Abstract
In some classical room acoustic criteria (e.g. C80, LG, IACC0,x, LF, JLF, JLFC) it is a standard practice to use a fixed temporal interval to quantify the weight of the early reflections versus the late reverberation. A value of 80 ms has been proposed in the literature also for opera houses. This paper, using the same approach of the previous literature, studies the temporal limit of integration in several Italian historical theatres. Early-to-late energy ratio and interaural cross correlation are tested and a new integration limit is proposed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
