As acoustical and vibration consultants, we are sometimes presented with what we call “non-physical criteria.” Non-physical criteria are usually predicated on the misunderstanding that it is possible to eliminate these contaminants. 

Nature’s LabAnimal journal has published an interesting collection of articles regarding experimental reproducibility in animal models. Unsurprisingly, confounding stressors like noise and vibration figure into the discussion. This is precisely Vibrasure's goal for design and monitoring in laboratory facilities: to minimize confounding variables, reduce the number of animals and time required to obtain good data, and improve animal welfare.
