Abstract
The method and system for measuring low-noise acoustical impulse responses at high sampling rates of the present invention utilizes two exponential sine sweeps (ESSs) to measure the impulse responses. The first ESS is a quick sweep up to the Nyquist frequency to provide an estimate of the system response and sample the ambient noise. This measurement is used to algorithmically determine an appropriate pass-band of the system. A second, slower sweep through the pass-band alone is then executed and a corresponding band-pass filter is applied to the resulting output signal to suppress noise. The result is a measured impulse response with an improved signal-to-noise ratio and a much-reduced pre-response.
