Abstract

Previously, it was reported that the most preferred initial time delay gap [Δt₁]_p and subsequent reverberation time are described by the minimum value of the effective duration (τ_e)_min of the running autocorrelation function (ACF) of music signals (2T = 2.0 s) (Y. ANDO et al. 1989 Journal of Acoustical Society of America 86, 644-649). This paper shows whether this result is supported or not by use of the electro-physiological method. Experiments were performed for sound fields changing the initial time delay gap Δt₁ of a single reflection with vocal music as a source signal, which has large changes in running τ_e, The results at the time interval when (τ_e)_minof the music is observed reveal that the scale value of subjective preference is closely related to the value of τ_e of the alpha wave obtained from the left heimsphere.
