A method is presented for simulating the impulse response between an acoustic source and multiple microphones in a reverberant room. The method is similar to the image method described by Allen and Berkley [J. Acoust. Soc. Am. 65, 943-950 (1979)] but includes modifications to simulate received echo arrival time accurately. The essential modification is to represent each received echo as a low-pass-filtered impulse at the correct arrival time. Using this "low-pass impulse" method, reverberant rooms can be simulated with sufficient accuracy to investigate multiple-microphone systems that are sensitive to interchannel phase.
提出了一种用于模拟混响室内声源与多个麦克风之间脉冲响应的方法。该方法类似于Allen和Berkley [《美国声学学会杂志》65, 943 - 950 (1979)] 所描述的镜像法,但进行了修改以准确模拟接收到的回声到达时间。关键的修改是将每个接收到的回声表示为在正确到达时间的低通滤波脉冲。使用这种 “低通脉冲” 方法,可以足够精确地模拟混响室,以研究对通道间相位敏感的多麦克风系统。
