Technology has greatly impacted the lives of modern humans. These days, there seems to be no action that we can do without needing the aid of some machine or other. The advancements in technology have immensely benefited the entire human race by improving the quality of our lives in almost every area of existence.

Hearing aids are relatively simple devices composed of four basic parts.

Hearing-Aids

It has a microphone which picks up sound and converts it into an electrical signal which it then sends to the amplifier. The amplifier increases the volume of the sound then transmits it to the receiver. The receiver or speaker converts the electrical signal back into sound and sends it to the ear. A hearing aid also has a battery which makes it work. Continue reading
