Temporal integration of loudness of 1 kHz tones with 5 and 200 ms durations was assessed in four subjects using two loudness measurement procedures: categorical loudness scaling (CLS) and loudness matching. CLS provides a reliable and efficient procedure for collecting data on the temporal integration of loudness and previously reported nonmonotonic behavior observed at mid-sound pressure level levels is replicated with this procedure. Stimuli that are assigned to the same category are effectively matched in loudness, allowing the measurement of temporal integration with CLS without curve-fitting, interpolation, or assumptions concerning the form of the loudness growth function.
使用两种响度测量程序
类别响度标度（CLS）和响度匹配，对时长为 5 和 200 毫秒的 1 kHz 音调的响度的时间整合进行了四位受试者的评估。CLS 为收集关于响度的时间整合的数据提供了一种可靠且高效的程序，并且使用此程序复制了在中声音压级水平观察到的非单调行为。被分配到同一类别的刺激在响度上是有效匹配的，允许使用 CLS 进行时间整合测量，而无需进行曲线拟合、插值或有关响度增长函数形式的假设。
