The three basic components of a hearing aid are microphone, amplifier and the receiver. The microphone serves as the reception device that captures sound waves. The microphone is responsible for taking auditory sounds (sounds that humans can hear) and converting them into electronic sounds that are detected by the amplifier. The amplifier takes the sounds transmitted from the microphone and makes them louder. Hearing aids are often designed for specific hearing needs; this is because amplifiers can "choose" which sounds to augment. In modern hearing aids, precision amplifiers often eliminate background noise. The receiver simply serves as a speaker function and converts sound waves from auditory to electronic.
