Abstract

The used of synthetic materials as acoustic absorbers are still practiced extensively in building industry. This is because the increasing of noise level affects people not only in the industry, but as well in the living environment. The high cost involved in the construction and renovation of noise barriers makes the growth of sustainable barriers necessary. Thus, researchers have now driven their attentions to find sustainable and eco-friendly materials to be an alternative sound absorbing. This paper discusses about the uses of reed grass to be a sustainable sound absorbing. The usage this fabric actually will also minimize the production cost since the reed grass is one of common natural waste materials that found across South East Asia. The sound absorption properties of reed grass have been investigated through experiment. Their acoustic properties were measured by using an impedance tube instrument. In summation, the characteristic impedance and the propagation constant of the fabrics were measured. The results shows that the reed grass has excellent acoustical performance to be sound absorbing fabric.
