摘要：Jenis atap berbahan metal banyak digunakan pada bangunan dalam berbagai skala,terutama pada bangunan bentang lebar.Atap metal yang banyak dipergunakan ialah dari bahan zinc-alume yang kinerjanya baik dibandingkan material metal lainnya,terutama dari sisi kekuatan/kelenturan struktur,kemudahan konstruksi dan umur material yang panjang.Namun dari sisi peredaman bunyi,atap zinc-alume masih perlu ditinjau baik kinerja atap beserta upaya insulasinya terhadap structureborne-noise (dalam hal ini impact-noise) dan airborne-noise.Jenis insulasi yang diteliti meliputi,cat atap (Orca Zinc Coat),glasswool-rockwool dan styrofoam.Pengukuran menggunakan sumber bunyi pink noise dalam frekuensi 125 Hz– 4000 Hz.
其他摘要：Sound Reduction Study of Insulator of Zinc-alume Metal-roofing.Metal roofing is a common upper-structure of widespan building.The metal material usually used as roof covering is zinc-alume;which has better performance in strength，easy-construction and its durability than other metal material.Although it has good structural performance,its performance as a sound reduction to reduce noise to the room beneath still need to be studied further.Therefore this research aimed to study how zinc-alume and its insulator perform through air-borne noise,besides structure-borne/impact noise.Insulator has been studied here are the Orca-zinc coating,glasswool,rockwool and styrofoam.The measurement done in a reverberation chamber,with pink noise source in 125 Hz- 4000 Hz frequency.
