Today much importance is given to the acoustical environment. Noise control and its principles play an important role in creating an acoustically pleasing environment. The main objective of this study is to control excessive noise using natural fiber and synthetic non woven as sound absorbing material. Three different synthetic non woven materials were used (polypropylene: polyurethane: polyethylene) in three different ratios (3:1:1, 3:1:2, 3:1:3) as composite were prepared (belt calendaring process) for the analysis of sound absorption (impedance tube method). The best resulted sound absorption ratio material was selected to analyze flame retardancy with natural banana fabric material finishing (belt calendaring process) onto the higher thickness side of the composite. The sound absorption ability of the composite resulted that the ratio 3:1:3 possessed higher sound absorption ability when compared with other two ratios hence banana fabric was coated onto the polypropylene side of the composite. Flame retardancy test resulted that the sound absorption composite is a class I fabric where flame persisted above 7 seconds. As a final objective, this research describes sound absorption material can be made into large variety of sound absorption materials and acoustic partitions for reducing background noise.
