Personal sound amplifier structure

Personal sound amplifiers are usually small, simple devices. They amplify the sound and pass the result to the user's ear. The main components are microphones, amplifiers, speakers, volume controls and power supplies.

The microphone captures the sound (pressure) wave and converts it into an electrical signal. An amplifier (electronic circuit) uses a power source (battery) to increase the amplitude of the electrical signal. The speaker converts the amplified electrical signal back into sound waves. The volume (gain) control is used to adjust the amount of amplification applied to the electrical signal to indirectly control the volume.

These devices come in size from a small box (with headphones) worn around the neck or suspended from the belt - a small package that fits inside the ear canal. These smaller devices look like hearing aids, but are simpler and cannot correct hearing loss.
