Is 48 decibels loud for a dishwasher?

The dishwasher noise is rated in decibels. A dishwasher that is just one decibel louder is 30 percent louder. Is this true? It is not loud to buy a dishwasher at 44DBs.The noise levels of the dishwasher are rated in decibels, the smaller the number of decibels the quietest of the dishwasher. A difference of only a few decibels may seem not much, but a dishwasher that is just an extra decibel is actually 30 percent stronger. However, buying a 44 dBs dishwasher is quite quiet.
