This drove me crazy for a while, because I can do it- but I didn’t know what it was and I couldn’t figure out how to describe the rumbling sound in my ears. It usually happens when I shut my eyes super tight. Glad to see that I’m not alone, and that there’s a good explanation of what it is!
can everyone not do this??? i thought that hearing a rumbling static noise from the muscles in your ears when you squeezed your face shut really hard was universal
