impact sound insulation tests have been performed in which the acoustic insulation gain of a pavement reinforced acoustically by a 3 cm thick corn cob particleboard was assessed. The obtained acoustic insulation gain was then compared with the respective ones of traditional sound insulation products (e.g. glass wool and expanded polystyrene) and also with different alternative natural sound insulation products (e.g. kenaf, coco fibre, sheep wool, cork and cellulose). The obtained results indicate that the proposed product may also have an interesting acoustic behaviour for building purposes. This conclusion is even more interesting taking into account that corn cob is a natural, organic, renewable and local raw building material.
