First, one music motif is chosen from 16 motifs (string concert music, a
violin, a flute, trumpet, etc.). Next, from this motif, the dozens of sound with
different sound parameter is made by using DSP. A subject listens pairs of two
different sounds among them in an order, and judges which was desirable. This
judgment is immediately transmitted to the control PC via the switch installed
in the test room. A test is ended in about 15 minutes. Then the individual
optimal sound field is determined. The optimal seat in sound quality is searched
in the hall from this test result. With the degree of aptitude, all seats in the
hall are classified in three stages, and displayed with different colors.
