The purpose of this study was to investigate the acoustical characteristics in each seat of a concert hall. Subjective evaluations were made with measurements of objective acoustical parameters. The experimental methods were questionnaire survey, field measurements, analyses of ACF/IACF. The scale of overall impression was highly correlated with 'Reverberance', 'Envelopment', 'Intimacy', 'EDT (Early Decay Time)', 'ITDG (Initial Time Delay Gap)', 'SPL (Sound Pressure Level)' and 'τ_(IACC)'. These acoustical parameters were considered as the most important in deciding the overall impression by audience for the acoustics of concert halls.
