Hearing aids are apparatus worn in or behind the ear. They are available for those with varying levels of hearing loss, and help to make sounds more clear. They can vary in size and shape, with two main types:

Analogue hearing aids are the cheaper of the two, and are able to increase all sounds. However, this can be a drawback as it can increase background sounds you do not wish to hear.

Digital hearing aids are highly thought of but more expensive. They are able to boost the sounds of speech, while reducing other unwanted sounds. The sound quality is similar to that of a CD, and with the use of a computer doctors are able to programme hearing aids to individual patient condition.
