There are several different types of hearing impairments. Some are caused by old age, while others are hereditary or caused at birth. Whatever the cause of the hearing impairment, living with this disability is a life altering challenge.

Introduction

There are a few basic types of hearing loss. One is conductive hearing loss. This happens when there is a problem with the outer or middle ear. Most people with conductive hearing loss have mild and temporary loss, which can be medically treated. The cause of conductive hearing loss usually occurs at birth in the form of malformed parts of the ear. At times there may be tiny holes in the eardrum, or wax builds up in the ear canal. Acoustic Neurinoma is an example of this type of hearing loss. It is a benign tumor, which forms on the nerves in the inner ear. This tumor causes the vibrations from the inner ear not to be transmitted to the brain therefore prevents the person from hearing sounds. Another type of hearing loss is sensory hearing loss. The cause of this type of hearing loss can be hereditary, or can be caused in the fête, if a pregnant mother suffers from certain types of diseases. Sensory hearing loss can also be caused by severe damage to the head or by listening to or being around loud noises such as music or fireworks on a constant basis. This type of hearing loss occurs when the cochlea is not working properly. The hairs inside the cochlea have been damaged in sensory hearing loss. Often times the damage is permanent. The loss of hearing can affect one ear or both, and it will often affect the speech of a person. Mandeni Syndrome is also related to the cochlea, however in this case the cochlea is not complete or abnormally shaped. Mixed hearing loss is a combination of conductive and sensory hearing loss. Neural hearing loss occurs when there is a problem with the connection from the cochlea to the brain. One condition of neural hearing loss is auditory neuropathy, in which the cochlea of the ear functions properly; however, the nerve receptors to the brain do not. As stated before, there are also severe diseases that can cause hearing loss. Perhaps the most deadly and dangerous of these diseases is Meningitis. Meningitis is a severe sickness with symptoms such as high fever and extreme fatigue. Often people suffering from Meningitis will gradually experience hearing loss, as was in the case of Helen Keller.

How a Hearing aids work?

For the estimated 28 million Americans with hearing loss, life is a series of missed opportunities. Frustrated friends and family members often tire of shouting and will just give up on communicating altogether. This can make the world a very lonely place for the hearing-impaired. Hearing aids -- small electronic devices that amplify sound -- can help restore many of the sounds that hearing-impaired people are missing. However, research finds that very few people who need hearing aids actually use them. Only one out of every five Americans who could benefit from a hearing aid wears one, according to a 2006 study from Duke University.

Some people pass on hearing aids because of the cost, while others do so because they are embarrassed to be seen wearing them. What they don't realize is that many hearing aids are relatively inexpensive, and many of today's hearing aid styles are so small that they are nearly impossible to spot.

In this article, we'll find out exactly how hearing aids work, and learn about new technologies that are providing clearer, more natural sound for people with hearing loss. But first, let's look at what causes hearing loss.

What Causes Hearing Loss?

When you listen to something, whether it is a car alarm or a dog barking, the sound travels through the opening of your outer ear and causes your eardrum to vibrate. Three small bones in your middle ear carry this vibration to the cochlea -- the shell-shaped structure in your inner ear. The vibration stimulates hair cells, which create an electrical current in the auditory nerve. This current transmits the sound via nerve impulses to your brain, where it is processed into noise, like the sound of a car alarm or that of a dog barking.

People lose hearing in one of two ways:

Conductive hearing loss occurs when sound doesn't move as it should through the eardrum, ear canal or the three bones of the inner ear. It can be caused by earwax, a punctured eardrum, fluid in the ear, a genetic defect or an infection. The result is a sensation as though your ears are plugged. Conductive hearing loss can be treated with surgery.

Sensor neural hearing loss involves damage to the cochlea. It's the most common type, affecting about 90 percent of people with hearing loss. Sensorineural hearing loss can be a byproduct of aging, or it can occur due to infections, genes, head trauma, exposure to loud noises or fluid buildup in the inner ear. This is the type of hearing loss that a hearing aid can help.

Hearing aids aren't effective for everyone. Hair cells in the inner ear must pick up the vibrations that the hearing aid sends and convert those vibrations into nerve signals. So, you need to have at least some hair cells in the inner ear for it to work. And, even if some hair cells remain, a hearing aid won't completely restore normal hearing.

Types of Hearing Aids

 

People with hearing loss have several hearing aid styles from which to choose. Generally, the smaller the hearing aid, the more it costs and the shorter its battery life.

In the ear (ITE): This large hearing aid works well for people with mild to severe hearing loss. It fits completely in the bowl of the ear. Because it is so large, the ITE hearing aid is among the most visible of styles, but the batterylasts longer than in smaller aids, and it can accommodate directional microphones (more on that later) and other added features.

In the canal (ITC): The ITC hearing aid works only for mild to moderate hearing loss. It is customized to fit the size and shape of the person's ear canal. Although this hearing aid is inconspicuous, its small size makes it difficult to adjust and change the battery. Some ITC hearing aids come with a remote control to make changing the settings easier. Also, users sometimes experience feedback noise with this type of hearing aid because the microphone and receiver sit close together.

Completely in the canal (CIC): This hearing aid is also appropriate for mild to moderate hearing loss, and it's even smaller than the ITC hearing aid. In fact, it's so small that a user must pull on a small wire to remove it from his ear. Because it fits completely in the ear canal, the CIC hearing aid is barely visible. Again, though, its small size makes it difficult to adjust and use added features. It's also more expensive than larger hearing aids.

Behind the ear (BTE): The BTE hearing aid can help with all types of hearing loss, from mild to profound. The electronics are in a case that sits just behind the ear. The case connects by a piece of clear tubing to a plastic piece called an ear mold, which sits inside the ear. Sound travels from the ear mold into the ear. This powerful and adjustable hearing aid can accommodate progressive hearing loss, as well as growth, which makes it ideal for children. However, its size and the tubing attaching the electronics to the ear mold make it very visible. Also, the BTE hearing aid can cause feedback if it's not fitted correctly.

Behind the ear open fit: This newer version of the BTE model solves the problem of visibility. It is so small that it can barely be seen. A tiny device sits behind the ear and is attached by a tube to a miniscule speaker inside the ear canal. This hearing aid doesn't require an impression for fitting, and it provides better sound quality than ITE hearing aids. The downside is that it works only on people with mild hearing loss who can still hear low- and mid-frequency sounds information. It sends this digital information to the implanted receiver, which changes the digital information into electrical signals and sends these signals to the electrode array. The electrode array sends these signals to the auditory nerve, which then passes along the signals to the brain.

Hearing Aid Accessories

The most basic and essential component of any hearing aid is the battery. Without it, the hearing aid won't work. Most hearing aids use zinc-air cells, which are powered by oxygen, but a few use mercury batteries. The size of the hearing aid dictates how long a battery will last. Larger hearing aids have bigger batteries, which can last for about two weeks. Smaller batteries work for three to five days, on average.

Buying a Hearing Aid

If you think you need a hearing aid, the best place to start is with a visit to an ear, nose and throat (ENT) specialist and/or an audiologist. The ENT will examine you to make sure there's no underlying problem causing your hearing loss, such as an infection or buildup of earwax. Then the audiologist will assess your hearing in a soundproof booth to see how well you can pick up sounds at different frequencies. The audiologist will also fit you for your hearing aids by making an impression of your ears. After the hearing aids have been made, you'll return to the audiologist for a fitting and to have the hearing aid programmed. You'll learn how to clean your hearing aids, adjust the volume and change the batteries.
