Modern day hearing aids are mostly electronic in order to produce a better-quality amplification of the sound energy and is also a much more comfortable alternative compared to its predecessors.

Hearing impairment is caused when the nerves which stimulate the brain to process sounds, loses its cells and is unable to effectively transmit and interpret sound. There are minute hair-like receptors in the ear canal which process sound and interpret their various frequencies. In case of a hearing impairment, these receptors are damaged which renders a person unable to distinguish between the sounds.

There are a few factors which affect the overall hearing of a person, even with hearing aids.

Occlusion occurs when the person wearing a hearing aid, tends to hear booming and hollow echo sounds of their own voice. A very common example is when normal people chew, the sound escapes through the ear canal.

The compression effect occurs in case a person who is using a hearing aid subjects himself or herself to loud sounds. Since the purpose of a hearing aid is to amplify sounds which are normally not audible, this doesn’t necessarily help when sounds which are loud enough are amplified beyond need.

There are a number of ways to evaluate the hearing aid outcome, which will ultimately assist in you figuring out the best possible hearing aid for your needs.
