Paddy fiber as an alternative sustainable acoustic absorber material

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...
