A hearing aid is a small electronic device designed to amplify sound for individuals with hearing difficulties or hearing loss, helping improve listening and communication. Its components include:
• Volume Control Potentiometer – adjusts the loudness
• Microphone – captures external sounds
• Amplifier – increases the strength of the sound signals
• Fine-Tuning Potentiometer – allows precise sound adjustment
• Shell – the outer casing that houses and protects all components
• Receiver – delivers the amplified sound into the ear
These components work together by capturing external sounds, processing and adjusting them according to preset programs, and finally transmitting the enhanced sound to the eardrum at a louder and clearer level, enabling individuals with hearing loss to hear more effectively.
