Study on applying fibers in nun non-woven fabric products. With the objective to try forming non-woven fabric from fibre compound ester Lee enough fiber, Needle punching nun in the process to test the sound absorbing properties and physical properties of non-woven fabric. By providing sufficient fibre Lee ester blended with fibers nun in the ratio of 100:0, 90: 10, 80: 20, 60: 40, 70: 30 and 50: 50 through the opener and fibers, fibers, and then pass through a sheet, to make fiber breaking of filaments (Web) after it's mechanical bonding process using a needle puncture (Needle punching) at 2 speed.5 ft/min and 5-foot speed/min. Test the sound absorbing properties of frequency 150 – 4000 Hz and physical properties Testing found that the non-woven fabric from polyester fibre blended with enough fiber ester nun in the ratio 60:5 speed 40 ft/min with a maximum sound absorption properties
