Thinking on HVAC professional acoustic measures in China National Opera House
摘要：
中央歌劇院要求演出時采用純人聲發聲，觀眾廳聲學設計標準為NR20，高于國家相關規范數值。針對項目設計階段聲學措施對暖通空調設計產生的主要影響進行了闡述分析，包括池座、樓座空調機房設置，樂池空調系統設置，管道風速確定及消聲器設置等。
關鍵詞：聲學標準；暖通空調設計；人聲劇場；設計優化；聲學測試
Abstract：
The China National Opera House requires pure human voice during performances, and the acoustic design standard of the auditorium is NR20, which is higher than the value of the relevant national specifications. This paper describes and analyses the main impacts of acoustic measures on the HVAC design in the project design stage，including the setting of pool and building air conditioning rooms, the setting of orchestra pool air conditioning system, the determination of duct wind speed and the setting of mufflers.
