Sound waves require a matter medium (solid, liquid, or gas) to travel through, and cannot travel through vacuum. The amplitude of a sound wave corresponds to its loudness. The frequency of a sound wave corresponds to its pitch. The speed of a sound wave depends on the medium its traveling through. Sound waves exhibit wave behaviors like reflection, which are useful in a variety of applications.

But how does the air start vibrating? Explore the intriguing science of sound waves and how they travel. Learn how speakers use oscillation to create sound, and discover why sound waves can transport energy without moving the medium itself. Uncover the mystery behind the difference in our voices in person and on recordings.
