在消声室中进行了四个实验，以研究持续时间，信号间隔，重复和频率对脉冲信号感知噪声的影响。所有的数据收集的自适应心理物理程序称为参数估计序贯测试（PEST）。主要结论是：（1）脉冲信号的相位谱与其感知的噪声无关，以及（2）耳朵对脉冲信号噪声的敏感性类似于能量求和过程;即，它似乎将噪声事件的总声功率积分到至少100秒。
Four experiments were performed in an anechoic chamber to investigate the effects of duration, intersignal interval, repetition, and frequency on the perceived noisiness of impulsive signals. All data were collected by an adaptive psychophysical procedure called Parameter Estimation by Sequential Testing (PEST). The major conclusions were that (1) the phase spectrum of an impulsive signal is irrelevant to its perceived noisiness, and (2) the ear's sensitivity to noisiness of impulsive signals resembles an energy summation process; i.e., it appears to integrate total acoustic power of noise events to at least 100 sec.
