| 摘 要： | 对不同持续时间 1 k Hz纯音的强度 JND的测量表明 ,Weber比随信号持续时间的增加而减小 ,减小的速度随信号持续时间的增加而减缓 ,到信号持续时间增加到 5s时 Weber比不再随信号持续时间的增加而减小 ,此时 Weber比随强度的变化与 Weber定律极为接近 ,而与内部泊松内部噪声 ( PIN)理论、以及饱和内部泊松内部噪声 ( SPIN)理论的预期严重背离

| Abstract: | The measurement of intensity JND for 1kHz tone bursts of various durations show that Weber fractions decrease with duration increasing and reach to asymptote till 5 seconds. The relations between Weber fraction and intensity are very close to Weber's law, but severely depart from Poisson Internal Noise theory and Saturation Poisson Internal Noise theory. |
