室内声学设计中早期反射声的作用及控制

Subjective Effect and Control of Early Reflections in Room Acoustical Design

简述了哈斯效应和梳状滤波效应及其对主观听音的影响,然后对厅堂和听音室早期反射声的作用及控制进行说明,重点说明了厅堂最佳侧向反射声和听音室或控制室最佳初始延时,最后介绍了反射面有效工作频率下限的计算公式。

After introducing the Hass effect, the comb filtering effect and its subjective influence on listening, the subjective effect and the control of early reflections in concert hall and listening room design are introduced. The optimum lateral reflections and the optimum initial delay time are mainly explained. The formula for calculating low cut-off frequency of reflectors is also presented.
