As a primitive objective parameter of sound fields in rooms on subjective evaluations, the degree of interauralcross correlation (IACC) is being widely accepted as well as the listening level, the initial time delay gap between the direct sound and the first reflection and the reverberation time. The aim of this investigation is to determine contributions of the level and the IACC, and the independence between the both parameters on the subjective preference judgements. In oder to change the two parameters being kept other ones constants, sound fields were simulated by the aid of a computer with the Schroeder's reverberator. Results of the paired-comparison tests show that:(1) Preferred listening level depends upon the source music played, but the IACC. (2) Scale values of preference of sound fields decrease with increasing degree of the IACC, but they are independent of the listening level and the music. (3) The listening level and the IACC affect independently on the subjective preference, so that the scale value of preference of a given sound field can be obtained by adding the average scale values with respect to each parameter.
