When the rubber bands are plucked in order, from thinnest to thickest, the sound will gradually change from a high pitch to a low pitch. When a ruler "bridge" is added, it absorbs some of the vibrations. ... The shorter length of rubber band makes a high, short sound and vibrates at a faster rate or frequency.

What sound does a rubber band make?
If you pluck a rubber band, the rubber band moving back and forth produces twanging sounds. Unless something vibrates , there can be no sound. Sound travels when a string vibrates, it makes molecules of gases in the air next to it vibrate. The molecules squeeze together, then spread apart.
What happens to the sound when you stretch a rubber band?
The more you stretch the band, the more tension it is under and the faster it vibrates up and down. The number of vibrations every second is called the frequency and this tells you exactly how high or low the note is.
What factors affect the pitch of the sound produced by rubber bands?
Different rubber bands will produce different resonant frequencies, depending on their thickness or width, and how tightly they are stretched. Thicker, heavier, and loosely stretched rubber bands will sound lower pitched, while thinner, lighter, tightly stretched rubber bands will sound higher.
