The most common type of hearing loss is sensorineural hearing loss. Many people who have this kind of hearing loss due to a damage done by disease, aging, or injury from noise or certain medicines.

How does exactly a hearing aid work? It simply magnifies sound vibrations entering the ear. Surviving hair cells detect the larger vibrations and convert them into neural signals that are passed along to the brain.

Just like eye glasses, the more severe a person’s hearing loss is, the greater the hearing aid amplification needed. But be aware that even the greatest amplification can have limits. If your inner ear is too damaged, even large vibrations will not be converted into neural signals. In fact, under this condition, a hearing aid won’t help.

The digital aids works differently by converting sound waves into numerical codes and then amplifying them. This kind of hearing aid provides more flexibility to adjust to the needs and environments. Many people prefer digital hearing aids. But they’re more expensive.

Behind-the-ear hearing aids has a hard plastic case worn behind the ear and connected to a plastic earmold that fits inside the outer ear. The electronic parts are held in the case behind the ear. Sound travels from the hearing aid through the earmold and into the ear. BTE aids are used by people of all ages for mild to profound hearing loss.

In-the-ear (ITE) hearing aids fit completely inside the outer ear and are used for mild to severe hearing loss. The case holding the electronic components is made of hard plastic.

ITE aids usually are not worn by young children because the casings need to be replaced often as the ear grows.

Canal aids fit into the ear canal and are available in two styles. The in-the-canal (ITC) hearing aid is made to fit the size and shape of a person’s ear canal. A completely-in-canal (CIC) hearing aid is nearly hidden in the ear canal. Both types are used for mild to moderately severe hearing loss.

The beauty of a good hearing aid is that it helps people hear more in both quiet and noisy situations. Believe it or not, only about one out of five people who would benefit from a hearing aid actually uses one. Most people either don’t want to wear one, or just simply unaware of its benefits.

A hearing aid has three basic parts: a microphone, amplifier, and speaker. Over the last 2 decades, hearing aids have become better, more powerful, smaller, and cheaper. You can purchase one simple sound amplifier for less than $20. The high end hearing aids can go up to around $200.

It all depends on your personal need and life style. But you should have your hearing checked by a health professional before you purchase any hearing aids.
