There are various experiments related to Oscillation— the very basic property of sound wave.Oscillation means moving back and forth.Normally the oscillating wave has three key attributies,they are:
1,Frequency / Rate,repetition for time units
2,Amplitutde
3, Phase / be shifted from one direction to another
A bunch of audio-visual experiements can be found that focus on the variation of oscillation frequencies for motion elements:
John Whitney’s Music Box is probably the most famous one: http://whitneymusicbox.org/
Memo Akten’s ” Simple Harmonic Motion study” series are fundamental animations with oscillating dots by coding:

There also physical installations can be found to present the concept of oscillation,for example:
