The acoustic quality of a concert hall has frequently posed
a mysterious puzzle, namely, what physical aspects of the
sound field can produce superior sound for the listener. The
author has been probing for more than adecade into the
subjective qualities preferred for musical and speech
sounds. The result of his extensive investigations - the
discovery that four and only four independent parameters
contribute effectively to good acoustics - is summarized in
the present book. The capability of calculating acoustical
quality at any seat in a proposed concert hall is a unique
and quite useful aspect of Ando's design method. Alternative
architectural schemes can be compared based on the number of
seats which exceeds a previously accepted minimum standard
of acoustical quality.
