Bass Trap: Volume Hidden in the Corners

Present the treatment of the four vertical corners of the space in a sectional view: each corner is sealed by a diagonal panel from floor to ceiling, forming a triangular cavity between the panel and the two walls, with a depth of 600mm. The cavity is filled with low-density sound-absorbing cotton and equipped with internal baffles. Since low frequencies accumulate most severely in corners, these invisible volumes are key to controlling low-frequency rumble. The diagonal panel itself is a perforated wooden board or acoustic fabric, appearing externally only as if the corner has been chamfered. The sectional view clearly indicates the cavity, filling material, and panel. Avoid: corners being right angles, insufficient cavity depth, filling material drawn as solid, panel made of sound-impermeable solid board.

以剖視的方式呈現空間四個垂直角落的處理:每個角落被一道從地到頂的斜向面板封起來,面板與兩道牆之間形成一個三角形的空腔,深度達 600mm,腔內填滿低密度的吸音棉並設置內部隔板。因為低頻在角落累積最嚴重,這些看不見的體積是控制低頻轟鳴的關鍵。斜面板本身是穿孔的木板或聲學織品,外觀上只像是把角落做成了斜角。剖視圖清楚標示空腔、填充材與面板。避免:角落做成直角、空腔深度不足、填充材畫成滿實心、面板做成不透聲的實板。
