What are the possibilities of creating small sonic boom(s) from commercial or consumer grade motors/centrifuges/fans bolted to the floor? If possible, is there anything available to the scientific community for such?
You can take a syringe, stick some plastic wrap between the needle and the syringe body and then push in the plunger, thereby making a miniature shock tube. As soon as you squeeze hard enough to pop the plastic wrap, that pop sound is the result of creating a shock wave and could be described as a sonic boom. It's just a little pop, though.
That goes back to Baluncore's question: Why do you want to generate a sonic boom?
