Hushed means quiet, as when people lower their voices. A hushed room, hushed tones, hushed and waiting.
It describes a quiet that people are producing rather than an absence of sound, which is why a hushed crowd is different from an empty one. Hushed up means kept quiet deliberately. Note hush, which is imitative — the sound is the instruction.
