This paper defines the minimum value of the effective duration of the running autocorrelation function of a music signal used in subjective preference testing. A short duration signal, which may relate to ‘‘psychological present,’’ is more suitable for calculating the most preferred time delay of the single reflection than is the long‐time autocorrelation function. This fact is found particularly when passages of Japanese music are being played, which include a wide‐range‐noise component at the very beginning of the signal and the so‐called ‘‘MA.’’ MA is a stationary sound passage without any rapid movement. This paper also shows that, for subsequent reverberation time, a flat frequency response may be in the range of preferred conditions. Such preferred conditions may be calculated by the minimum effective duration of the running autocorrelation function of source signals after passing through the A‐weighting network.
