A remarkable variety of sounds can be made by striking objects a single time with a stick. The familiar sound of a snare drum, a steel drum, or even the laser chirps in the video above are all made by delivering a quick impulse to the respective systems. How can it be that a single impulse can give rise to all of these sounds, each of which is composed of a unique, rich blend of frequencies?
Details
- A very fast strike to a system (like a drumstick quickly hitting a drum) is called an impulse.
