Preference tests of seven European concert halls using musical motifs recorded through a dummy head were performed. Test signals were reproduced binaurally. Eighty‐eight students served as subjects. The results show that (1) there was no significant difference between preference scores for these halls when averaged over all subjects, and (2) subjects could be divided into several groups with respect to preference. In conclusion, even though each subject was free to prefer hall A to hall B, the acoustical quality of a certain hall could not be solely evaluated using the preference score.
