I agree we get to map definitions as we see fit. I propose we use the word “noise” for what you mentioned, and when the term gets longer it should refer to something more specific.

In the term “white noise”, the “white” refers to equal energy output in each wavelength, I believe. It’s distinguished from pink noise, brown noise, etc.

Of course, it should also refer to white nationalist propaganda, because there’s no way that could cause any confusion.

“I put a little white noise so I can go so sleep easier”
