Is the sensation of pressure in the eardrum or the inner ear? Or both?

It's not tht localized.

Since the feeling is more physical than it is sensual, one expects that
it is in the middle ear or eardrum.. likely the same nerves that an
earache would stimulate.

It does seem localized somewhere in the ear. If the near-ultra sound is
loud enough, the sensation becomes sharply painful [not at all
"aching"] -- like when an airplane descends. Otherwise is just feels
like a wierd sensation of pressure or penetration.

If you are feeling a sensation of penetration, it's not due to ultrasound
and it's not located in your ear.

Near-ultrasound sine-waves resemble the barely-audible "scream" of a
CRT monitor. These sound are hardly perceived as auditory, rather they
are mostly felt in the ear as pressure. If loud enough, this
near-ultrasonic sine-wave can actually be sharply painful -- like
sticking a needle into the ear. Is this tactile sensation due to
stimulation of tactile receptors in the eardrum or inner ear?

You might perhaps soon need to consult an ENT.

Do not deal with useless questions. Your outer hair cells are obviously
at risk to get permanently damaged. Given you will catch a tinnitus,
then try to be its friend, otherwise it will be terrrible.
