摘要
介绍一种仅使用强吸收和强反射两类极端吸声构造进行听音室声学设计的理论和方法,并给出按照该方法进行设计的听音室实例,以及对该听音室的房间频率响应、混响时间实际测量的结果。实测数据显示了与解析计算结果有着较好的吻合度。在整个设计频段内混响时间特性曲线平直,混响时间实测值和设计值的偏差在63～4kHz的6个倍频程内为0.02s。
A method based on anechoic-reverberant-type theory is proposed and an example case is given. The frequency response and the reverberation time of the room are measured. The results matches well with the theoratic caculation. A fiat reverberation time characteristic is also obtained in a six octives range from 63 Hz to 4 kHz. The standard difference between measured and prediceted reverberation time is 0.02 s.
