Action potential (AP) tuning curves (TCs), generated by probe stimuli of 60-65 dB SPL with short rise and decay (r&d) times, are less sensitive (have elevated tip thresholds) and are detuned (the frequency is shifted away from that of the probe stimulus, towards a middle frequency of the audiogram). These effects are more pronounced with forward than with simultaneous masking. TCs generated by masking tonal and narrow band noise stimuli are nearly identical, even though the spectrum is much wider for the noise stimulus. Decreasing r&d time has the same effect on TCs generated from both noise and tonal stimuli, even when it only measurably increases the acoustic splatter of the latter. Detuning appears to be related to a temporal-intensity interaction.
由60 - 65 dB声压级的探测刺激产生的动作电位（AP）调谐曲线（TCs），其上升和衰减（r&d）时间较短，灵敏度较低（尖端阈值升高）且失谐（频率从探测刺激的频率偏移，朝着听力图的中频方向）。这些效应在正向掩蔽时比同时掩蔽时更明显。由掩蔽纯音和窄带噪声刺激产生的TCs几乎相同，尽管噪声刺激的频谱要宽得多。即使仅可测量地增加了后者的声学飞溅，缩短r&d时间对由噪声和纯音刺激产生的TCs具有相同的影响。失谐似乎与时间 - 强度相互作用有关。
