For comparison, a vacuum cleaner runs at 70 decibels, a blender outputs 90 decibels and a motorcycle runs at 100 decibels. Dishwashers that include strainers rather than disposals, a common feature of European-made dishwashers, usually make less noise. Extra insulation and synthetic coatings also affect how quietly the appliances run. Dishwashers with lower decibel outputs usually command a higher price.
