摘　　要：AMF Tacet可以帮助大片的、不规整的天花板表面实现良好的室内声学效果，该天花板系统以均匀无缝的外观和卓越的吸声性能为特征，吸声系数和降噪系数可分别达到0.75（MH）和0.80。该结构由集成了Rg4—10盲孔的24mm厚的矿棉吸声板组成，它被螺丝固定在一个带有游标悬架的CD底座上。两层声学效果石膏涂层能够保证天花板呈现均匀的外观。With AMF Tacet, large, unstructured ceiling surfaces with good room acoustics can be realised. The ceiling system is characterised by a homogeneous, jointless appearance and offers remarkable sound absorption properties with 0.75 （MH） and an NRC value of 0.80. The structure consists of a 24-mm-thick mineral tile with an integrated Rg 4-10 blind bore, which is screwed onto a CD substructure with nonius suspension. Two acousti- cally-effective plaster coatings ensure a homogeneous appearance.
