I've had something like this, it was always a bunch of goo stuck in my
ear that could be fixed by hawking up whatever was stuck in my ear.
Not a pretty thing to talk about but it works.

Importantly and diagnostically, various “impulsive” INDIVIDUAL ACTIONS (vigorous head-shake, exhale, grunt) seem to interrupt the WWH for about ½ a second, after which it is found to have ramped back up.  This ramp-back-up timing reminds an audio engineer of AGC, which in turn might suggest actions of protective muscles in the middle ear (supposition here).
