ok so I know that sound (like sounds playing off a speaker) is a thing that has been banned from being suggested but what about "sound" from air in a simulation. so this got me thinking, and an idea formed

USND: Ultra-sonic device, produces high-speed airwaves that can break certain materials, PSCN to activate, and NSCN to deactivate

properties:

• as stated before, USND produces waves of fast-moving air pressure, the frequency of these waves are based on USND's life and the power of the waves themselves are based on the temp.
• electronic can be destroyed by EMP when on

that's it really, may add more if i think of something
