Noise Pollution
Noise Pollution is unwanted loud sound that can harm hearing and make it hard to focus.
Think of it this way
When someone runs a blender near you in the kitchen, the loud sound fills the room and drowns out other sounds. You can't hear someone speak to you, and it's hard to think. That's noise pollution. Too much sound in a space can hurt your ears and block your ability to focus.
