<p>A sound absorption panel is designed as a sandwich panel, consisting of a rear plate (1) made preferentially of a glass-reinforced concrete and surrounded by a border (2), made preferentially of the same material, and of some transverse ribs (3). Sound absorption elements (4), made preferentially of rockwool, are inserted between the border (2) and the ribs (3) and are covered by a protective plate (5), preferentially a wood-cement panel which is covering the complete inner dimensions of the border (2) up to its wall. A grid (6) (or ribs respectively) is laid over the plate (5) and executed flush to the border (2) and thus to the rear plate (1).</p> |
