Application of analytic sweep segments in room acoustic measurements
Csaba Huszty, Sakae Yokoyama, Shinichi Sakamoto · 2010
Room acoustic measurements employing indirect signals to obtain room impulse responses are widely used nowadays, particularly swept sine signals. In this paper, application of a general method creating excitation signals solely in time-domain with sigmoid, monomial power function and generalized exponential modulation functions are presented. By using such signals it is possible to match different optimization criteria such as customizing the SNRfrequency function of the resulting room impulse response and obtain useful results in a wider frequency region where excitation signal is present. Theoretical and practical aspects are presented with measurement results and total harmonic distortion (THD) response analysis.
