The design of the dishwasher's interior, including the construction materials and insulation, is crucial for sound dampening. Thicker walls and better sound insulation reduce noise transmission. Finally, the placement of the dishwasher within the kitchen affects noise levels. Hard surfaces such as tile or granite will reflect sound, while carpeted floors and padded underlays can help absorb sound. Dishwashers also vary in their construction. Some models simply don't dampen noise well.
Dude, so many things make dishwashers noisy! The motor's a big one—cheap motors are loud. The pump matters too, and how strong the water spray is. The way it's built also matters a lot; some are just better at muffling noise than others. And finally, where it's placed in your kitchen makes a difference; hard floors make it louder.
