Three experiments showed that dynamic frequency change influenced loudness. Listeners heard tones that had concurrent frequency and intensity change and tracked loudness while ignoring pitch. Dynamic frequency change significantly influenced loudness. A control experiment showed that the effect depended on dynamic change and was opposite that predicted by static equal loudness contours. In a 3rd experiment, listeners heard white noise intensity change in one ear and harmonic frequency change in the other and tracked the loudness of the noise while ignoring the harmonic tone. Findings suggest that the dynamic interaction of pitch and loudness occurs centrally in the auditory system; is an analytic process; has evolved to take advantage of naturally occurring covariation of frequency and intensity; and reflects a shortcoming of traditional static models of loudness perception in a dynamic natural setting.
三项实验表明，动态频率变化会影响响度。听众听到同时发生频率和强度变化的音调，并在忽略音高的情况下追踪响度。动态频率变化显著影响响度。一项对照实验表明，这种效应取决于动态变化，且与静态等响度曲线所预测的情况相反。在第三个实验中，听众一只耳朵听到白噪声强度变化，另一只耳朵听到谐波频率变化，并在忽略谐波音调的情况下追踪噪声的响度。研究结果表明，音高和响度的动态相互作用发生在听觉系统的中枢；是一个分析过程；已经进化到利用频率和强度自然发生的协变；并反映了在动态自然环境中传统响度感知静态模型的一个缺陷。
