Atmospheric noise

Hey there kiddo, have you ever tried to listen very carefully when it's very quiet at night? You might hear a faint humming or buzzing sound in the background. Well, that's what we call atmospheric noise.

The air around us is constantly moving and changing, and this movement creates tiny electrical currents all around us. These currents can create a bunch of different sounds like crackling, hissing, or static.

It's like when you rub your feet on the carpet and then touch something metal, you hear a little zap sound. That's because your body released some electrical energy. This is kind of like what happens in the air too!

When we tune into radio or TV, we sometimes hear a little bit of static or interference. This is because the signals are traveling through the air, and the atmospheric noise can kind of disrupt them a little bit.

So, atmospheric noise is basically just the sound of all the little electrical currents moving around in the air that can sometimes mess up our electronic signals.
