| 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 found particularly above 2000 Hz and is comparable against that
from the classical synthetic absorber. |
