title: A general equation describing frequency discrimination as a function of frequency and sensation level.
abstract: Frequency-discrimination thresholds, for a wide range of stimulus frequencies and stimulus levels, were obtained from three normal-hearing listeners. Linear regression analyses of the present data, and of data from two previous studies, indicate that an SL-1 transformation of stimulus level and a square root F transformation of stimulus frequency yield linear dimensions that allow accurate predictions of frequency-discrimination thresholds from normal-hearing listeners over a wide range of stimulus frequencies (125-8000 Hz) and stimulus levels (5-8 dB SL) with a single prediction equation.
