How Is Dishwasher Noise Measured?
What Makes a Dishwasher Quiet?
- Movement of Water: When water flows into the dishwasher, it is cycled through and then pumped out again, causing much of the sound you hear. There are a number of dishwasher manufacturers that minimize these noises with innovations to wash cycles, the amount of force and speed used to spray water, and quieter pump systems.
- Insulation: The quality and quantity of insulation on the exterior of a dishwasher has a significant impact on its noise output.
- Disposal Feature: Noise levels will be higher for models with food disposals than those without. These days, many dishwashers come with a food trap system that is easy to clean and results in a quieter dishwasher.
- Tub Materials: Plastic tub dishwashers are typically louder than stainless steel tub dishwashers. In addition, sound dampening on the outside of the tub helps to reduce noise. For example, a unique feature from KitchenAid® is that all their dishwashers feature a stainless steel tub with excellent sound dampening that also resists streaks, stains and odours while retaining heat to help improve drying performance.
Types of Quiet Dishwashers
For those who frequently cook up a feast, look for a dishwasher that has a third rack so you can combat mess-making with three racks of versatile loading options. By adding extra space, you are able to store glasses, mugs, bowls, spoons, silverware, and cooking tools, allowing more room underneath for pots, plates, and mixing bowls. All of these features are available with a 44 dBA rating, which is still quiet enough to let you carry on a conversation or enjoy a meal that has just been prepared without any interruption, even in open-concept kitchens.
