Optimized design for an anechoic-reverberant-type listening room

A method based on the combination of finite element method and Anechoic-Reverberant-Type theory is proposed for obtaining an expected listening room with a flat reverberant characteristic and a suitable shape.The industry practice was carried out and the measurement was taken.The predicted results matched well with the measured data.A 6 dB reduction of standard difference of frequency response was achieved after the room was optimized.A flat reverberation time characteristic was also obtained in the trail room.
