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!

Sound is best described in terms of ripples on a surface of water. If you have two perfectly counteracted sounds you can cancel them out, but one loud noise and another softer one don’t necessarily counter each other out, they only add to the entropy (background noise of energy) of the system. I’m always reminded of my aunt and uncles lake house, when I would wake in the morning, the lake was always glassy and still. However by noon time, the power boats would be out, and stirring up the water, the surface never really calming down despite there not being a boat in the vicinity. Sound works the same way, sound just adds to the entropy of the system increasing the heights of the waves as they bounce around, rarely canceling each other out. That’s why New York is noisy, lots of people, and energy, and noise all melding and mixing togeather.
