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.

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 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.
