在2个正弦音频率鉴别中测量的频率差阈值被认为小于在FM中测量的频率差阈值。在信号检测理论的框架内，提出了一种低调制频率的FM检测模型，该模型考虑了频率鉴别和FM检测之间的观测差异。FM检测模型预测人类心理测量函数，用于检测具有不同调制波形的FM。方形、正弦、梯形和三角形FM的FM检测与模型预测合理一致。
The frequency difference limen measured in a 2 sine-tone frequency discrimination is considered smaller than that measured in a FM. A model of FM detection for low modulation frequencies is presented, within the framework of signal detection theory, which considers the observed difference between frequency discrimination and FM detection. The FM detection model predicts human psychometric functions for detection of FM with different modulation waveforms. FM detection with square, sine, trapezoid and triangle FM are in reasonable agreement with the model predictions.
