minime 寫: Raymond兄, Realtraps 的吸音data 有Mini, Mondotraps 等的靠牆 與 角落擺法的數據比較,
例如這張:
非牆角擺設恐怕在低頻(250Hz以下)的表現會打相當大的折扣.
或許可以增加一組 Realtraps in corner 的測量?

minime 兄
請注意此文主題 --> 再試 RealTraps 用作牆角 Bass Trap 低頻陷阱 (即主要試 RealTraps in Corner)
你是否忘記了? 是否短暫失憶?
MondoTraps x 2 + BareTraps x 4 + MiniTraps x 2 [In Corner]

Raymond兄 可能是我短暫失憶, 但怎麼沒看到您獨立測試All Realtraps in corners (including baretraps)
您之前的討論串發表時應該還沒納入baretrap吧. 我的意思是想看到在此環境的同場比較測量,
(+mondotraps in front corners )最好是有overlap plots 可看.
另外您的stacked traps in corner 似乎與Realtraps 建議的設置原則有違背喔.
這類設計的bass trap 前後堆疊使用的效率較低喔.
還有在on wall(側方放置)的位置後方有窗簾, 可以請問後方是實牆嗎?
Thanks in advance.

因為我窮,自知能力有限,無錢買有獨立影音室的豪華大宅
故只能盡用有限空間,在豆潤大小約有實用面積 240 呎客廳內玩 HiFi 及 AV
可幸老細極為體諒,承諾讓出整個客廳,供我堆放一件二件大大小小的影音器材
更重要的是,從不投訴及不過問我買入任何器材,只要維持整潔便可
所以我亦心感滿足,與老細相敬如賓,樂也容容,亦不愁衣食
在麻雀雖小,但五臟全的小康之家中生活,自問也算是有一個美好家庭啊!
怎會家不成家呢?

The BareTraps are brand new that I just purchased in late December 2009.
I just received the BareTraps and did a quick comparison tests together with MondoTraps and MiniTraps before passing them back to Eddie hing.
Please note for Effective Bass Trap, the capability is directly proportion to the size and thickness of it.
Hence, in order to handle the extremely low bass problem such as 26Hz in may case, I need to use a very thick bass trap. Therefore, I add the available Mondo & Bare Traps together to simulate a bass traps.
Please provide me the link that highlighting the in-effectiveness of the RealTraps when place one behind another.
Please note the RealTraps are not magic stuff, it is just making up by normal sound absorption materials such as Rock Wool, etc. Hence, the thicker the materials, the higher absorption capability to absorb the low frequency energy.
On the left side wall is solid concrete wall while on the right side wall is a bay windows that I have indicated in the drawings.
From numerous tests that I performed on RealTraps, the consistent results are obtained --> not effective to enhance the bass frequencies in my home environment.
However, I use it as a absorption panel for 1st reflection point so as to balance the sound reflection of the left side (concrete wall) and right side (bay window).
As I clearly mentioned in my last post, I am not able and will not perform any further test on RealTraps as I need to return them to Eddie and I have satisfied with the findings.

MiniTraps and MondoTraps are made from double-density rigid fiberglass that is mechanically stable and won't sag, deform, crumble, or develop lumps over time as can lesser products made from foam or mineral fiber. We then bond a limp-mass membrane behind the fabric, which doubles the absorption at bass frequencies when compared to plain panels the same thickness. The fabric we use is custom made for us with a density and weight specific for acoustic panels, yet is thick enough to ensure that no fiberglass particles can escape into the air
是屬於panel trap(membrane trap), 是pressure type 非 velocity type bass trap.
