本文介绍了一种算法，模拟一个移动的声音图像作为一个随时间变化的声学事件和报告的结果的调查方法的插值双耳响应。由于运动的声音图像需要大量的双耳响应，因此使用插值方法是必要的。我们研究了两种插值方法，一种是考虑初始时间延迟差的线性波形插值方法，另一种是使用响应的最小相位分量和耳间时间差模型的线性插值方法。通过使用该算法模拟的双耳信号的频谱图的方法进行评估。结果表明，考虑初始时延差的线性插值方法具有较高的插值精度，且两种方法均能保持耳间时延差。
This paper introduces an algorithm simulating a moving sound image as a time-variant acoustic event and reports on the results of an investigation of methods for interpolation of binaural responses. As moving sound images require numerous binaural responses, the use of interpolation methods is necessary. We investigated two interpolation methods; one is a linear waveform interpolation method considering of initial time delay difference and the other is a linear interpolation method using the minimum-phase component of a response and an inter-aural time difference model. The methods are evaluated by using a spectrogram of binaural signals simulated by the algorithm. The results showed that the linear interpolation considering the initial time-delay difference resulted in highly precise interpolation and that the inter-aural time difference was maintained in both the methods.
