An improved model for loudness coding during auditory adaptation.

Abstract

A comparison of loudness adaptation measured at four baseline intensities and at test values 10 and 20 dB above the baseline intensities revealed an orderly decline. The magnitude of the decline in loudness adaptation with the increasing difference between the test values and the baseline was shown to agree with earlier theories. A method for closely estimating the change in loudness adaptation is presented in convenient graphic form and in algebraic equations.
