Doubt it but I've forgotten most of what I've heard(!) about the

Not 'pseudohallucinations.' It's entirely possible to stimulate the
haircells with temporal (or any cranial) bone vibration.

Nerves cannot fire at more than 1KHz at the very most, so any direct
stimulation would be bandwidth limited. In addition, it is unlikely
that peripheral nerve stimulation (<1Khz) will reach auditory cortex.
That said, direct stimulation is a standard diagnostic tool for
testing peripheral nerves.
