A hearing aid is a small electronic device that you wear in or behind your ear. It makes some sounds louder so that a person with hearing loss can listen, communicate, and participate more fully in daily activities. A hearing aid can help people hear more in both quiet and noisy situations. However, only about one out of five people who would benefit from a hearing aid actually uses one.
- hearing aid history
No one person invented the hearing aid. Hearing aids fashioned from horns, sea shells, or other natural material probably existed long before the ear trumpet was first manufactured. Giovanni Battista Porta was most likely the first to actually describe one of these early hearing aids.

Speaking tubes all operate on a common principle - they pick up sound close to its source and direct it via a narrow pathway, usually a flexible tube, to the ear. In operation, the speaker talks directly into a funnel at one end of the tube and the listener holds the small tip at the other end in his ear.
- hearing aid styles
Hearing aids come in various styles, which differ in size and the way they're placed in your ear. Some are small enough to fit inside your ear canal, making them almost invisible. Others fit partially in your ear canal. Generally, the smaller a hearing aid is, the less powerful it is, the shorter its battery life and the more it will cost.
- digital hearing aids
The main difference between analogue, the conventional system, and digital, the new technology, is in their method of conversion. Analogue converts sound waves to electrical waves while digital converts sound waves using exact mathematical calculations that are processed by a computer.

Hearing loss, or hearing impairment (say: im-pare-ment), happens when there is a problem with one or more parts of the ear or ears. Someone who has hearing loss or impairment may be able to hear some sounds or nothing at all. Impairment means something is not working correctly or as well as it should.
