Dear List,

When terms like critical bandwidth or just-noticeable-difference are used,
what is their statistical foundation?

For instance, if I say that the JND for pitch is 5 cents (at a given
frequency, for a sample), for what percentage of responses would I expect
would I expect to get a "yes the pitch has changed" answer?
