Our home is built with an open concept.  It came with a builders grade dishwasher that was so loud we had to max the volume on the TV when it was running.  My wife found the Bosch Benchmark dishwasher, advertised as quiet (38db) to replace ours.  It was also advertised to dry everything (even plastic) completely.  Furthermore, you can put plastic on the botton rack without it melting.  We put it to the test.  You can hardly hear it running except for the gurgle in the drain when it is draining water.  It will dry everything completely as long as you place items such that water does not puddle in the surface.  And you truely can put plastic on the bottom rack without damage.  We are very happy with our purchase.
