武汉月亮湾城市阳台室外剧场声学优化与设计

Acoustic Optimization and Design of the Outdoor Theater in Wuhan Moon Bay Urban Balcony

武汉月亮湾城市阳台项目由英国扎哈·哈迪德建筑事务所与中南建筑设计股份有限公司联合设计,是武汉长江主轴九大城市阳台之一。项目利用武汉江滩高低起伏的地形景观,创造不同的主题广场和多样的文化设施,户外椭圆形剧场是其中最具特色的公共活动设施之一。该文拟以室外剧场的声学优化与设计为例,从声反射和回声控制、混响设计、电声系统设计、噪声控制等方面出发,并结合地域性特点,对我国类似城市广场户外公共观演空间的声学设计方法进行探索。

The Wuhan Moon Bay urban balcony project was jointly designed by the British Zaha Hadid Architects and Zhongnan Architectural Design Co.,Ltd.It is one of the nine urban balconies on the main axis of the Yangtze River in Wuhan.The project uses the undulating topography of the Wuhan River Beach to create different theme squares and diverse cultural facilities.The outdoor oval theatre is one of the most distinctive public facilities.In this article we intend to take the acoustic optimization and design of the outdoor theater as an example,starting from the aspects of acoustic reflection and echo control,reverberation design,electro-acoustic system design,noise control,etc.,combining with regional characteristics,we explore the acoustic design method of the performance space,so as to provide a view of the outdoor public view of similar urban squares in our country.
