Abstract: An acoustical performance evaluation method includes a reference sound pressure decision step and a deviation calculation step. In the reference sound pressure decision step, frequency response of sound pressure level, obtained by considering only an influence of a first factor of a plurality of factors causing a deterioration in frequency response of sound pressure level of a loudspeaker to be evaluated, are decided as a reference sound pressure. The reference sound pressure is frequency response of sound pressure level of the loudspeaker in the anechoic chamber calculated through a simulation or measured through a measurement experiment. In the deviation calculation step, a deviation between the reference sound pressure and a target sound pressure is calculated as an evaluation index of acoustical performance. The target sound pressure is frequency response of sound pressure level of the loudspeaker in the anechoic chamber calculated through a simulation or measured through a measurement experiment.
