Squelch

Squelch is like a button that you press to stop annoying sounds on the radio. Imagine you are listening to a walkie-talkie and there is a lot of static noise that you cannot understand the other person speaking to you. When you turn on the squelch, it deletes the noise and makes your conversations crisp and clear to understand. It's like a filter that removes anything that isn't necessary to hear. Squelch is important for communication devices like radios because it helps you get rid of unwanted noise and interference so you can hear the information you need.
