"Architectural Acoustics" is a specialized book that addresses the theory and practice of acoustics in architectural spaces, particularly in concert and multipurpose halls. The author, Yoichi Ando, guides readers from fundamental theories to detailed design studies and offers a remarkable seating selection system for analyzing new and existing halls. The book also includes a diagnostic system for checking physical properties and calculating psychological attributes at each seat after a hall has been built. Additionally, a theory of subjective preferences is presented, based on a model of the auditory cognitive system in the brain. Readers can trace the temporal and spatial values associated with the left and right hemispheres of the brain when listening to music and speech in a space. These insights are significant for architects, musicians, and acoustic engineers to determine optimal performance venues and seating arrangements and to optimize hall design.
