频率辨别力的测量频率从200-8000 Hz和5-80 dB的感觉水平，使用脉冲正弦波作为刺激，在自适应2间隔力选择心理物理程序。方差分析表明，频率和感觉水平，频率和感觉水平之间的相互作用的显着影响。感觉水平的影响在低频最大，在高频下降，在8000赫兹相当小。这些数据用于评估当前理论模型的预测。
Frequency discrimination was measured for frequencies from 200-8000 Hz and for sensation levels from 5-80 dB using pulsed sinusoids as stimuli in an adaptive 2-interval force-choice psychophysical procedure. An analysis of variance indicated significant effects of frequency and sensation level, and of the interaction between frequency and sensation level. The effect of sensation level was greatest at low frequencies and decreased at high frequencies, being quite small at 8000 Hz. The data were used to evaluate the predictions of current theoretical models.
