This was a really recent realization for me. I am one of the people who can voluntarily activate the tensor tympani muscles in my ears to create a low level rumbling sound. I recently tried explaining this to someone else and they still think I am making it up.
Yep, the same sound as when you yawn. I can make it happen without yawning. Honestly, I can only make it for 5-10 seconds before I get “tired”.
Regarding clicks …I’ve no idea what that one is.
