基於建築永續發展的概念與既有建築再利用的理念以及台灣藝文表演空間需求日益 |
| 增 |
|
加之下,有保存與再利用的必要;本研究因此以台灣既有集會型建築之音響環境為主題 |
| 。 |
|
在音響性能的歷史發展方面,再行論述台灣各時期集會型建築音響性能發展情況並 |

|
標的內容內容方面,包括室內音響性能、室內背景噪音、電氣音響系統等三部份;在音 |
| 響 |
| 性能方面以物理指標(RDT、G、C、BR(RT))做為評估指標,室內背景噪音則是
以噪音 |

|
評估電氣音響性能。對兩個不同時代的既有集會型建築個案師大禮堂(1929年)、台大鹿 |
| 鳴堂(1967年)的進行量測、評估。並獲致成果: |
| ˙音響性能發展方面: |
| 1. 早期台灣的發展較西方先進國家有較大的落差, |
| 2. 由於構造的因素,致使侵入噪音問題嚴重, |
|
3.戰後個案的容積與座席之比,較日治時期小,且餘響(RT)較短,對日後更新會有所 |
| 限 |
| 制。 |
| ˙音響係評估方面: |
| 1.依評估結果廳堂使用機能,應有所限制,以符合評估性能要求, |
| 2.潛在音響問題的不易評估,需深入探討, |
| 3.電器音響系統的完整性稍嫌不足,但性能尚合於使用需求。 |
|
本研究的整體研究成果,將累積集會型建築音響環境的本土資料,建立集會型建築 |

| [摘要] |
| Reuse and renewal of existing
public gradually become necessary because |
| of |
| economical and preservation.
The research is conducted to evaluate |
| acoustical environments for
existing auditoria in this research. |
| The research contents include
reviewing evaluation criteria, acquiring |
| architectural data via field
investigation or documentation review, and |
| fielding out the acoustical
characteristics of the existing auditoria in |
| Taiwan. Field trips will be
taken together and data can be shared among the |
| integrated research team .The
acoustical environments include the room |
| acoustical qualities, the
background noise levels, and the performances of |
| the |
| speaker system. |
| The evaluation of acoustic
properties includes indoor acoustic |
| properties, |
| of indoor background and the
system of electronic acoustics, which, |
| respectively, base their
assessment according to the arrand the index of |
| questionnaires. The evaluation
index of acoustic properties lies in |
| physical |
| index (ie: EDT、 G、C、BR(RT));
the noiseof indoor background lies in |
| questionnaires to access the
integrity of the quality of equipment, which |
| bases its evaluation of
electronic. |
| This research accumulates
documentation and acoustical data for local |
| architectures.The results can
be used in architecture practice in renewing |
| existing auditoria as well as
in new auditoria design regarding aging |
| consideration. |
