吸音構造常用於調整室內空間之吸音力,進而改善室內音響效果,
空氣層常設置於吸音構造中,以達到中低頻的吸音效果。然而空氣層的
設置一般多由表面材與構造體 (背貼材),或背貼材與構造面 (背貼材)
以間隔一定空間裝設所產生。回顧國內外對吸音構造與吸音特性影響之
相關研究,皆以表面材與構造體平行裝設的方式為探討對象較多,當構
造之表面材不平行於壁面或背貼材裝設時,即表面材與壁面或背貼材間
所產生之非整型空氣層中,並未探討其吸音特性的影響。因此,本研究
彙整常用之吸音構造,以單軸傾斜之非整型空氣層為研究對象,由傾斜
平面夾角 (0 度-20 度)、傾斜平面跨距 (60 公分-360 公分)與空氣隔室
之設置做為空氣層形狀為主要變因,搭配非整型空氣層的板狀構造與穿
孔板構造進行吸音係數之測試,由測試結果顯示非整型設置於吸音係數
的影響,及空氣層隔室設置於非整型空氣層之吸音係數影響兩部分,探
討非整型空氣層之吸音特性。
實驗結果顯示,隨著角度加大,非整型之設置對構造吸音係數產生
較大之差異;伴隨著跨距加大,發現至180 公分以上非整型之設置對構
造吸音係數已較無影響;此外,非整型設置對板狀構造造成較大之吸音
係數差異,於穿孔板構造吸音係數差亦多於0.1 以內。而空氣隔室的設
置於120 公分以上跨距之吸音構造吸音係數較無明顯影響,僅於60 公
分跨距之200Hz 以下頻率有較明顯影響。
Air layer with u irregular shape in sound absorbing structure is formed by
different structure mode of materials. With building multiform interior space
by materials and structure mode, it makes the shape of air layer between the
facing and the structure of building to be irregular shape.
According to related study of absorbing structure, it shows less
information about the influence of air layer with irregular shape. The factors
of sound absorption of absorbing structure were focused on absorbing
structure which facing paralleled structure of building in past research. For
searching the influence of sound absorption of absorbing structure caused by
the air layer with irregular shape, the subject in this study is set as the air
layer with irregular shape which facing tilts with single-axis. The factors of
air layer with irregular shape are the angle between tilting facing and
horizontal face, the length of span of tilting facing, and if the setting is that
the air layer is divided into several parts not to be interlinked. By these
factors the sound absorption characteristics of air layer with irregular shape
are shown.
The results of the measurement in the study are displayed in two parts.
One is the influence of absorption coefficient caused by irregular shape, and
the other is the influence of absorption coefficient caused by setting that the
air layer is divided into several parts not to be interlinked. The results reveal
that there is more obvious difference of absorption coefficient as the angle
of air layer with irregular shape is bigger, and that there is less influence of
absorption coefficient as the span of tilting facing becomes bigger up to 180
centimeters. In addition, the irregular shape causes larger difference of
absorption coefficient to the panel structure, and the difference of absorption
coefficient of structure with perforated facing is within 0.1. Furthermore,
there is a little influence of the setting that the air layer is divided into
several parts not to be interlinked only in frequencies below 200 hertz as the
span of tilting facing is 60 centimeters.
