Supplemental data of dependence of objective room acoustical parameters on source and receiver positions at field measurement

[摘要] References(11)Cited-By(3)Representative values of acoustical parameters in rooms for music performance are obtained from measurements in many halls. Discussed are the effects of source locations and positions of receivers on the results. The parameters studied are reverberation time RT, early decay time EDT, strength G, clarity C80, and interaural-cross-correlation coefficient IACC, which were measured using identical procedures, and where possible, according to international standard ISO 3382. Separate ranges and positions are suggested for symphony halls, chamber music halls and opera houses. It is indicated that the minimum number of positions given in ISO 3382 should be exceeded when measuring some parameters.
