Dishwasher models that produce 41 to 50 decibels are almost silent, and stainless steel tubs are generally quieter than plastic tubs. Bosch dishwashers are the quietest in the U.S. when compared to other full-size stainless steel tub dishwashers from major brands, as stated on the official Bosch website. These machines use an Eco Silence brushless motor system to reduce noise by 25 percent, and they include several layers of noise-absorbing insulation as well as a molded base to reduce vibration. The filtration system eliminates the need for a noisy food disposal, and the spray arms reduce noise by spraying water towards the dishes. Most Bosch dishwashers range from 38 to 42 decibels.
KitchenAid has replaced soft disposers with filters in its dishwashers to reduce noise, and the quietest dishwasher from the brand produces 37 decibels, as of 2015. KitchenAid dishwashers also feature the best drying system among leading premium brands, according to the official KitchenAid website. The WhisperQuiet system features high-quality sound insulation to reduce noise.Learn more about Dishwashers
