This model comparison video tests the relative noise levels during operation of several popular high-performance blenders. Featured are the OmniBlend V, the Blendtec Total Blender, the Vitamix Professional Series 750, and the Vitamix 5200. The Pro 750 is representative of all of the Vitamix “Next Generation” models, and the 5200 is comparable to all “traditional” models in the Vitamix home line of blenders.
A test is run using identical ingredients in each blender. The viewer can gauge the relative differences in noise levels simply by listening. As well, a sound meter is used on each blender.

Per the sound meter, the Blendtec Total Blender registered the highest decibel output, followed by, in order, the Vitamix 5200, the OmniBlend V, and the Vitamix Professional Series 750. Though the differences in sound output are audibly apparent with the Blendtec Total Blender being the loudest model of those tested, the differences in noise levels between it and other models is not as drastic as numerous claims infer.
