I’m wondering if this is something different, or if it’s a more intense level of the other thing. I’m able to pop my ears without any apparent tensioning of my jaw or a yawn reflex. But I can do it while also making the rushing sound or not.
Yeah, it's two different muscles for the rumbling vs clicking. Tensor veli palatini opens the eustachian tube and makes a click. The rumbling is from the tympani.
