The test results showed that non-woven cloth of ester polymer composite fiber ratio 60: 40 with high sound absorption coefficients, and is a sound absorbent material material prunes (Dissipative or Porous Absorber) with non-woven fabric with sound absorption coefficient value is quite high at low frequency and is likely to rise at a high frequency. By 2.5 ft/min speed and 5 ft/min with sound absorption coefficient values similar to and from the level of reduction coefficients of non-woven fabric was found to be sound, with values in the range of 0.09-0.1 is suspension material. Suitable to be used in lining materials, high frequency sounds.
