碩士 === 國立臺灣科技大學 === 建築系 === 102 === A vineyard hall design scheme with roughly 1/4 surrounding seats is proposed and evaluated using computer modeling as a follow-up study of previous development where the audience area and hall volume are 1440 m2 and 22000 m3, respectively. The simulation is verified using a 1/20 scale model where the volume and material is fine tuned through a series of measurements. The effect of the farthest row of seats was tested using an omni-directional source while the effect of the nearby walls in front of the stage was tested using a directional, voice source. The results generally show reasonable strength and reverberation for a 34-m wide vineyard hall by appropriately introducing side, frontal, and corner terraces. Lateral energy fraction is superior to published average performance of large size concert halls, especially when considering the excessive width of the model hall. Near 3 dB compensation of high-frequency strength from the directional source could be derived by introducing the nearby terrace walls in front of the stage. The strength from individual seat of scale modeling is less dispersed then the data from the computer modeling although the average value from the former is weaker. The findings demonstrate the feasibility of designing a vineyard hall to fulfill well-accepted acoustical design objectives. It can also be used as a reference for the innovation process for an actual design project. Design or experimental factors such as terrace wall aiming, stage overhead reflectors, performer chairs on stage can be further optimized or studied.
