Sound pollution can be minimized by noise intensity using sound absorbing material. Nonwoven fabrics are the material most widely used for acoustic applications. This research investigated about absorption coefficient of nonwoven pineapple leaf fiber (PNW), and its layered combination with double weave (PDW) and tricot knitting fabric (PTK). The variation of fabric will be tested for sound absorption coefficient using an impedance tube. Absorption coefficient test results showed there was an effect in absorption coefficient on nonwoven with layered.
