The development of a system for room acoustical measurements and analysis is described. The goal of the project was a versatile system for multi-channel and binaural investigations of room and concert hall acoustics. It consists of a portable PC-based workstation with multi-channel AD/DA data acquisition, an omnidirectional sound source, a 3-D microphone grid for directional response registration, a dummy head, standard omnidirectional and cardioid microphones, and MLS-based response computation. In addition to traditional room-acoustical attribute analysis, special algorithms have been developed to investigate the time-frequency behavior of responses in different directions, for example in concert halls. Analysis cases of interesting hall measurements are discussed.
