AB  - The time required for measuring the spatial features of sound sources and receivers can be decreased by using test signals composed of multiple exponential sweeps. But any such technique must include the influence of nonlinearities at modest signal levels. This research expands on a strategy to overcome interference between the components created by system nonlinearity and those that are part of the system impulse response. Previously, the so called multiple exponential sweep method (MESM) has been proposed using a combination of the two strategies, overlapping and interleaving. This method is modified by introducing a generalized overlapping method and further consideration of the fine structure of the impulse responses to be measured. This method can yield shorter measurement times than the original method without loss of accuracy.
