Corn cob particleboard samples sized 3 cm 100 cm 50 cm (thickness width height), Fig. 1, were processed specifically
for the impact sound insulation tests and according to the manufacturing process described above. The curing occurred under controlled thermo and hygrometric conditions (i.e. laboratory conditions). The samples were pressed during this stage. The corn cob particleboard samples presented an average density of 334 kg/m3 (i.e. similar to cork for instance) and were completely dried during the tests.
