The Huggins pitch effect is created by dichotic broadband noise with interaural phase varying from 0 to 2 pi over a narrow frequency region. The sensation of pitch, corresponding to the frequency of the phase shift region, is usually understood as the result of a binaural differencing operation. We report here a pitch effect created by dichotic broadband noise with interaural phase varying from 0 to pi over a narrow boundary region, creating an edge in a difference channel. We call this effect Binaural Edge Pitch. For experienced listeners the effect is similar in nature and strength to the Huggins pitch. It is strongest for boundary frequencies in the 350--800 Hz range. Pitch matching experiments in this range find that the spread of matches in 1%--2% of the boundary frequency and that the pitch is 4% higher or lower than the boundary frequency. This shift is identical to the shifts which we find for the pitch of high-pass and low-pass noise bands. The correspondence argues strongly for an explanation of the Binaural Edge Pitch in terms of the Equalization--Cancellation Model of binaural processing, and pitch derived from central spectrum.
哈金斯音调效应是由双耳宽带噪声产生的，在一个狭窄的频率区域内，双耳相位从0变化到2π。对应于相移区域频率的音调感觉通常被理解为双耳差分运算的结果。我们在此报告一种由双耳宽带噪声产生的音调效应，在一个狭窄的边界区域内，双耳相位从0变化到π，在差分通道中形成一个边缘。我们将这种效应称为双耳边缘音调。对于有经验的听众来说，这种效应在性质和强度上与哈金斯音调相似。在350 - 800赫兹范围内的边界频率处最强。在这个范围内的音调匹配实验发现，匹配的范围在边界频率的1% - 2%，并且音调比边界频率高4%或低4%。这种偏移与我们在高通和低通噪声带音调中发现的偏移相同。这种对应关系有力地支持了根据双耳处理的均衡 - 抵消模型以及从中央频谱导出的音调来解释双耳边缘音调。
