回复: 自制扩散板 特美!

我也用公式算了一算,同样的尺寸,数据上好像有点差异,供楼主参考,63英寸高,well width2.86英寸 最深为15.75英寸,
影响的频段从214Hz-3146Hz,只能用英寸计算,麻烦转换一下,以下为详细尺寸,
See Program Help Files for interpretation

Well Number 0   WellDepth = 0 inches  
Proportionality Factor = 0
Well Number 1   WellDepth = .875 inches  
Proportionality Factor = 1
Well Number 2   WellDepth = 3.5 inches  
Proportionality Factor = 4
Well Number 3   WellDepth = 7.875 inches  
Proportionality Factor = 9
Well Number 4   WellDepth = 14 inches  
Proportionality Factor = 16
Well Number 5   WellDepth = 1.75 inches  
Proportionality Factor = 2
Well Number 6   WellDepth = 11.375 inches  
Proportionality Factor = 13
Well Number 7   WellDepth = 2.625 inches  
Proportionality Factor = 3
Well Number 8   WellDepth = 15.75 inches  
Proportionality Factor = 18
Well Number 9   WellDepth = 10.5 inches  
Proportionality Factor = 12
Well Number 10   WellDepth = 7 inches  
Proportionality Factor = 8
Well Number 11   WellDepth = 5.25 inches  
Proportionality Factor = 6
Well Number 12   WellDepth = 5.25 inches  
Proportionality Factor = 6
Well Number 13   WellDepth = 7 inches  
Proportionality Factor = 8

这样就放心了!我这大方案是俩名高人共同确定的,一位是在清华学的声学,现在吃的这碗饭,理论知识过硬,另一位是西安高烧老柴(石头音响店老板),其实战经验丰富,所以听音室的最终结果应该不会偏差太多!
我的大方案是:前面间隔那三块扩散板,左右俩侧是"间隔"的"微孔板"内填吸音绵,沙发俩侧是碟柜,后面是"大书架",顶上是"大小不等"的"间隔"的方框内10CM厚吸音绵外蒙装饰灰布........



个人看法,
按LZ描述的,这属前硬中吸后扩散类型,并在此基础上作些修改,
左右俩侧是"间隔"的"微孔板"内填吸音绵,建议在许可的情况下,适当增加离墙的距离,
希望LZ能获得所期望的声音,

希望这些意见能帮到你!
