1.楼梯后的部分会有低频共振,而且玻璃门会反射直达声.能否在楼梯那里加一道门,这样门后的部分相当于一个声闸,这样可以更有效的隔声.
2.侧墙的话,建议你在最里层添加吸音材料,比如阿土牌黑心棉当然,如 ...
1，门估计是加不成了。要加也是又一个大玻璃门，好像没有意义。不过阿土老兄的屏风倒是很值得copy一下。。。。
2. 侧墙是打算这么做。我这里还有很多波峰造型的黑海绵。塞在墙里的话，跟岩棉比哪种效果好一点呢？当然前提是墙面穿孔的情况下。
或者侧墙只用高密度（无穿孔）的石膏板做造型，里面填充岩棉？
3. 工作台上方的吊顶，现在的设计是木制框架，内放7厘米厚的微孔吸声泡沫，外包沙发布。

对了,白勺兄,还有一问题,你的扩散体是几踏步的?就是有多少格子? 高度是多少?这些决定扩散体的中心频率,要根据这些计算低频的吸收
扩散体还是准备用RPG的SKYLINE，这东东号称采用了某种专利算法。原文如下。
Interfering reflections can be controlled by absorption or diffusion. In small rooms, it is often desirable to control interfering reflections and provide an ambient sound field using diffusion instead of absorption. When the room’s surfaces are relatively close to the listener, a very efficient diffusing surface is needed. To solve this problem, RPG® patented the Skyline®. It is the industry’s first — and most efficient — omnidirectional primitive root number theory two dimensional diffusor. The Skyline® scatters incident sound uniformly so that the acoustic glare in all directions is minimized.
Problem
Small rooms like Project Studios need a very efficient surface to diffuse interfering rear wall reflections and provide a diffuse sound field.
Solution
To solve this problem, RPG® utilized advanced primitive root number theory to design the most powerful and aesthetic two dimensional omnidirectional diffusing surface in the acoustical industry.
Diffusion
Absorption
The solid expanded polystyrene core of the Skyline® provides useful low frequency absorption.
