哈金斯音调效应是由双耳宽带噪声产生的，耳间相位从0到2.pi变化。在一个很窄的频率范围内。与相移区的频率相对应的音调感觉通常被理解为双耳差分操作的结果。报道了由双耳宽带噪声产生的音调效应，其耳间相位从0变化到.pi。在狭窄的边界区域上，在不同的通道中创建边缘。这种效应被称为双耳边缘音高。对于有经验的听众来说，这种效果在性质和强度上都类似于哈金斯的音高。对于350-800赫兹范围内的边界频率，它是最强的。在此范围内的基音匹配实验发现，匹配的扩展为边界频率的1-2%，并且基音比边界频率高或低4%。这种漂移与高通和低通噪声频段的音调漂移相同。该通信强烈支持用双耳处理的均衡-抵消模型来解释双耳边缘音调，以及从中心频谱得出的音调。
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. A pitch effect created by dichotic broadband noise is reported with interaural phase varying from 0 to .pi. over a narrow boundary region, creating an edge in a difference channel. This effect is called 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 is 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 are found 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 a central spectrum.
