I get constructive and deconstructive, but those are usually in the context of being the same frequency and just being out of phase. I’m talking like…you and your bud having a conversation in a restaurant, with music playing, convos around you, sound of wait staff, etc. If a waiter drops a plate, how does that sound transit through at that higher, unique frequency through all the other noise so that all can hear it?
Thank you for your time!

Look up noise cancelling. Only an ‘equal but opposite’ sound, in an oscilloscope/wave sense, can cancel/’erase’ another specific sound wave. That doesn’t happen by accident.
