长混响声场的语言扩声技术探讨

Sound Reinforcement Technology Discussion of Reverberation Sound Field with Long Time

有些大型场馆和厅堂,在设计时未充分考虑建筑声学设计,其建声条件很差。怎样做好这类场合的扩声是极富挑战性的。探讨了在建声混响时间很长的环境中做好扩声的主要对策,提出了语声"高清"的概念,并对基于"高清"要求下设计扬声器的要点作了小结。

Some large venues and halls in the design are not taken full account of architectural acoustics, architectural acoustics conditions are very long reverberation time. This article discusses the main countermeasures to make a good sound with long reverberation time and architectural acoustics condition, puts forward the ＂STIPA＂ concept, and makes a summa- ry focuses on design a loudspeaker based on ＂high articulation＂ request.
