Because it. mimics full-scale operation, system operators.

I can't figure out how to interpret my audiogram. I keep finding different standards for 'normal limits.' Some say it is 0-20 db, others 0-15 db. Some say it is 0-15 db for children and 0-25 db for adults.And yet others make it seem as though 0 db is the average threshold at all frequencies for 'normal hearing' young adults.he results themselves, however, fall in a bell-shaped curve, in exactly the same way that other human dimensions do (think average height, weight, age for example). The lower limits of what is considered normal gets influenced by how the information is going to be used.
