The sensitivity of listeners to early sound field changes in auditoriums

摘要: The sensitivity of listeners to small changes in the early sound field auditoria has been measured. This was done using a realistic artificial simulation system concert ball field. designed so that standard objective parameter values were typical those found real halls, and within ranges known be subjectively preferred. following difference limens measured: lateral energy fraction; inter-aural cross correlation coefficient; clarity index centre time. From these results it shown when are made field, perceived spatial impression will usually larger than for clarity. Furthermore acousticians can gain most by paying attention sound. Other measurements showed that: (i) initial time delay gap is not significant listener preference, (ii) diffuse reflections differently from specular reflections.
