我是说按你那张大图。
按你的顶贴的小图,就是音响放左边,人坐右边。

其实小图跟大图的方向一样,缩小版版只是做了点修改。

这一看,“卖葛”!!!重起兄的房间连一个窗口都没有!!!是否需要做点改动?

不好意思提我那房子,帖子上没有人拍砖很遗憾!——其实那是一堆破烂,真的,就是我在我所住的城市里面到拆建区拣回来的废旧材料垒起来的。况且我的要求并不高,在所费不多的情况下作的尝试。
真希望有一天楼上诸位亲临现场嬉笑怒骂一番!!!
可现在,我想请madog兄先在网上看一看。
madog兄:承蒙不弃,请进http://www.hifi168.com/bbs/article.asp?titleid=39496&ntypeid=10




Quite a nice room. Thanks.

The biggest challenge for audiophile is to spend least of the money to obtain the best result. Yes, at least for some guys do not have so mushc  
resources to spend.

Looking back to one of the guy's post, one of the article from Taiwan
saying how the room was designed and had it made.

That article is a typical audiophile's thinking as I've found they did not
consider the room as a whole but trying very hard to show us he is an
audiophile. This also true to some DIYers trying to put all the best (market
says the best) components in their equipment but at the end, sounds
terrible.

Spare parts is like a painting brush but the picture is from the artist or the
painter.

低频过量:
音箱一般需离长更远,音箱内折角度加大

惨了,原来madog的中文水平跟我的英文水平有得挥!
谁说了:“The standing wave is coming from the CD recording ”  


madog兄也是好意提醒。

是啊!的确有文化差异!

音箱采用331摆法,后墙加吸音布,前面也加吸音布,如果是窗子加厚窗帘,地毯满铺,侧强加扩散帘,在适当的的摆位,驻波很容易就没了.一定要勤动手.

You must built few bass absorber or bass trap to solve the problem as your
room has a lots of STANDING WAVE!!!

There are 10 standing waves in axial mode below 200Hz and
4 standing waves at tangential mode.

Axial mode : 22.8, 41, 45.6, 82, 68.5, 123, 91, 164, 114,  136,
Tangential mode : 46.8, 93.7, 140.6, 187.54,

There will be more if you have the ceiling height.

Remember, only bass trap would do the job

Good  luck, buddy

谢谢buddy Madog.
哇,你的回应好科学!
接近200Hz的驻波最是困扰---琴姐的独白
Any easy (and inexpensive) way to make a bass trap and where to put them?



The strongest peak of any standing wave is in every corners of the room.
You may put the bass trap by corners and is the most effective way.

Personally I would prefer the bass trap made as a wardrobe attached to the corner wall. These traps can be made rectangular of triangle shape depanding on the locations and designs. They are simple made from chip
board of MDF with fiber glass filled. However, it must be carefully
calculated for the target frequency and the board used also need some
datas such as the mass of the board per square feet of square meter, so
and so............

Cheers

蔡蔡的歌声中没有200Hz的东东吧?我想应该是中音。

好专业的结构图,应该用visio画的?


谈不上专业吧?先不说真正的专业是CAD,就算VISIO的专业也不是这个样子的。
