Transverse pressure waves?

I still call it sound when I hear things under water. Gas isn't special.

When someone knocks on your door, you still say you heard the sound, even though the pressure wave was transmitted through the solid door material (before then being transmised to the gas in the room). Likewise, we still file a noise complaint when the neighbor is throwing a raging party, even though we are feeling the bass as much as we are hearing it.

And many old dogs, who may be totally deaf, can still hear/feel someone knocking on the front door. You don't need ears to detect vibrations.
