Computer Synthesis and Evaluation of Noise Signal for Acoustic Measurements
In the field of architectural acoustic design, various kinds of acoustic measurements are necessary, therefore carrying and setting up of signal generators is inevitable. This problem can be resolved by introducing a compact disc, which contains a set of acoustic-measurement signals. For this purpose, the authors synthesized above-mentioned signals digitally by using a computer. Initially a uniformly distributed random sequence was generated by multiplicative congruence method, and Box-Müller transform and spectral shaping by FIR digital filters were applied.
