I recently replaced a builder-grade dishwasher with a new one. My first criteria was that it be quiet, so that I didn't have to turn up the TV volume in the next room. I found a GE that operates at 45 dB and I can barely notice it. Bosch have traditionally been very quiet - so much so that they have a light that shines on the floor to let you know when the cycle is complete. Some of the new Whirlpool ones are slightly quieter than the Bosch for a lot less money. Note that many models use the same internals, so you don't have to pay for a prestige brand.
