There are two primary categories: A conductive loss happens when abnormal conditions, such as immobilization of the tiny ear bones, result in reduced sound sensitivity in the outer and/or middle ear. A sensorineural loss occurs when there's reduced sound sensitivity to the brain caused by abnormal conditions affecting the inner ear or nerve pathways. When both types occur together, it's referred to as a mixed loss.

Conductive losses can result from earwax buildup in the ear canal, perforated eardrum membranes, or ear infections. Sensorineural losses may be caused by continuous exposure to loud sounds, the natural aging process (known as presbycusis), viral infections, head trauma, birth defects or hereditary conditions, and even certain medications.

The vast majority of hearing aid users today have a sensorineural or nerve-type loss.

Several indicators are readily apparent, including increasing TV volume, trouble understanding speech when background noise is present, believing others mumble or speak too quietly, relying on lip reading, positioning oneself in specific locations in public settings to hear better, and experiencing ringing sounds in the ears (known as tinnitus).

It involves straightforward procedures designed to assess a person's hearing and comprehension abilities. The evaluation includes presenting various tones through an electronic device called an audiometer to determine which sounds can be heard and how well. It also involves special word groups that the patient repeats, allowing the hearing specialist to identify the volume levels at which words are first heard and how clearly they're understood. The complete evaluation results help determine if hearing aids would be beneficial.

Hearing aids won't restore normal hearing, and they can't prevent or reverse a hearing impairment caused by an organic condition. That said, they continue to provide a beneficial experience through improved hearing for millions of people with hearing loss.

There are five primary styles: in-the-ear and in-the-canal devices fit completely within the ear's contours. Additional ear-level options include behind-the-ear and eyeglass models. A larger style is worn on the body or clipped to clothing. Body-worn aids are primarily used by children or individuals with the most severe aidable hearing losses.

Sometimes called an earpiece, this device fits into the outer ear and transmits sound waves from a hearing aid receiver into the ear. An earmold is created by taking an impression of the ear using a soft plastic material, from which a permanent plastic mold is then fabricated.

A single hearing aid provides the advantage of improved hearing in one ear. However, since individuals with normal hearing achieve optimal listening through both ears, it stands to reason that those with hearing loss would benefit most from using both ears. Many binaural or two-ear users report that dual hearing aids offer better hearing with less amplification, balanced hearing from both sides, improved sound localization, and more natural sound quality.

Similar to automobiles, hearing aids are available in various models and styles. Basic devices are designed mainly to provide appropriate amplification. More advanced options feature adjustable tone and power controls, automatic sound processing circuitry, telephone switches, and other specialized functions. They accommodate hearing losses ranging from mild to the most severe aidable impairments. With different models and features available, hearing aid prices vary. To find the best device for your specific needs at a fair price, we recommend consulting with an ethical, reputable specialist.
