Close your eyes for a moment and listen. Maybe you hear people talking, music playing, or even your own breathing. But what is sound, really? How does it travel from one place to another? And why do some sounds seem high-pitched while others are deep and low?
In this chapter, we will explore the science of sound! You’ll learn how sound is created, how it moves through different materials, and why we hear things the way we do. We’ll also dive into vibrations, frequencies, and decibels, and even discover how sound can be used in technology—like ultrasounds and noise-canceling headphones!
