I think they're all labeled with a noise level or a quietness level on them at the store. That's definitely important to look at. Our house was a spec house, so the developer picked out our dishwasher, so now we're stuck with THE WORLD'S NOISIEST DISHWASHER and an open floor plan, so it's just terrible! It's whirlpool or something, so it's a good brand, but it's so LOUD!!!
