When shopping for a dishwasher, there are plenty of factors to consider: wash cycles, adjustable racks, and energy efficiency. However, one of the most popular features is its decibel level. While most dishwashers tend to have similar decibel levels, just one decibel can make a huge difference: a single decibel increase is actually 30 percent louder.
When researching dishwashing appliances online, here are some features that will determine how noisy a dishwasher can be:
Insulation is installed along the sides, top and the door of the dishwasher. Proper insulation not only reduces noise but also improves energy efficiency. Look for dishwashers with an Energy Star rating and/or quiet operation features as these units have sufficient insulation.
Sound Dampening Material
There are additional sound-deadening materials that can be installed around a dishwasher to dampen the noise, especially if you own an older model. These materials can be attached with construction adhesive or silicone sealant along the sides and tops of the dishwasher.
Stainless Steel vs. Plastic Tubs
Stainless steel tubs are quieter than plastic tubs because the stainless steel absorbs noise better. While stainless steel models tend to have a higher upfront price than plastic models, you will save long-term costs due to its ability to better retain heat and increase the efficiency of the drying cycle.
So while a decibel rating above 60 could be deafening, dishwashers with a rating in the 40s are virtually silent. Here is an abbreviated list of the most popular dishwasher models currently available at Appliances Connection and their decibel rating:
