Sometimes, hearing loss can be congenital (present at birth) or acquired (developed after birth).

The device consists of a microphone, amplifier, and speaker. The microphone picks up sound and converts it into electrical energy. The amplifier makes the sound louder and the speaker sends the amplified sound into the ear. 

Sound waves enter the ear and are amplified by this device. This amplified sound is then sent to the inner ear, where it is converted into electrical signals that are sent to the brain. The brain then interprets these signals as sound.  Hearing aids can be used to improve hearing in people of all ages, but they are most commonly used by older adults and Oro Valley Audiology has the best selection of hearing aids in tucson az
