Abstract:

It has been shown that the ASW for 1/3 octave band noise can be described as functions of the IACC and the W[inf IACC], which is defined by the time interval between values of 10% below the IACC [S. Sato and Y. Ando, J. Acoust. Soc. Am. 100, 2592 (1996)]. In this study, it is examined whether the ASW for music sources also can be calculated with the IACC and the W[inf IACC]. In order to control of both the IACC and the W[inf IACC], the delay time of two reflections relative to the direct sound was changed in the range of 0--50 ms. Results of the scale value of ASW obtained by paired comparison are compared with calculated ASW.
