The influence of acoustic property of fabrics made from recycled polyethylene terephthalate (recycled PET), juteand flax fibres have been studied. Six different blended proportions (100 % Recycled PET, 100 % Jute, 100 % flax, 25 %jute: 25 % flax: 50 % recycled PET, 50 % jute: 25 % flax: 25 % recycled PET, 25 % jute: 50 % flax: 25 % recycled PET) ofdifferent grams per square meter 200, 400, 600 needle punched technique non woven fabrics have been produced andanalyzed for their properties. The sound reduction of needle punched 50 % jute: 25 % flax: 25 % recycled PET non-wovenhas shown better performance among the six samples. The grams per square meter of the samples influence the soundreduction values of non woven fabric. Increase in gsm of the material also increases the sound reduction value. Among all thesamples, the 50 % jute: 25 % flax: 25 % recycled PET non-woven sample produces good acoustic property in developeddigital sound reduction tester and commercial sound impedance tube absorption co efficient value. Anova mathematical toolshows the there is a significant difference between input and output signal in the digital sound reduction tester. From theresults, It is found that the sound reduction property of non woven fabrics increases and decreases with the types of fibre andgrams per square meter of the samples. The jute non woven fabric can be used as good sound reduction material for variousindustrial applications.
