Mapping decibel range to linear audible intervals I am working in an engine that encodes sound as decibels (dB). Let's assume the decibel range of human hearing is 60dB to 0dB. Audibility is not linear across this range. So my question is... How does one map a decibel range to a set of numbers (for example, 1 10), such that each number corresponds to (roughly) one linear step up in audibility?
