Quick Answer. When talking about dishwashers, decibels refers to the noise level a dishwasher produces when it is in operation. The quietest dishwashers have decibel ratings around 40 and slightly below, while the noise level in decibels of a normal conversation is about 60.
Supplementary convenience features in dishwasher models can also contribute to the overall noise level of the machine. Extra features such as disposal systems, additional spray arms, added jets, and certain dishwasher filters can all make a big difference in the decibel rating of your appliance.
