The pure periodic sound is the simplest sound event. It corresponds to a regular sine vibration (= harmonic vibration) of pure frequency. The sound of a tuning fork is the nearest of all non-synthetic sound sources to this ideal.

Information and ideas:
Suitable for demonstration purposes but also good for self-study on the part of the students. Idea: show the video without sound to begin with. The students should then guess what sort of noise/sound it might be.

Relevant for teaching:
Acoustic phenomena
Sound/acoustics: parameters
Communication and understanding
Vibrations and waves
