Had someone ask me this recently - and I talked around the actual question a bit. Sampling techniques for instance can provide similar results. Visual special effects are in constant demand (where physical scene creation can be expensive or dangerous) while most audio effects can be created cheaply and safely. Still, it is an interesting question - when you boil it down to physics, it's all just waves y'know :).
