Vibrasure presents audiograms for four different mammals that might be of interest. Exact species vary, but these data may be taken as representative for rabbits, rats, mice, and small primates. The data is then compared with the human audiogram for comparison.
How instrument criteria are developed: regimes of interference
In a previous post, we wrote about how realistic laboratory vibration criteria for sensitive tools like electron microscopes could be developed from data relating performance to vibration level. Having real data is important for both customers and consultants, since non-physical criteria aren’t helpful to anyone. In this post, we discuss where a useful criterion might fall on that curve.
How instrument criteria are developed: “error-vs-vibration”
Many laboratory instruments are exquisitely sensitive to “energetic contaminants” like vibration, noise, and electromagnetic interference. It’s not always easy reading and interpreting these criteria; they’re sometimes confusing even to vibration consultants. But to be honest, it’s not easy developing them, either. So, where do these criteria come from, and what do they mean? We explore more in this blog post.
