What is Sound?
Sounds are everywhere! Did you know sound is a type of energy? Anything that makes sound is using energy. If it's not using energy, it's not making sound. The loudness of a sound depends on the amount of energy used to create it.
Think about closing a door. A door that is closed gently will use less energy, while a door that is slammed will use more energy.
Which do you think would sound louder? A door that is slammed, of course! More energy is used to slam the door shut, which will result in a louder sound created.
