When you stretch the rubber band it creates tension that is transferred into kinetic energy when you release it and so it moves and in moving it moves in turn the air around it and the air vibrates your ear drum creating a noise (it is a higher pitch if it is tighter because the rubber band is more tense so it moves the air faster thus the higher sound)
The sound a rubber band makes when released is a 'twang'.

One can produce a soft, high-pitched sound from a stretched rubber band by snapping it. It is easier to accomplish this if the band is stretched very tightly.
The stretched membrane on the timpani vibrates when it is struck which makes sound.
Some possible options for sound insulation between walls are the use of the following sound proof materials; sound insulation wall layer, curtain walling, the soni protector sound proofing panels, foam and sound proof rubber.
is there a difference in the sound produced by each of the rubber bands?how do they refer?
The oscillation of the rubber as it vibrates - forces the air around it to vibrate also. This is the sound we hear.

Your answer will be "Chordophone".
its air leaving the space between your fingers that's why there's a "popping" sound when done.^_^
Chordophone
A stretched-out area of a wave is called a rarefaction.
When you hear a high sound the vibrations are moving very fast. When you hear a low should, the vibrations are moving slowly. You can test this experiment if you use a bowl and some rubber bands. Strap some of the rubber bands around the bowl in different places. when the rubber band is stretched longest (in the middle of the bowl) it is tighter when you strum it than in other places. This means the frequency is higher than in lower places. Band stretched tight = Faster vibrations = Higher sound Band stretched loosely = Slower vibrations = Lower sound

A musical instrument which produces sound by vibrating strings stretched between two fixed points is a chordophoneinstrument.
What is a tightly stretched membrane that vibrates when sound hits it
The stretched membrane on the timpani vibrates when it is struck which makes sound.
That would be a stringed instrument.
Think of it as a rubber band. No vibration, no sound. it's the same with a rubber band!
