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.

    When you yawn sometimes you hear a little clicking noise in your ear canals, it's earwax coming into contact briefly and separating, you can do it voluntarily similar to rumbling but I need to open my jaw a little for that effect
