I like the audio approach. It should make it possible to measure rotation speed under load. Even a Vitamix slows down a bit when powering through stuff. This might provide a way to compare different blenders in terms of quality. A good blender and a cheap blender might have the same top speed, but the good blender will have more torque and slow down less when meeting resistance.
