This video is a foundational lesson that explains—through easy-to-follow experiments and animations—how the sounds we hear every day are created, travel through the air, and are ultimately perceived by the human ear. Although it was originally designed for teens (ages 13–19), it systematically covers core knowledge that is valuable for anyone who works with sound.
- Three principles of sound generation — striking, rubbing, plucking
- Properties of sound waves — frequency = pitch / amplitude = loudness
- Anatomy of the ear and the pathway of sound
- Decibels & noise-induced hearing loss — how high volumes affect hearing and how to protect yourself
- Evolution of audio technology — microphones, loudspeakers, and Yamaha’s contributions
