Acoustic enhancement systems have become popular in recent years and are broadly used in various kinds of facilities because of their acoustic naturalness and system stability. Today, demand for acoustic enhancement systems exists not only for multi-purpose halls but also for highly absorptive spaces, especially lecture halls and theaters. To investigate an effective enhancement system for highly absorptive spaces, we compared several enhancement methods that are commonly applied in a small auditorium. This paper summarizes the features and the acoustical characteristics of systems configured according to each of the considered enhancement methods in the small auditorium.
