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!

On theory they do, just very very uncommon.
Imagine a dart board where if you throw two darts at the same time, on opposite sides of the board, the same distance from he Bulls eye both darts disappear. But only if it they hit at the same time, location and distance (can even add in strength).
By just Throwing randomly at change this would never happen, but it it would be trivially easy to prepare the darts a cm apart and push them in at the same time. In the same way with sound the chance that everything randomly aligns is basically non-existing, while with a dedicated setup we can create the system quite easily.
There is one famous middel ground. Music halls. Many music contains very narrow frequency and stable notes which can lead to places in the hall where the music is more or less loud.
