Can we simulate sound? (self.asklemmy)

I know that nowadays there are some physics engines pretty advanced, capable of very complex simulations.

Are we at a point in technology where if, for example, we were to simulate a rock being dropped on the floor from a certain distance, the simulation can calculate the shape and weight of the rock , the air resistance experienced during the fall, the density of the floor where the rock will fall onto, and all the other thousands of factors involved, and from those things "calculate" the sound that the rock will make when hitting the floor, and then reproduce it?

Is there such a thing? Are we there yet? If not, is it something feasible?

Not specifically for a rock, but that's "roughly" how physical modeling synthesiers work for instruments.

Also there's a youtube channel of a guy who builds an engine simulator to reproduce the sounds of 4-stroke and 2-stroke engines by applying fluid dynamic simulation of the gas flows in an engine.

It COULD conceivably be built for rock dropping as well, but I assume that's not a thing people have yet put effort in.
