Blendtech Professional 800 Blender
This is called the worlds quietest blender, and at about 50 decibels of noise (about the same sound level as the average human conversation) the Blendtech Professional 800 Blender reigns supreme.The Blendtech Pro 800 will cost you more than 10 times what a regular standard blender costs, but if you don't like loud noise when blending, this is the one to have. The 3.8 horsepower motor will make short work of grinding ice, it has six presets for making things like delicious smoothies, cake batters, nutricious juice, and it will even make hot soup. The digital touch speed slider gives you 11 speeds plus a pulse function, and the entire display panel is illuminated. The Blendtech Professional 800 can't be beat for quiet performance and features an eight year warranty. If quiet performance is what you're after (and you're willing to pay for it) then this blender must be first on anyones list.
