摘　　要：传统声屏障外观在降噪改造中往往显得突兀而单调,难以融入周边环境,有必要将建筑形式和景观需求相结合对声屏障形式进行一定设计。以广州市一高速公路旁某中小学为例,对校园室内外声环境现状进行实测分析,运用SoundPLAN软件对校园声环境现状进行模拟。在满足降噪效果的基础上,结合建筑立面形式和景观要求设计了3种立面声屏障,并利用Odeon Combined软件对不同设计形式的屏障进行模拟,探究其对教室内声环境的改善效果。研究表明,在门窗全开的情况下,不同形式的屏障降噪效果在5~9 dB(A)之间,对教室内语言传输指数(Speech Transmission Index,STI)的提升效果在0.09~0.15之间,能较好地缓解教室内声环境现状。Traditional sound barriers are often visually obtrusive and monotonous in noise reduction renovations,which make them difficult to blend into the surrounding environment.Therefore,it is essential to integrate architectural forms and landscape requirements when designing sound barriers to achieve a certain aesthetic form.With a primary and secondary school near an express way in Guangzhou as an example,the indoor and outdoor sound environment status is measured and analyzed on-site.The SoundPLAN software is utilized to simulate the current sound environment.Three facade sound barriers are designed based on the requirements of noise reduction and building facade form,and their acoustic performance is evaluated using Odeon Combined software.Results show that the designed sound barriers can effectively alleviate the environmental sound in classrooms.When the door and windows all open,the noise reduction effects of different barriers are in the range of 5-9 dB(A),and the improvement effect of Speech Transmission Index(STI)is in the range of 0.09-0.15.
