In this article, we will learn the basic mechanism of the working of a simple hearing aid apparatus. These days, we see invisible hearing aid apparatuses which are quite small in size and are almost invisible when looked from a distanced. Following are the main components of a good hearing aid equipment,

• The microphone
• The amplifier, and
• The receiver

These things work exactly as their name suggest. Microphone would receive the sound signals and amplifier will enhance these signals and send the same to the receiver. At that point, a small speaker is attached which produces the enhanced sound and helps the patient to listen the surrounding sounds in a better way. Modern hearing aids reduces the extra sounds and help the person to hear to only those sounds which are more meaningful. These sound frequencies can be changed from the settings too.
