抄録

The aim of this study is to develop a listening test method that would be suitable for investigating the effect of sound absorption on the comfort provided by sound environments in residences. To accomplish this, listening test methods that employ an actual scale room model and ones that employ binaural recording and headphone reproduction were compared. Through this comparison, the following clarifications have been achieved: 1) Results obtained through binaural recording and headphone reproduction were almost the same as those obtained using the actual scale room model. 2) Moving a dummy head microphone to simulate a subject's walking in an actual room was useful for reproducing a “sense of reverberation” because recorded footsteps help the subject's judgments. 3) The psychological factors, “sense of silence,” “sense of reverberation,” and “feeling of serenity” were not influenced by the personal preference of the subject, although the “sense of quality” was.
