Above is what I can do with deepsite by pasting in the first page of your lemmy profile and the prompt:
"This is double_quack, a lemmy user on Lemmy, a new social media platform. Create a cool profile page in a style that they'll like based on the front page of their lemmy account (pasted in a ctrl + a, ctrl + c, ctrl + v of your profile)."
It not perfect by any stretch of the imagination, but like, its not a bad starting point.
Doing so outside of a controlled laboratory setting would be effectively impossible for real world noises.
Actually it happens all the time, because of reflection/ refraction from a single source. Say you've got a table saw running in a shop. The sound coming from the saw is a (fairly) constant oscillator.
A shop has hard surfaces and that sound will bounce all over the shop the saw is in. Because it still takes time for the sound to travel and bounce all over, there will be places where standing waves of constructive or destructive interference form. Now there is also a shit ton of other sound bouncing all over the place, so it might not be as noticeable, but standing waves/ regions of constructive/ destructive interference don't require a lab setting.
Modern phased array antenna are effectively taking advantage of this phenomena.
So lets talk about constructive versus destructive interference.
First off, waves are waves. When you have something like a fan, its generating a series of waves. These waves are typically coming at a constant frequency. The frequency here matters.
Sound travels in waves. These waves are pressure waves in a fluid. Those waves don't just get absorbed by hard surfaces; they reflect or refract. But those waves are both moving through the space, and themselves have a frequency.
This is important because of this you get patterns of constructive and destructive interference in space.
In some areas of a space there will be amplification, because the frequencies are lining up. In some spaces, the waves will cancel out. Those areas will be quieter.
