Acoustic Scale Model Study On Stage Enclosure Using

Stage is the core of the drama performance buildings, good stage acoustics effect to the performers and the audience is very important. At present the world on special concert hall is less, most of the drama performance buildings adopt multi-function hall, as well as operas, ballet, etc., can also be held a concert For making effect is similar to the special music hall in the theatre space form and acoustic conditions, often on the stage set up mobile, easy loading and unloading stage acoustic reflector. In hall acoustic reflector installation stage, can strengthen the interaction between the musicians heard, the balance of play acoustic fusion,.This paper mainly through the reduced scale model experiment, research of the acoustic effect of stage sound reflection and the ideal structural form.In summarizing predecessors’ research achievements about stage acoustic reflector, based on the design made a1:10scale model theatre and stage sound reflection cover, and acoustic model test in order to test different stage acoustic reflector structure, stage and the audience hall of quality indicators, including ST1, C80, T60, EDT, etc. And carries on the analysis discussion, the result of the test through the experiment preliminarily concluded that if the ST1(stage) the demand is higher, can use7meters and10meters height, Angle of20degrees better; If C80(definition) the demand is higher, can use Angle of0degree of roof or ceiling height of10meters; If T60(reverberation time) the demand is higher, can use10degrees roof Angle, height of7m to10m better; If EDT (early decay time) the demand is higher, can use7meters and10meters high,10degrees inclination or use10meters height, Angle of0degree and20degree better;Based on experiment and analysis, the acoustic reflector is stage acoustics requirements and design are also proposed.
