世界顶级音乐学院建筑隔声构造施工技术体系研究

Research on Construction Technology System of Sound Insulation Structure of World Top Conservatory of Music

天津茱莉亚音乐学院是世界最顶尖级的专业音乐学院,是美国茱莉亚学院的第一所海外分院。该院包括音乐厅、演奏厅、排演厅和黑盒剧场四个主要部分。开学后,每年240名硕士生在天津享受来自美国茱莉亚音乐学院的专业教育。世界级音乐大师会来此教学和演奏,部分演奏会向普通民众开放。由于长期专业的训练,音乐大师的耳朵变得极为灵敏,越是安静的环境,越能让音乐大师捕捉表演中最细微的声音。噪声过大会影响到音乐家的心情,干扰到演奏效果。因此,一座世界顶级的音乐建筑,隔声设计合理,满足声学要求是第一位的。美国茱莉亚学院的声学是25分贝,国家大剧院的声学是25分贝,天津茱莉亚音乐学院声学要求是20分贝~([1]),比两个最顶级的音乐用建筑的声学要求还低5分贝,设计和建造的难度更大。

Tianjin Juilliard Conservatory of Music is the world's top professional conservatory of music and the first overseas branch of Juilliard Conservatory of America.Tianjin Julia Conservatory of Music consists of four main parts:concert hall,performance hall,rehearsal hall and black box theater.Since the beginning of the semester,240 postgraduates enjoy professional education from Juilliard Conservatory of Music in Tianjin every year.World class music masters will come here to teach and perform,and some of them will be open to the general public.Because of long-term professional training,music masters make their ears extremely sensitive.The quieter the environment,the more guarantee that the music master can capture the most subtle sound in the performance.Excessive noise will affect the mood of musicians and interfere with the performance effect.Therefore,a world-class music building,sound insulation design is reasonable,to meet the acoustic requirements is the first.The acoustics of Juilliard College in the United States is 25 dB,that of the National Grand Theater is 25 dB,and that of Tianjin Juilliard Conservatory of Music is 20 dB,which is 5 dB lower than that of the two top music buildings,making the design and construction even more difficult.
