Miele prides itself on exacting standards to ensure uncompromising performance, such as offering a dishwasher that will not only outperform, but also significantly outlast others on the market. Superior performance, however, is only achievable when balanced with the comfort and peace-of-mind of whisper-quiet care.
To gain insight into the relationship between performance and sound, Miele commissioned Owens Corning Acoustics Research Center (OCARC) to conduct independent comparative testing. Tests were conducted on both 'clean' loads and 'soiled' loads.
When soiling was introduced (simulating a true, at-home application), a leading manufacturer, who aggressively promotes low sound levels, recorded an increase of 6 decibel levels as compared to advertised sound levels. A significant and audible difference, given that noise levels double with every 3 dBas. Miele, however, measured up to the same, no matter whether the load was clean or soiled. No increase in decibel levels was reported, despite the performance requirement changes necessary to successfully handle the cleaning task at hand.
What was heard? The SoundTruth™ of a Miele dishwasher.

With other brands, soiling leads to increased pump activity, water disbursement and energy consumption. The result is a louder, less efficient dishwasher. It is the combination of an advanced insulation system, multiple turbidity sensors and a proven pump that ensures Miele consistently and efficiently manages sound. Meaning that clean loads and soiled loads yield the same decibel level or…SoundTruth™.
Miele not only guarantees SoundTruth™, but in fact delivers America's quietest dishwasher! Independent tests report the sound emission of Miele's Futura Diamond dishwasher - with and without soiling - at 37dBa. Simply stated, no other dishwasher performs better or quieter than Miele. And if you are not completely convinced that your Miele is the quietest and best-cleaning dishwasher you have ever owned, we will fully refund your purchase within 90 days.
