Well, there is a speed of sound on the moon. Sound does travel through the regolith. If you were standing on the moon you would indeed "hear" this impact as the sound moved up through your feet. It would sound/feel like standing beside a subwoofer.

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.
