房間不對稱，走道在CD 櫃的正對面，相信這是為甚麼把 MondoTraps 放在 CD 櫃前面效果最大。其實測量時我無意中發覺打開 CD 櫃門帶來 3db 的改善。先放一個MondoTraps，再加一個，終於解決 80Hz ~ 100Hz 的問題，但也帶來另一個問題...必須先想好要聽那些 CDs, 一次取出:D:P引用:

這也是因為壓低間接音強度，平整的門板反射遠比雜亂擺放的CD反射強的多引用:

各位老大，在基礎裝修時最應該注意的是什麽啊？是先注意擴散、反射、還是吸音啊！糾結得很！
我也是小房間.有聲音表現不佳的問題. 朋友的介紹我去Ｙ拍買了四片全向擴散板.照著賣方提出的位置擺放說明.嘗試把喇吧向外移動. 會有明顯的改善了定位及音場的表現.引用:

現在也推薦給大大嘗試看看.

Acoustic Geometry Curve System room treatments
By Erick Lichte • Posted: Feb 10, 2012
http://www.stereophile.com/images/212curve.promo_.jpg
For a few weeks each year in the high summer of Minnesota, the corn sold from rickety roadside stands is so sweet and tender it is best eaten unadorned. For the wise and lucky nibbler willing to forgo condiments, the rewards of eating these naked kernels are the pure taste of Midwestern soil and sun transformed into a juicy, golden confection. I've begun to wonder if the yearly encounter with this magnificent and ephemeral sweet corn reminds Midwesterners of the joys of simplicity and plainness. Though my hypothesis is a stretch, it sure would explain a great deal about the Midwestern mentality. Perhaps Midwesterners subtly learn from this corn that if we get too fancy or try too hard, we can often screw up what nature has already made perfect. Conversely, we learn that no amount of fancy accoutrements will make a bad ear of bland, mealy corn come alive in the mouth. What I've learned from room acoustics, room treatments, and room corrections are very like the lessons I've learned from eating the sweet corn of summer. Like drenching in butter a starchy ear of corn, there's just no way you can make a bad room sound great. If your listening room's floor vibrates like a kettle drum, your walls are glass, and your ceiling only 6' high, all I can say is: Good luck. Every attempt I've heard to treat a fundamentally bad-sounding room with panels and equalization at best trades off one sonic problem for another. On the other hand, when a decent-sounding room is turned over to a company selling panels or corrective components, often the natural goodness of the room's sound is destroyed in a quixotic quest to even out the bass response or null every standing wave. Though such rooms might end up measuring better, they don't always sound better. Adding too many acoustic panels to an okay-sounding room is akin to ruining the perfect ear of corn with too much salt.
So it was with a sense of hope that I encountered Acoustic Geometry's new Curve System of room treatments. Unlike most products designed to treat rooms by absorbing sounds, the Curve System treats room acoustics predominantly through diffusion. I was intrigued by the approach, and as Acoustic Geometry products are made close to where I live, in Chaska, Minnesota, I thought it might be convenient and fun to see if I could get my room to sound a little better. I called John Calder of Acoustic Geometry, told him about my room's size and materials and what it's made of, and he sent a pallet of products to my door.

這面牆真不錯看比文化石好看多了.價格應該貴不少..

圖中兩側牆放的是RPG Abffusor嗎?
請教效果如何?
感謝~~~
Det är inte lätt att få tiden att räcka till så det får bli lite av en sömnlös natt.
Vad gör man inte för en stackars hobbykollega som inte har plats i agendan för
att besöka olika mässor http://www.euphonia-audioforum.se/fo...smile_wink.gif http://www.euphonia-audioforum.se/fo...icon_smile.gif .
Svanå hade ju mer eller mindre möblerat hela Drottningholmssalen där Audio Concept
ställde ut delar av sitt MBL-sortiment och i en liten hörna kunde man beskåda dessa...

Den vita varianten är färdig för tak/väggmontering och möjligheten till inbyggd belysning finns också.
Kanske något att hänga ovanför köksbordet utifall att diskussionerna skulle ränna iväg volymmässigt http://www.euphonia-audioforum.se/fo...efault/dry.gif ... http://www.euphonia-audioforum.se/fo..._smile_big.gif
Pappvingen för "vänner av Ikea" fanns också för beskådning.

小葉站長....不是英文不會翻譯
希望能有所說明..功德無量
在網路上找到一份文件!!
噪音原理防制材料
還是環保署發的資料,不錯用!!:)
很詳細實用的資料,謝謝分享!

音響室不是一些數字就解決的，很多內裡外在~~~~`
可以請教KEE兄的喇叭距離背牆的距離嗎?(從單體到背牆)
50Hz凹陷的狀況和我家相當類似!
請教#224中長方形像屏風的東東是什呢？
落地窗前的兩片是可移動的擴散板嗎?什麼牌子?那家代理?引用:

furutech之前有類似的產品，可問看看~~~~~~~~~~

這個應該是souns faber出的擴散板,之前有在新竹的音響店看過引用:

那白色的部分其實是有點像瓦楞紙一樣的波浪狀,
其實souns faber還出過家具沙發,搭配他們家EA1

大家好，請教各位大大，一個８．８尺寬 ３５尺長 １０尺高的空間，要如何來適當的空間處理？
其實不分房間大小, 8成以上處理的方法應該都不脫, 六個牆面的第一反射點吸音, 四個角落放低頻陷阱引用:
作者: 五谷
剩下的就是選用的產品 (或者自己設計的東西) 效能如何了.....吸音的頻率範圍盡可能要寬,
也就是說, 產品要夠厚,
看坐位背後離牆多遠, 若有1.5公尺以上則可以考慮改用擴散
8.8尺當成寬的話.為2.67米(幾乎同我空間).是有點窄.
若當成置長邊擺設.又很不近人性.
高很接近.長比我為1.5倍.
偏長形空間.
消散狀況(RTA)會比較麻煩一點.
左右牆第一反射點會是最先一波到..要加強處理.
其他面..?
建議依實際系統發聲狀況再研判了..
謝謝chsiang,
因無儀器可來測試頻率段，所以就以樂器聲來簡單的描述．腳踏鼓聲還算可以過得去，雖然膀腫了一點點，但還可以接受，人聲都算可以接受，差了一點對焦（喇叭擺位應該可以修正），高頻方面也算不錯．就是在鼓棍敲在鼓皮那段音頻就嚴重失真了，沒有鼓皮聲的感覺，聽到得只是一團模糊聲而已．這是那一段頻率的問題？
謝謝葉sir.
有什麽比較實際易處理的方法嗎？
低頻摟, 可能200Hz以下開始就有問題了引用:
作者: 五谷
問題是更深沉的大鼓播放還可以接受，線條＇比例＇結實度都可以，為何在小鼓卻出現模糊了？
