What is Dishwasher dBA?

The noise produced by most appliances, including dishwashers, is calculated in dBA. This stands for “A-weighted decibels” and is used to measure how loud a noise will sound to most people.

There is one principle to understanding dishwasher dBA: the higher the dBA level of a dishwasher, the noisier the appliance will be.

How Many Decibels is a Quiet Dishwasher?

One question often asked is if a 50 dBA dishwasher is quiet?

It’s up to you to decide if this could potentially interfere with your daily life, whether that means disrupting your sleep or preventing you from having a conversation near your kitchen.

As a guideline, any dishwasher with a decibel level of 44 dBA or lower is generally considered quiet. The quietest models can be as low as 38 dBA, and are considered practically silent.

How to Buy a Quiet Dishwasher

Due to innovations that include improvements in sound insulation and quieter motors, among others, many new dishwashers have lower dBA levels.

Some of the factors that may contribute to a dishwasher’s noise level include:

The quality of materials  may make a difference for noise output. Also, the thickness of the insulation may impact the decibel rating.

Remember that a dishwasher with a stainless steel tub should produce less noise than a dishwasher with a plastic tub. Furthermore, sound dampening on the outside of the tub can help reduce noise.

Water movement contributes to the noise level a dishwasher makes. The process where water is pumped into the dishwasher, then cycled through before being pumped out again, creates a lot of the noise that is produced. Dishwasher manufacturers have been able to minimize this noise through innovations in wash cycles, the speed and the amount of force used to spray water, and by implementing quieter pump systems into modern dishwashers.

Dishwashers that come with a food disposal are often noisier than those without one. You can always choose to purchase a dishwasher with an easy-to-clean food trap system to help ensure that the dishwasher is relatively quiet when operating.

PRO TIP: If your dishwasher is too loud or an older model, you may be able to install insulation in the form of sound-deadening material to reduce the noise.

Dishwashers should make your life easier by washing loads of dirty dishes, bowls, cutlery and mugs without disrupting your life by being too loud.

We hope you better understand dishwasher dBA now and feel well equipped to make a more informed purchase.
