Abstract

The characterization of acoustic spaces by impulse response measurements is often biased by the nonlinear behavior of the loudspeakers that excite the test system. While the use of swept techniques can significantly reduce the consequences of nonlinearity artifacts, such signals cannot avoid distortion degradation in the causal part of the measured impulse response. This conclusion is based on a new interpretation of the nonlinear effects using theoretical analysis, computer simulations, and direct measurements.
