Strange pulsating of eardrum

Hi

Does anyone else experience the symptom of the eardrum pulsating to certain pitch of sound.

Its not present all the time and the sound trigger does not have to be loud just the TV or radio on will trigger it but it does seem to be at a certain pitch. Sometimes also sounds like a bumble bee buzzing for a second by my ear can’t count the amount of time I have swiped my hand by my ear as if an insect was there…

Puzzled?
