Summary: | The use of synthetic materials as acoustic absorbers is still applied
extensively in building industry. These non-biodegradable materials do not only
cause pollution to the environment, but also contribute significantly in increasing
the CO2 causing the effect of global warming. Therefore researchers have now
driven their attentions to find sustainable and eco-friendly materials to be an
alternative sound absorber. This paper discusses the use of natural fibers from
dried paddy straw as a fibrous acoustic material. Since this is one of common
natural waste materials found across South East Asia, the usage will also
minimize the production cost. A panel sound absorber from paddy straw is
fabricated and its acoustic properties are investigated through experiment. Good
acoustic performance is obtained and is comparable against that from the
classical synthetic absorber. |
