There are millions of people in the United States that have some sort of hearing impairement or hearing loss. Whether this hearing loss is due to environmental factors, genetics, or some type of disease or physical injury, hearing loss can be difficult to handle. Dealing with the effects of hearing loss is a much easier process with hearing devices that amplifies sounds. Amplification of sound is possible with the use of a hearing aid. A hearing aid is an electroacoustic apparatus that goes in or behind the ear and amplifies and modulates sound.
There are several types of hearing aids, such as body worn hearing aids; behind the ear aids; in the ear aids; receiver in the ear aids; in the canal, mini canal; completely in the canal; bone anchored hearing aids and eyeglass aids. There are other types of hearing aid technology that help to assist those who have hearing loss. There are often complaints about wearing hearing aids such as problems with the initial fit of the device, or the occlusion effect, which is when an object fills the outer ear canal and a hollow or echoing of their own voice occurs.
Hearing aids don’t correct hearing loss it simply aids to make sounds more accessible. There are times when hearing aids are not very effective. Ineffectiveness of hearing aids can occur when regular stimulation does not occur in the primary auditory cortex and can also occur when hair cells in the inner ear are damaged resulting in sensorineural hearing loss.
