Item An investigation of acoustic impulse response measurement and modeling for small rooms(Montana State University - Bozeman, College of Engineering, 2007) Chen, Zhixin; Chairperson, Graduate Committee: Robert C. MaherRoom impulse response modeling has been a subject of interest to acousticians, musicians, and architects for many years. Room impulse response modeling can help to predict the acoustical characteristics of the new finished concert halls, to create a virtual studio effect for music production without building the actual studio room, and to compare the effect of different absorbing materials and treatments in architecture. The goals of this dissertation are to obtain a better match between the simulation and the measurement results of small room impulse responses, and to understand why the models and the measurements may differ even for simple cases like small rectangular rooms. The basic image source method and digital waveguide mesh are widely used in modeling small room impulse responses because they are relatively easy to implement.
