Sound Absorption Properties of Acoustical Particleboard with Sawdust and Rice Straw

Abstract

Agricultural and industrial waste are typically disposed of by burning. As
a result, it will indirectly contribute to the release of carbon dioxide into the
atmosphere, further polluting the environment. Previous research has found that these
waste materials have the potential to be used in the production of acoustic panel
boards. This project investigates the use of agricultural waste rice straw and industrial
waste sawdust as basic materials in the production of acoustic panel boards. Both of
these materials will be reinforced with an epoxy resin adhesive. The tests such as
water absorption test, bending test and acoustical properties will be carried out and
will be compared with the standard for particle board which is JIS A 5908 (2003),
ASTM D1037 and ISO 11654 (1997). The sandwich particleboard made from coarse
rice straw and sawdust was the best and recommended for the manufacturing process.
This sandwich particleboard was a higher sound absorption coefficient than the other
sample. The recommended sandwich particle board made from rough rice straw and
sawdust has been defined in terms of its ability to absorb sound, be durable, and can
partially or totally replace wood particle board and insulation board in wood
construction.
