The type of hearing aids that we have today have been around for literally decades. In years past the first type of hearing device required the person to hold a conical shaped device to their ear. Though not very convenient, these early cone-shaped devices worked by focusing and exaggerating the sound through the funnel into the ear.
Anyone can tell you that our current hearing devices take advantage of much greater technology, but many do not realize just how that technology works.
How Hearing Aids Work?
The way that hearing aids work is by increasing the small sounds outside the ear with the help of tiny microphones inside the aids. As that sound is received by the device, it is converted to an electrical or digital signal, that data is then sent back to a speaker where it is turned into sound again.
Depending upon the environment around them, and the exact environment the person is in, the settings for different microphones will vary. Environment is measured by the noise level and quality around a person. The needs of the person who maintains a quiet conversation environment will be drastically different than that of a person who is constantly exposed to high pitches and frequencies. These different factors will help your audiologist adjust the settings on your device but this is only part of the answer as to how they work.
3 Types of Hearing Aids
For hearing aids, there are three essential types of hearing aids that help to receive and convert the signals. The least advanced is the analog adjustable and it costs less than the other two types. Comfort, volume, and any other specifications can easily be adjusted by the wearer's audiologist with this type of technology. The piece will be constructed in a factory based on custom designs, and the volume control will be adjusted either manually or automatically.
Analog Programmable Hearing Aids
Through the analog programmable is another way the hearing aid works. The analog adjustable is considerably behind this version of circuitry because the analog programmable can be programmed by a computer. The audiologist does the initial programming, selecting a variety of sound capture and transmission types that would appropriate in different situations.
Since different situations require different settings, the user is furnished with a remote control to control the settings. The device that is the most expensive and most advanced is the digital programmable device. It took a good deal of time to get this device to be an alternative people could use, as it was first impossible to make, and then too large to be of any use so scientists have since refined the process.
Digital Sound Processing Hearing Aids
DSP, or Digital Sound Processing, is a circuitry found in hearing aids. Analyzing the sound before it reaches the ear through the use of computer chips is how these work. Through the use of billions of digital number codes stored in the device, the sound is given the correct setting. Before the data gets sent through the ear, it has to be changed back into sound.
The digital models also have the capability of detecting and eliminating feedback by identifying the frequencies which work automatically with little adjustment from the wearer.
Advancements in Technology Make Better Hearing Aids
In recent years, hearing aids have increased dramatically. People who want to hear better have many options now. For anyone who might wonder how hearing aids work, the answer lies in advancements in technology.

The Best Hearing Aids For Your Money
By Matt Murren
As if suffering from hearing loss wasn’t frustrating enough, now you have to sift through endless choices to determine the best hearing aids. There are literally thousands of hearing aids available, each claiming to be the best hearing aids available. Not to worry, though. We’ll give you the low-down on what’s what in the world of hearing aids. It all basically boils down to three different styles of hearing aids:
Behind the Ear Models
This is one of the best models for children with hearing problems. They are the most powerful, have the longest battery life, and are less difficult to adjust the volume. They are typically larger than other styles; the exception to this is the open fit model. The open fit model is better suited to people with hearing loss affecting only their ability to hear high frequencies. With both behind the ear types, the base goes behind the person’s ear. Sound travels through a tube and inside a mold specifically designed for the wearer’s ear canal.
In the Ear Models
For people who don’t mind the hearing aid going in their ear, but don’t want it going into the canal, here are the best hearing aids for you. In the ear models are relatively large (like behind the ear models). Its size lets manufacturers add on accessories like directional microphones or a telephone switch. These models are easy to put in and take out.
In the Canal Models
In the canal hearing aids, as the name implies, go into the ear canal itself. Some of them, called completely in the canal, go all the way in, while regular in the canal hearing aids only go part of the way in. Both are small and are designed to be discrete. They are custom fit by an audiologist. While they are more expensive, and while it is harder to change the battery or adjust the volume, they provide a nice option to those who don’t want others to readily notice their hearing problem.
The Bottom Line...What’s the Best Hearing Aid?
Which of these is best? It depends on what your primary goal is. If you’re looking for a cost-effective, easy to operate hearing aid, you’ll likely prefer either the in the ear or behind the ear style. If you’re more interested in a more expensive, but more transparent and less cumbersome hearing aid, you’ll be turned on by the sleek design of in the canal models. Before buying any hearing aid, be sure to visit an audiologist, who can recommend a model that best suits your lifestyle. They can also offer alternatives, such as cochlear implants and bone conduction implants.

How to Buy a Hearing Aid
By Marlo Sollitto
Behind-the-ear hearing aids, in-the-ear hearing aids, completely in the canal hearing aids, binaural hearing aids...and the list goes on. With so many types and hundreds of brands to choose from, what is a senior to do? First and foremost, don't go it alone. Too often, seniors are wooed by a catchy ad or a pushy salesman and wind up with an expensive hearing aid that they shove in a drawer and never use. Work with a qualified audiologist who can conduct a thorough hearing evaluation, determine the type and degree of hearing loss and recommend the appropriate hearing aid, says Dr. Phillip L. Wilson, Au.D., Head of Audiology at Callier Center for Communication Disorders, University of Texas at Dallas.
The first thing the audiologist will do is to perform some basic hearing tests, including:
Pure tone air conduction audiometry. Patients listen to a range of beeps and whistles (called pure tones) and indicate when they can hear them, by pressing a button or raising their hand. The softest sounds they can hear (hearing thresholds) are then marked on a graph called an audiogram.
Pure tone bone conduction audiometry. This test helps determine where in the ear the hearing problem lies. If in the middle ear, the hearing loss can usually be treated medically. But inner ear hearing loss means the sensory cells are not working properly, and that problem is permanent.
Speech audiometry. Patients are asked to repeat words and sentences in quiet and in noise to help the audiologist understand the practical affect of the hearing loss.
Tympanogram. A test of how well the middle ear system is functioning and how well the eardrum can move.
After conducting the tests and isolating the hearing problem, if a hearing aid is the right solution, Wilson says an audiologist should perform a lifestyle needs analysis to determine the type of hearing aid that will work best for your loved one. Some questions the doctor should ask your loved one:
How active are you? Do you have trouble communicating in noisy places? Do you live alone? In an apartment? In a large home? Do you talk on the telephone a lot? Watch TV often? Do you regularly go out to eat at restaurants? Do you have trouble hearing certain family members such as women or children? Do you have trouble hearing at religious services, at lectures and at movies?
Features to look for
Hearing aid technology is constantly improving, and new products are being introduced all the time. To understand what your loved one needs, you first must know how a hearing aid works.
A hearing aid has three basic parts: a microphone, amplifier, and speaker. The hearing aid receives sound through a microphone, which converts the sound waves to electrical signals and sends them to an amplifier. The amplifier increases the power of the signals and then sends them to the ear through a speaker. The hearing aid can be programmed on a computer to customize the amplification specifically for your hearing loss.
According to Dr. Wilson, here are some of the newest advances in hearing aid technology that you can discuss with your audiologist:
Open fit aids. A common complaint among people with hearing aids that fit into their ear is that they hear distractions, such as an echo when they speak; or hearing themselves chew. A new class of hearing aids addresses this issue. Called "open fit"aids, these hearing aids sit behind the ear, with only a wire and tiny loudspeaker going into the ear.
Digital feedback reduction. New hearing aids have good feedback reduction, to reduce or eliminate another common hearing aid complaint: whistling noises.
Digital noise reduction. Using complex algorithms, this feature is making hearing aids "smarter" and able to tell the difference between speech and background noise.
Directional microphones. The directional microphone allows the user to focus on whoever is directly in front with reduced interference from conversations behind and to the sides.
Automatically adaptive. With this technology, the hearing aid changes the way it works when the user walks from one place to another. The hearing aid detects sounds exceeding a certain loudness level, and then self-adjusts to reduce the amplification. For example, in a quiet place, volume level will increase. In a noisy environment, directional mics will kick in as well as noise reduction features.
Bluetooth compatible. The user doesn't have to hold the cell phone up to their ear, which alleviates the feedback some people hear when they answer the phone. When a call comes in, it rings through the hearing aid itself, instead of ringing from the phone. To answer, the wearer simply presses a button.
Even after selecting the right hearing aid, don't expect your loved one to adapt immediately. Wilson says it often takes a month or more for patients to get used to their new device.
"Often, people who are using a hearing aid for the first time will be startled at how loud the world is," he says. "Sounds may seem loud and disturbing. Suddenly, the refrigerator makes a roar, the newspaper rattles, even the turn signal in the car becomes disruptive. I recommend that people wear the hearing aid all day, every day. If you wear it only sporadically, you will never get used to the volume of new sounds, and the brain will be confused. It takes at least several weeks for the brain to put those new sounds into perspective."
So be patient. It requires time to adjust to hearing aids. Your loved one's listening skills should improve gradually as he or she becomes accustomed to amplification.
The FDA requires that manufacturers provide a 30 day trial period for all hearing aids, so take advantage of it. Ensure your loved one uses the hearing aid for more than a few days, especially since there's no risk involved. It can be returned for up to 30 days. Being an effective "matchmaker" does take time. But it's time well spent.
