# sound
Sound is a pressure wave, and this tag is where the site turns that abstract statement into something you can actually hear and see happening. Wave Interference shows two sound sources reinforcing and cancelling each other, Beat Frequency demonstrates the throbbing pulse that appears when two close pitches overlap, and Acoustic Impedance covers what happens when sound crosses between different media. On the musical side, Acoustic Guitar Physics and String Physics — Vibrating String & Harmonics model how a plucked string generates a tone, Musical Scales explores the mathematics behind pitch and intervals, and Standing Waves in Pipes and Room Acoustics extend the same ideas to wind instruments and physical spaces. Echolocation rounds things out by simulating how bats and sonar use reflected sound to "see."

What's the throbbing "wah-wah" effect simulation?
Beat Frequency — it shows the slow pulsing that results when two sound waves of slightly different frequency overlap.
Is there anything about how animals use sound?
Echolocation simulates how bats and sonar systems locate objects using reflected sound waves.
Which sim covers musical instruments directly?
Acoustic Guitar Physics models a plucked string's tone, and Musical Scales covers the frequency ratios behind pitch and intervals.
