In general: it's no surprise that there is a general bias towards higher-frequency sensitivities in animals. That's why we often have to measure (and speak) in terms of ultrasound when it comes to animals. A general rule of thumb holds that for mammals, frequency is inversely-proportional to size. 

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.

Anyone who has designed animal laboratory spaces realizes that the animals have unique needs. One problem that comes up often with animal facilities is designing them for reasonable acoustics and noise control. Just like our human customers, we want our animal customers to have safe and comfortable places to live.
