摘要
厅堂中的耦合空间会使主厅的声衰变曲线呈现前后不同斜率的双折形。这样可兼顾到音乐厅中清晰而又有丰满混响感的音质要求。改变耦合开口的大小又可控制后期衰变曲线的斜率,从而达到可变混响音质的效果。评述了这方面的进展,并探讨了厅堂音质设计中其它形式耦合空间。
A double-sloped sound decay in a concert hall resulted from a coupled space will reconcile the often-competing qualities of clarity and reverberation. Controlling the aperture size will also provide a sound field that is variable, longer and distinct. The author presents an overview on this subject and also other cases in hall acoustics.
