本研究在改变自相关函数(ACF)的情况下，考察了中心频率为250、500和1000赫兹的带通噪声的响度。通过2068分贝/倍频程的锐化滤波器改变源信号的带宽，以控制源信号的ACF。用配对比较法得到响度的尺寸值。结果表明，在临界带内，带通噪声的响度不是恒定的。纯音的响度大于经过大幅滤波的噪声。带通噪声的响度随源信号的ACF(τe)有效持续时间的增加而增加。
This study examines the loudness of bandpass noises with center frequencies of 250, 500 and 1000Hz while changing the autocorrelation function (ACF). The bandwidth of the source signal was altered with a 2068 dB/octave sharp filter to control the ACF of the source signal. The scale values of loudness were obtained using a paired-comparison method. It is shown that the loudness of the bandpass noises inside the critical band is not constant. The loudness of the pure tone is greater than that of sharply filtered noises. The loudness of the bandpass noises increases with increasing effective duration of the ACF (τe) of the source signal.
