高層建築物內的隔間,因結構及施工方面之需求,漸漸採用乾式輕量隔間
牆,因其重量輕,在理論上,隔音性能比傳統之磚牆與RC牆差,況且國
內缺乏乾式輕量隔間牆之基本隔音性能資料;本研究乃針對這類構造,蒐
集市面上常用之材料,進行隔音性能之測定,比較實測值與質量法則之差
異,並分析影響透過損失的因子。本文主要內容分為四部分: (1) 調查
與分類─本文依據牆體的組合方式,將89片試體分為①單一均質板牆②疊
合牆③阻尼約束牆④空心牆⑤剛性三明治牆⑥蜂窩三明治牆⑦彈性三明治
牆⑧中空雙層牆⑨中空填棉牆等九類。 (2) 隔音性能量測與評估─在國
立成功大學音響實驗室應用『音強法』,量測試體 1/3八度音程各頻率之
透過損失值。就D評估曲線系統 TLD值而言,以麗光板中空雙層牆之隔
音性能最差,只有TLD-15。隔音性能最佳者為雙面雙層石膏板中空填棉
牆,可達TLD-49,其次為雙面雙層石膏板中空雙層牆(TLD-46)與雙面
雙層礦岩板與石膏板中空填棉牆(TLD -45),此三片試體都屬於雙層牆
。若要再提高隔音性能,可將中空填棉牆之骨架改為獨立間柱式,或者將
雙層牆與其他類牆組合成多層牆,隔音性能可達TLD-50以上。 (3) 隔
音頻率特性與透過損失─九類隔間牆之隔音頻率特性,可歸納為①單層基
本型②重合效果緩和型③高低頻加強型④雙層基本型等四種。本文就125
Hz、500Hz、2KHz三個頻率,比較透過損失實測值與質量法則計算值,以
雙層牆類試體差異較大,頻率愈高,實測值與計算值差距愈大,尤其在2
KHz,差距20∼30dB,而且實測值高於計算值,乃空氣層與中空層填充吸
音材之效果。 (4) 隔音性能影響因子─將輕量隔間牆構造因子面密度、
牆體總厚度,分別與隔音性能 STC值進行迴歸分析,其中空心牆與蜂窩三
明治牆兩類試體,不論是面密度或者厚度之迴歸,簡單判定係數都很高;
單一均質板牆試體面密度對數值與 STC值的迴歸分析結果與質量法則吻合
;但其餘試體迴歸簡單判定係數都不高。必須加入構造形式的因素,後續
研究可再深入探討其構造因子對隔音效果之貢獻率作為提高隔音性能之參
考。
For the need of structure and constructing, partitions of high-
rise buildings are gradually made of light-weight walls. Its
merits of light-weight theoretically cause less property than
masonary materials─brick or concrete in the performance of
sound insulation. Furthermore, there is lacking sound
insulation data of light-weight walls interiorly. The aim of
this research is mainly in studying the performances of
commonly available partition on the market, the differences
between measurement and calculation and the factors of sound
transmission loss. The main contents of the thesis are outlined
in four parts as follows: (1) Investigation and Sortation─
There are 89 pieces of tests to be distributed into nine types
according to the combinations of partitions. (2) Apply "sound
intensity method" to measure sound transmission loss of the
partitions, and use D-curve system to assess their sound
insulation. Among these partitions, the worst one is the
formica hollow wall with wood skeleton structure. The best one
is the hollow wall filling with glasswool made of double gypsum
panels. (3) Sound insulation performances of these partitions
can be generalized into four types. They are ①single panel②
coincidence with smooth curve ③coincidence with sharp curve ④
double panel. Comparing the laboratory measurement with
calculation of mass law , when frequency is higher, the
difference is more. For example, at 2KHz, there''s a distance of
20-30dB between them, because the hollow space is filled with
glasswool or rockwool. (4) The factors of sound transmission
loss,"Surface density" and "Total thickness" of partitions, can
be analyzed with STC value in regression. The results of single
panels are congruous with the mass law. The same as another two
kinds of light-weight walls ,but the other''s coefficient of
determination is low. Considering the other factor of
transmission loss to find out the important factor helping for
sound insulation of partitions.
