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!

They do, but usually only in specific spots for specific frequencies since the waves are not only all different frequencies and phases, but emanating from different physical locations.
Reflective surfaces where the same sound source can pass through the same spot twice generally work best to demonstrate it. However, it sounds more like adjusting an EQ on a stereo than the source actually disappearing.
