How loud is a dishwasher?

A dishwasher is typically around 50 dB — comparable to moderate rainfall. That falls in the “moderate” band, safe for unlimited exposure.

People search “how loud is a dishwasher?” for two reasons: curiosity about the number, and a practical worry about whether it is doing damage. Here is both — the typical level, what it feels like next to sounds you know, and what to do about it.

What 50 dB actually feels like

50 dB is everyday-life loud: conversation, appliances and general activity all live in this band. It is completely safe for your hearing no matter how long it lasts, but sustained noise here is well documented to affect sleep, concentration and stress, which is why many residential noise ordinances draw their daytime line somewhere between 55 and 65 dB. In the specific case of a dishwasher, the figure depends a lot on distance and the exact source: measured close up it can be several decibels higher, and across a room several decibels lower. Treat 50 dB as a representative, real-world value rather than a fixed constant.

Noise-cancelling headphones

Active noise cancellation (ANC) cuts steady low-frequency noise — planes, trains, HVAC hum — by 20–30 dB, letting you listen at safer volumes.

Is a dishwasher dangerous?

At 50 dB, a dishwasher is safe for your hearing. It sits below the 85 dBA action level, so there is no cumulative hearing risk — although loud, sustained everyday noise can still affect sleep and concentration.

How to reduce it

Soft furnishings, sealed door gaps and a little extra distance all help. Because 50 dB is not a hearing hazard, the goal is comfort — reducing reflections and background hum rather than blocking dangerous peaks. See our soundproofing guide for what actually works.

Frequently asked questions

How many decibels is a dishwasher?
A dishwasher is typically about 50 dB, though the exact figure varies with distance, model and conditions. That places it in the “moderate” band of the decibel scale.
Is a dishwasher bad for your hearing?
At about 50 dB, a dishwasher is below the 85 dBA action level, so it will not damage hearing at any duration.
How does a dishwasher compare to normal conversation?
Normal conversation is about 60 dB. At 50 dB, a dishwasher is perceived as roughly 0.50× as quiet and carries about 10× less sound energy.
How can I make a dishwasher quieter?
Move further away, add soft furnishings to cut reflections, and seal gaps around doors — distance and mass are the two things that reliably help.
