Another way dishwashers are made quieter is by cycling the water in between the middle / upper spray arm and the middle / lower spray arms. Cycling the water between the upper and lower zones allows the machine to run a little quieter. Most dishwasher decibel ratings are around 56 decibels. Itâs tough to imagine what that sounds like if youâve never known what to listen for. There are many different comparisons- imagine something like a gentle breeze through tall trees. My parents have a 56 decibel rated Bosch.
