Separability of Distortion Products in Room Impulse Response Measurements with Maximum Length Sequences
In the room impulse response measurements, one of the common disturbances affecting the measured results is nonlinearity. When maximum length sequences are applied for the measurements, the distortion products are distributed along the estimated impulse response. While this property of maximum length sequences has been widely used in the auditory system applications for characterization of a nonlinear system, it has not been exploited in room acoustics. Due to this reason, the possibility of separating the distortion products in the measurements of the room impulse responses with maximum length sequences is analyzed in this paper. The results show that this measurement method is sensitive to nonlinearities, but the separability of the distortion products could reduce the nonlinearity effects.
