking fee. The same policy does not go for all sellers, especially internet sellers.

Another thing to look for is how the inexpensive hearing aids are fitted, both in physical conformity to your ear canal and in volume, frequency, and sound memories. Some inexpensive hearing aids are BTE hearing aids that come with a universal ear mold to start you off. They also come with the capability of providing a custom fitted ear mold by taking the aid to your audiologist.

Some inexpensive hearing aids are designed for you to do the programming of the hearing aid yourself with the help of computer software. You have to decide if you are up to that challenge if you choose a package like this.

Some of these inexpensive hearing aids can be fitted through an ENT doctor and some are done without any doctor. Whatever you choose to do about your hearing problems, look for reliable yet inexpensive hearing aids for the solution.

All About BTE Digital Hearing Aids

People who are in the market for hearing aids can get aids that fit in and on different parts of the ear. They can obtain hearing aids that have different kinds of circuitry. BTE digital hearing aids combine a common type of hearing device with the latest circuitry.

For years, there was no such thing as digital processing. Then, when there was, it was too big and bulky to be feasible to be used. Even when it became possible to use, it still wasn't practical until the technology came along to make the circuits tiny like they are today. BTE digital hearing aids are one type of hearing aid that uses this technology.

BTE stands for behind the ear. BTE digital hearing aids have the same basic structure as ordinary BTE aids. They have an ear mold that fits into the ear. This is connected to the hearing aid, which sets behind the ear, by a tube called the tone hook. A microphone sits atop the hearing aid to channel sound into the aid. The BTE aid is durable, powerful, and has easy to use controls.

BTE digital hearing aids are capable of so much more than the analog variety. If you've ever listened to a vinyl record album and then a CD, then you are aware of the difference digital sound can make. However, that's only the beginning of what a BTE digital hearing aid can do.

BTE digital hearing aids function by converting the sound that is gathered by the microphone into bits, computer bits that is. These bits are processed at an amazingly fast rate. They are used in a processor known in the hearing aid industry as a DSP, or digital signal processor.

These DSP's are capable of sorting sounds into channels of frequencies. This is important because certain speech sounds are higher in pitch and other sounds are lower. If you don't have the full range of audible frequencies, speech will sound jumbled to you because you are not hearing all the sounds. BTE digital hearing aids also have more power for amplification to make it even easier to distinguish voices.

BTE digital hearing aids can treat continuous noise differently that they process short duration noises. It only makes sense that, for instance, you would be more interested in the sound of the doorbell than in the sound of the air conditioner running. They also minimize feedback by both their circuitry and by the way the ear mold fits into the ear.

Another problem BTE digital hearing aids correct is recruitment. This is when a person with hearing loss has trouble because soft noises sound too soft and loud noises sound too loud. The digital processing of sound diminishes this problem. Some BTE digital hearing aids offer two microphones to focus on what is in front of the wearer. This is called directionality. It allows for less distraction from the surrounding environment.

BTE digital hearing aids offer the both worlds. They are rugged and easy for even a child to use. They also have the advantages of digital sound processing. For many, it's an easy choice.
