| Summary: | 碩士 === 國立雲林科技大學 === 創意生活設計系 === 106 === The design of inclined roof is apply on many different kinds of building now which including school building. We cannot deny the inclined roof has article value, and it can not only increase the flexible application of space but also decrease the possibility of leaking on the roof. However, when the inclined roof is used on the type of classroom, the bigger space makes the reverberation time longer. It causes the voice unclear that makes the students decrease on the ability of listening to the class, and then impact on their learning. Therefore, this research wants to figure out the acoustical performance on inclined roof now. We take the classrooms of inclined roof in Yunlin county’s elementary schools as research subjects, and that of not inclined roof as a control group to measure and discuss the acoustical performance in the space. We hope to reach the goals below:
1. Understand the situation of indoor acoustical performance in the classroom of inclined roof.
2. Understand the indoor acoustical quantity differences between the classrooms of inclined roof and not inclined roof.
3. Provide the design references and suggestions about future classrooms.
The research data shows that inclined roof classrooms are not good on the assessment indexes of acoustical performance because of the big space.Only background noise has good performance and below the recommended value of this study. The data information of acoustical performance comparison between inclined roof and flat roof shows that when the inclined roof classroom’s average space volume is bigger then the flat roof classroom, the inclined roof classroom performs worse then the flat roof classroom on these five assessment indexes of acoustical performance, Background Noise, Reverberation Time, C50, STI and RASTI.
