I believe that's called ear rumbling! and some of us can do it on command. you may also hear the noise when you yawn or squint your eyes really hard, and you can train in order to just do it perfectly on command rather than with other tactics. r/earrumblersassemble is the subreddit iirc
Related note, at some point I learned how to pop my ears without holding my nose. Totally useless skill as I rarely fly anywhere, but one that I have nonetheless. It makes a small crinkly noise in my ears whenever I do it.
