基于坐席区声衰变时间的专业足球场罩棚设计研究

Acoustic Design and Practice of Professional Football Stadium

2023年亚洲杯足球赛的举办促进了我国专业足球场的建设。国际足球联合会2011年实施的《Football Stadiums:Technical Recommendations and Requirements》中提出,为保护观众远离降雨和眩光,雨棚应覆盖全部观众,同时对坐席区的语言清晰度提出要求。以北京工人体育场重建项目为例,罩棚已覆盖坐席区,但是草坪区上方无屋面,罩棚在坐席区形成半封闭空间。文章从降低坐席区声衰变时间、提高语言清晰度的角度出发,采用艾润公式计算和计算机模拟的方法,对工人体育场的观众席和草坪区的声环境进行预测,并与验收测试数据进行对比。通过探索降低坐席区声衰变时间的设计方法,提高专业足球场罩棚声学设计的科学性。

The hosting of the Asian Cup in 2023 has promoted the construction of professional football fields in China.In the Football Stadiums:Technical Recommendations and Requirements implemented by the International Football Federation in 2011,it is proposed that in order to protect the audience from rain and glare,the canopy should cover all the audience,and at the same time,the language clarity of the seating area is required.Taking the reconstruction project of Beijing Workers Stadium as an example,the awning has completely covered the seating area,but there is no roof above the lawn area,and the awning forms a semi-closed space in the seating area.From the point of view of reducing the sound decay time in the seating area and improving the language clarity,this paper predicts the sound environment of the auditorium and lawn area of the workers' stadium by using the method of Airun formula calculation and computer simulation,and compares it with the acceptance test data.By exploring the design method of reducing the sound decay time in the seating area,the scientific acoustic design of the professional football stadium canopy is improved.
