HEARING AIDS REID COULOMBE

HEARING AIDS  Hearing Aids are used to amplify sound, and improve the hearing of an impaired listener.  It is estimated that 1 in every 10 people in the world suffer from some form of hearing loss.  Hearing loss is caused by damaged cochlea in the ear, or in some cases earwax, fluid in the ear, a genetic problem, or a punctured eardrum.

HISTORY  (1800) First Hearing Aid company was established. Manufactured many types (trumpet ear)  (1947) The transistor is invented, making hearing aids much smaller, and more energy efficient.  (1996) Hearing aids become 100% digital

FUTURE OF HEARING AIDS Improved sound quality Improved settings and user customization Smaller hearing aids Ability to fix damaged ears?
