A vibrating object with a large amplitude pushes air molecules with more force, creating a higher pressure wave that our ears interpret as a loud sound. Most musical instruments produce a rich, complex vibration that includes the fundamental frequency along with multiple overtones, or harmonics.
Understanding Sound Wave Compression and Rarefaction
The smoother and more consistent this motion, the cleaner the resulting sound wave will be. A high frequency, where the object vibrates extremely fast, results in a high-pitched sound, such as a whistle.
As an object vibrates forward, it compresses the air molecules in front of it, creating a region of high pressure known as a compression. How Vibrations Create Waves Imagine dropping a stone into a still pond.

Vibration Speed Frequency Range Perceived Sound Fast High (e. Resonance plays a crucial role here, as certain frequencies are amplified by the shape of the instrument or the room, giving a guitar its distinct sound versus a piano playing the same note.
