Abstract

The usage of synthetic materials in the production of sound absorber can cause the pollution to the environment and affect to the human health. In order to prevent this problem, many researchers have been done to the natural material to get their acoustical properties. This natural material is sustainable and biodegradable. It not causes pollution to the environment during its process. This thesis is study about the acoustical properties of the bamboo materials. Bamboo with the smaller diameter is one of the most wasted natural materials that not been used properly by the human. Bamboo is design and fabricates in the form of sample for the test to investigate their absorption coefficient using the impedance tube method. Various parameter of bamboo sample has been test in order to know factor that affecting the sound absorption of bamboo material. The result is analysed and compare with each parameter to find which one is suitable to use for production of sound absorber. A good absorption coefficient of material found is above 0.5 with the frequency of 1 kHz and above.
