杭州剧院原设计曾考虑加设舞台反射板,以便在举行音乐会时获得更好的音质,但当时由于经济条件未能实现。1986年7月正式决定加设,并立即进行设计,设计上考虑采用分离式反射板。该反射板8月中旬首次由日本静冈交响乐团使用(图1)。演员及听众对此反射板效果反映良好。现将其设计、使用及测试情况介绍如下。 The original design of the Hangzhou Theater had considered the installation of stage reflectors to obtain better sound quality at the time of the concert, but at that time due to the failure of economic conditions. In July 1986, an official decision was made to set up and design immediately. The use of separate reflectors was considered in the design. The reflector was first used by the Shizuoka Symphony Orchestra in mid-August (Figure 1). Actors and listeners reflect this reflection board effect well. Its design, use and testing are described below.
