具置物機能之聲學擴散板產品開發-以木質聲學擴散CD架為例
Products Development of Acoustical Diffuser with Setting Function - Using Wodden Acoustical CD Diffuser as an Example
摘要
聲學產品對於室內聲學設計是一項用來控制室內聲場的重要因子，本研究探討以邏輯思考的方式，由平面至立體的構成以致於物件在時間與因果關係的變化以五個設計維度進行分析；承續既有研究並探討有關於利用設計維度的邏輯思維來串連「產品設計」、「室內聲學」二門科學，並篩選二門學科的特點來開發「聲學擴散板」之衍生產品，並依照ISO 17497-1標準散射係數量測方法來進行性能測試，提供散射性能數據作為設計室內聲學產品及裝修配置之參考。實驗結果顯示擴散CD架的散射係數測試在中低（200 ~500 Hz）與中高頻（630~1.6k Hz）平均產生高於0.5的散射效果，最高為0.88與0.85在400與500 Hz兩點頻率產生，與傳統單純構造變化為主的聲學擴散板之散射效果接近，證明透過五個維度的分析能獲得多面向的參考依據，在產品實際生產前能預先做出各種不同成果之模擬除節省多樣式原型的成本外，聲學擴散板與生活產品結合能產生良好的散射效果並獲得實用的置物機能。

Acoustics products were the effect of controlling affect on sound field. This study analyzed products before the entity created with logical thinking, the relation between cause and effect total five design dimensionalities to estimate design process. Inherited series scattering coefficient studies and used design dimensionality to combine Product design and Room acoustics, capture characteristics from two subjects for development acoustics panel with function. Examining the scattering coefficient effect with ISO 17497-1, provided the products scattering data for acoustics design and interior decoration. Result showed the scattering coefficient of acoustics CD diffuser on low-mid frequency (200-500 Hz) and mid-high frequency (630-1.6k Hz) over 0.5, the highest peak on the 0.88, 0.85 of 400 and 500 Hz, effects nearly close the traditional diffuser, It proved combined the acoustics and living products had scattering performance and setting function.
