To find a relationship between subjective Preference and α-waves on The left and right cerebral hemispheres, an attempt is made here to analyze the autocorrelation function (ACF) of α-waves in relation to the delay time of single sound reflection. It is assumed that a similar repetitive feature of the α-wave range (8〜13 Hz) in terms of the effective duration of ACF is related to pleasantness or subjective preference. The results show that the effective duration of ACF from the left hemisphere is significantly changed according to the preferred delay (35 ms) or the echo disturbance (245 ms) condition (p < 0.01), but not from the right hemisphere. These effects reveal the left hemisphere dominance when one of the temporal factors of the sound field, the delay time of reflection, is changed (p < 0.05).
