Pitch shifts in sinusoids as a function of intensity result in systematic response biases and differences in performance in forced-choice frequency-discrimination tasks. Two approaches are described for converting these effects to a measure of pitch shift in Hz using standard signal-detection-theory assumptions. To illustrate these approaches, forced-choice frequency-discrimination data were obtained for three listeners at 250 and 4000 Hz, with six intensities from 40 to 90 dB SPL. The resulting pitch-shift estimates are in good agreement with adjustment data obtained from the same listeners. Collection and analysis of the forced-choice data can be greatly simplified by using an adaptive procedure. Pitch-shift estimates obtained in this way for two of the three listeners are in good agreement with the other estimates.
正弦波中音调偏移作为强度的函数，会在强制选择频率辨别任务中导致系统的反应偏差和表现差异。描述了两种方法，可利用标准信号检测理论假设将这些效应转换为以赫兹为单位的音调偏移量度。为说明这些方法，针对三名听者在250赫兹和4000赫兹频率下，以及40至90分贝声压级的六种强度，获取了强制选择频率辨别数据。所得的音调偏移估计值与从相同听者处获得的调整数据高度一致。通过使用自适应程序，可大大简化强制选择数据的收集和分析。以这种方式为三名听者中的两名获得的音调偏移估计值与其他估计值高度一致。
