Could a form of acoustic levitation be used as artificial gravity?

So I heard about this thing on vsauce a while ago, where scientists use this thing called "acoustic levitation". They use ultrasonic frequencies to levitate various substances, for use of studying their properties in an isolated environment.

But I had a thought: if sound can push against gravity and cause objects to levitate, could it possibly push against an object, sending it away from the source of the sound? To be more specific, could ultrasound speakers be installed in the ceiling of a spaceship, and push its occupants towards the floor, simulating gravity?

Would this work? And what would be the possible side effects on the human body?
