traditional insulation products in the building industry
(e.g. glass wool and expanded polystyrene) and also to other alternative
natural sound insulation products (e.g. kenaf, coco fibre,
sheep wool, cork and cellulose), the acoustic potential of the proposed
product is highlighted. Nevertheless, further research is required
in order to evaluate the exact values of the impact and
the airborne sound insulation, and the sound absorption coefficients
of the proposed manufactured corn cob particleboard. In this
case, laboratory test facilities with suppressed flanking transmission
between rooms and a reverberant room are required. At the
same time, a parametric study relating the granulometry of the
corn cob particles and the thickness of the panel with the sound
insulation performance is also required.
