| [#32] 天花版吸音物料及安裝的意見 Seldom visited here again. ... That's very interesting. 16 years passed. I have moved to another house. Renewed all gears. Yes, the problem is solved. My knowledge of room acoustics improved considerably. But haven't investigated further more on room acoustics knowledge since 2016/7/8. Reasons? 1. No time. I need time for other parts of life. 2. I rather treat my place as home. 3. I now can enjoy cassette tapes, records, CDs, or streaming. I think I am a qualified audiophile at best, total music lover for sure. 4. I changed to use Dutch and Dutch 8c. Excellent vertical and horizontal smooth off-axis. 5. Ceiling reflections - I dun like it even if it's smooth off-axis (close to on-axis). I installed 9 RPG diffusors. That's effective enough. 6. I know some people like livelier room. I dun. Simply personal preference. Some like room like a studio, not my cup of tea either. For this question, it's a totally personal preference. Nothing can be argued. Better say how much db you wanna reduce for ceiling reflections/side wall reflections. Otherwise communication breaks down. You -9db and think it's just lively enough for Jazz Quartet. I like -18db because I like playing Muse's music. So my apology for asking a foolish question back then. To answer simply: RPG is effective in dispersing ceiling reflections. I haven't measured though. In a very small listening room, absorption may be better if you want an overall even more quieter, close-to the studio sound experience. Purely personal. Thank you. |

| [#30] 天花版吸音物料及安裝的意見 我理解佢唔係多孔式吸音物料唔需要留額外空氣層只需要有少量透氣，背面留 gap 主要係方便安裝，因為需要斜斜哋塞入去。 安裝後本體震動會有影響，所以有/冇黐實或有冇加 eva 邊時中低頻吸收會有分別。 |

| [#29] 天花版吸音物料及安裝的意見 Long long hing 通常廠方有冇一些標準數據, 例如是否應該 和天花板 有一段距離10cm..20cm etc, or directly attached to the ceiling? Thx Thx |

| [#28] 天花版吸音物料及安裝的意見 例如有啲比較輕嘅板設計包括所使用嘅物料密度預設係預咗用喺比較細嘅空間安裝喺輕鋼架天花會吸收部份低頻，送 lab. 測試吸音系數嘅公開數據係安裝喺輕鋼架嘅測試結果，如果自己獨立黐嚟安裝測出來數據尤其喺低頻吸收部份會有明顯分別。 有啲廠商可以提供唔同安裝方法嘅測試數據供參考 (當然又未必會係送 lab. 所測出嚟嘅數據，有機會只係間廠 development 時嘅自測數據)。 |

| [#26] 天花版吸音物料及安裝的意見 "Thx Thx.. 原本嘅問題 嘅原因係什麼呢..." 喱個問題最好都係等樓主親自回覆。 "2D prd 都可以好多... Are they mostly divided frk the same calculation?" 基本上都係由同一條 eqt. derive 出嚟，只不過比較 advance 啲設計過有加入 optimization 嘅算法。 另外就係有冇使用適合環境嘅物料同埋配合正確嘅安裝方法。 |

| [#14] 天花版吸音物料及安裝的意見 路過插嘴, 望勿見怪. 高音太過光輝, 甚至吵耳, 小弟小小分享 ... ... 1/ 最懶又最平既方法, 係喇叭頂舖毛巾, 毛巾舖越厚, 越吸得勁, 以平衡音色. 呢個方法斬腳趾避沙虫, 好處係順耳/冇咁吵耳, 方便同埋免費, 唔好處係無助解決噪音及出多d細節. 2/ 駁喇叭線, 有師兄已提出. 如bi wire喇叭, 試試改變接線方式. 小弟試過同朋友搞, 原本hifi舖幫佢紅黑駁晒低音, 鐵片jumper分別連接紅黑高音. 改一下駁法, 紅色駁低音黑色駁高音, 鐵片jumper保留, 低音即刻返晒黎, 音色平衡. 呢個做法又係免費, 亦可試試係咪jumper累事. 3/ 器材防震好好處理, 特別係power amp呢d大隻牛既器材, 第二係音源. 有搞同無搞防震, 差別可以大到好似換左機, 成套野upgrade左咁, 噪音少好多, 細節返返黎. 防震需要洗d錢, 搬機搬到苦力咁, 仲要試來試去交下學費. 玩掂之後, 感覺值得! 4/ 間屋亂D, 多D雜物如地氈, 堆滿既書架, 茶几上放D雜誌. 空間太空曠, 會有反射聲問題. 5/ room treatment, 聆聽空間是否太多玻璃? 係既話靠軟物料. 冚太多搞到錄音室咁, 會吸死晒D聲, 無晒生氣, 必須要慢慢試. 有D師兄在反射位求其貼張A4紙已經搞掂, 視乎現場環境慢慢試, 未必一定要大龍鳳到搞到天花凹凹凸凸. 天花燈如果係中間位, 一盞不規則形狀吊燈往往會搞掂. 6/ 線材搭配/器材搭配/空間搭配, 呢樣野真係燒銀紙! 暫不在考慮之列. 環境鬥士, 空間大小一樣有排玩 ^^ 最後修改時間: 2010-08-03 01:35:33 |
