What are the portable ac decibel levels?

Danby portable air conditioners have a sound rating from 38 decibels to 56 decibels.  The exact decibel range is determined by the model of the unit and the mode (fan, cool or heat if available with the model). Danby also has a patented Silencer Technology available on several models that will keep your home cool and comfortable while operating at a 46 decibel to 49 decibel range.
