Abstract
The auditory evoked potential (AEP) and the subjective preference for sound field were investigated as a function of the time delay (Δ t1) of sound field with single reflection. The stimulus was a female voice with 0.9 s duration and the delay was adjusted in a range of 0 to 125 ms. The information related to subjective preference appeared in the latency components, in which a relatively long-latency responses was observed at the most preferred delay. It is shown that the difference of latencies of AEPs over both hemispheres in response to a pair of sound fields with different delay contains almost the same information that is expressed by the subjective preference value obtained from paired comparison tests.
