本研究探討木質裝修材配置對室內聆聽音樂空間聲場之影響。研究先藉由現場聲環境量測及聲環境軟體模擬比對結果,確認電腦運算之準確性,再於電腦聲學模擬之空間中建置變因,進行室內聆聽空間之聲學特性探討。 本研究依據CNS 9056聲學-迴響室之吸音量測規定,測得木絲水泥板之吸音係數,並將參數輸入電腦模型材料設定中,探討木絲水泥板裝修及配置位置等數組變因條件對住宅聆聽室聲場之影響。結果顯示,揚聲器間距越近,初始時延差越小,聆聽者對於聲像誤差偏移之感受也越不受影響,且可使側向聲能反射趨於穩定;而聆聽接收位置距離多聲道揚聲器發聲源越遠,其初始時延差越為降低。 在聆聽空間前、後方裝設木絲水泥板,可獲得較佳之側量聲能表現,且對於整體迴響時間有較高之控制力。而影響側向反射因子之主要變因,主要是以聆聽位置之側方及後方牆面為主,且反射面與接收點之距離愈近,其側向聲能愈強。改變上方天花板之傾斜方向對側向反射因子影響則較為有限,但對於提高音樂明晰度之效果最為顯著。
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 Model Acoustics, capture characteristics from two subjects for development acoustics panel with function. Examining the scattering coefficient effect with ISO 17497-1:2004, 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.
