Daftar Isi:
- In building design, architect should consider acoustics condition; besides other conditions like structure, mechanical-electrical etc. The term acoustics can be used to describe the study of sound in general, but the subject of acoustics is concerned with the control of sound within a room. The general aim of acoustics is to provide the best condition for the production and reception of sound such as music or speech. Wood in general has been used for acoustics material, because their ability to absorb a significant amount of incident sound in a room. Wood as an acoustics materials are very flexible applied in a room; like ceiling and walls surface, floor platforms, or other components depending on its performane requirements. Otherwise, in this research is selected softwood (Agathis loranthifolia) which one of fast growing tree. The result of this research showed noise reduction index between 0.10 -0.18; tranmission loss value 18.31 – 36.73 dB; and absorption coefficient of sound 0.12 – 0.22.
