Sound energy is all about vibrations! When something vibrates, it creates sound waves that travel through the air (or water or even solids!) to our ears. Our ears then translate these vibrations into the sounds we hear. Different vibrations create different sounds – loud or soft, high-pitched or low-pitched. Understanding sound energy helps us understand how musical instruments work, how animals communicate, and even how doctors use ultrasound!
