The result of low pass filtered frequency domain division then taking the inverse Fourier transform for system impulse responses measured at microphones 2 and 1 with a sample rate of 96 kHz. (a) The beginning of the time axis shows the transfer function is followed by a decaying series. (b) The initial pulse occurs at the start of the time axis (c) with ripple extending to the end of the time axis.
