一個理想的多功能廳堂必須具備可調機制來因應不同演出需求,使室內聲場品質具有專門音樂廳之水準。可調機制首要目標在控制餘響時間。可調機制大部分採用調整材質的邊界表面吸音力為主要手法,但其對於低頻調幅控制性不如耦合空間有效。因此再加上舞台耦合容積,來控制低頻的調幅。
本研究針對一個403席的小型多功能表演廳,利用縮尺模型與現場量測為工具,兩者比對參照。綜合性討論各種可變機制對耦合效應的影響,包含舞台音樂罩、反射版、吸音幕等餘響可變機制,來產生雙斜衰減曲線,達到餘響感與清晰度共存的良好室內聲場。
以現階段研究結果顯示,舞台耦合容積增加,明顯提高觀眾席在低頻的早期衰減時間。利用第一道布幕為耦合面,可提供一半的T30調幅。經由利用縮尺模型與現場量測兩方法所得的實驗數據,顯示兩種量測方法在T30跟EDT,方法彼此之間有良好的相關性。表示縮尺模型可以準確的反映實際廳堂聲場餘響時間。
An ideal multi-hall would have adjustable mechanism for different performance demand, make indoor acoustic field quality have level of the special music hall. Primary goal of the adjustable mechanism is controlling reverberantion time. Adjustable mechanism most to adopt border surface to adjust material suck sound strength the main tactics, but it is not so effective as the coupling space in control to amplitude modulation of low frequency. So the combination with the volume of stage coupling controls the amplitude modulation of low frequency.
Research this perform the drawing room to one 403 small-scale large menus of seat, utilizing the model and scene amount of the reduced scale to examine for the tool, the two consult than correctly. Comprehensive to discuss various kinds of variable mechanism impact on coupling effect, include stage music put on, reflect edition, suck sound scene my loud variable mechanism, is it produce pair oblique to decay curve, reach I loud sense and good indoor acoustic field that definition coexist to come.
Show with the result of study of the present stage, the volume of stage coupling increases, obviously improve the auditorium in the early decay time of low frequency. It can offer half the T30 amplitude modulation the coupling to utilize the first cloth curtain. Viautilizing the model and scene amount of reduced scale to examine the experimental datas of two method incomes, show two kinds of quantity examine methods in T30 and EDT, the method has good dependence each other. Show reduced scale model can accurate reflection actual hall acoustic field over loud time.
