Before you buy a new dishwasher, letâs take a closer look at what a dishwasher âdecibel ratingâ means and why you should be paying attention to it. A decibel (dB) is a logarithmic unit that is used to describe levels of sound. Often decibels are measured as dBA units, which filter out higher and lower frequencies to be more representative of the way humans can hear. Using dBA units, sound monitors can accurately reflect what noise frequencies the human ear will be sensitive to.
