Data provenance: Sound levels (dBA) are taken from the EU EPREL energy-label registry, where airborne noise emission is a legally required, regulator-verified field on every dishwasher, washing machine and tumble dryer sold in the EU. We surface globally-sold brands and link each model to its official EU energy label. Model identifiers follow EU registrations; US model numbers for the same product can differ.
