The Ceiling of the Swimming Hall: Sound Absorption, Reflection, and Shimmering Water Light

Indoor pool ceiling: sound absorption, reflection, and shimmering water light
The most challenging aspects of an indoor swimming pool are sound and humidity, both of which are addressed by the ceiling. The ceiling is made of continuous wooden or metal grilles, with gaps between the grilles and a sound-absorbing layer behind them, so there is no harsh echo in the space, and the sound of water is soft. The grilles are oriented perpendicular to the swimming lanes, creating a clear rhythm. Light reflected from the water surface shimmers on the grilles, becoming the most dynamic element in the entire space—thus, the ceiling is not just a background, but a protagonist. The walls are kept plain, drawing attention upwards. Few people, with only slight ripples on the water surface. Shoot from a low angle at the poolside, capturing the rhythm of the grilles, the sound-absorbing layer behind, and the shimmering water light simultaneously. Avoid: a flat white panel ceiling, using glossy reflective materials, adding many downlights, or a completely still water surface without light and shadow.

室內泳池最難處理的是聲音與濕氣,而這兩件事都落在天花上。天花做成連續的木質或金屬格柵,格柵之間留縫,後面是吸音層,因此空間裡沒有那種硬邦邦的回音,水聲聽起來是柔的。格柵的方向與泳道垂直,製造出清楚的節奏。水面反射的光在格柵上晃動,成為整個空間最活的元素——天花因此不是背景,而是主角。牆面維持素淨,把注意力留給上方。人少,水面只有輕微的波動。從池畔仰角拍攝,格柵的節奏、後方的吸音層與水光的晃動同時可見。避免:天花做成平整的白色板、使用亮面反光材、加設大量筒燈、水面完全靜止沒有光影。
