現為台北市二級古蹟的中山堂，因為內部設施老舊及古蹟再利用的需求，正重新整建中， |
|
而其整建後的目標係提升中山堂的使用功能，使其內部之中正廳成為一個可以提供音樂、 |
| 戲劇、演講….等多功能藝文活動演出的場所。 |
|
本研究係以電腦模擬來輔助中正廳聲響環境的設計，分別以客觀指標及實際聲音的模擬來 |
|
輔助設計，並在中正廳完工後對其聲響環境作量測，以確認中正廳於整建完工後之聲響環 |
| 境能達到預定目標。 |
|
以電腦計算客觀指標來輔助廳堂設計，可以發現設計上的缺失，經多次的修改，使設計能 |
|
達到預定目標。而模擬實際聲音則可以經由樂評家及音樂家的實際感受，對初步設計提出 |
|
其主觀之評估，經反覆與樂評家及音樂家溝通，並與客觀指標配合，對設計做多次修改， |
| 以保證實際完工後的廳堂能讓聽眾滿意。 |
| 中正廳完工後的測試結果發現，500、1000
Hz之餘響時間都在1.4秒以上，音壓分佈除一樓 |
| 前排中央位置外，其他位置均在平均音壓的 ±5
dB之間，而明晰度除二樓前排中央位置外 |
| ，其他位置均在 + 4 ~ - 4
dB之間；由上述結果來看，中正廳整建後的聲響環境已達到設 |
|
計時所訂定的目標。對於小部分音質未達到預定目標的區域，本研究也以電腦模擬去分析 |
| 瞭解，並提出改善的方案。 |

| As a national second grade relic
in Taipei city, the Chungshan Hall is |
| currently in the process of
renovation due to its outdated equipments and the |
| need of reutilization for
multiple purposes. The goal of this renovation is |
| to increase its functions so
that versatile cultural activities such as music, |
| opera, conference, and lecture
programs can be accommodated. |
| In this study computer
simulation, including the calculation of objective |
| indices and auralization
(synthesis of real sound), was used to aid the design |
| of Chungcheng Auditorium. Field
testing was performed after most of the |
| interior section of the
Auditorium was finished. |
| Through the calculation of
objective indices by computer, we were able to |
| discover deficiencies in early
design stage, and then implement repeated |
| modifications to ensure that the
preset goal be achieved. The auralization, |
| on the other hand, can help
music critics and orchestral conductors offer |
| useful subjective evaluation. A
successful integration of both subjective and |
| objective evaluations can thus
offer a better design to satisfy the perspective |
| audience. |
| The testing result of the
Chungcheng Auditorium showed that the reverberation |
| time at 500 and 1000 Hz were
above 1.4 seconds. The maximum difference of |
| sound pressure level was below
10 dB. For the clarity (C80), all but a few |
| central front seats on the
balcony fell in the range of 4 dB and –4 dB. The |
| measured objective criteria thus
revealed that the majority of the acoustical |
| environment of the Auditorium
has reached its goal. For the small portions |
| where acoustical qualities were
not satisfied, recommendations were also given |
| for their improvements. |
