According to [25] the impact sound insulation test is probably
the most currently applied in the context of natural and recycled
sound insulation products because these products are very likely
to be applied as a resilient layer of floating floors. This test was also
adopted here to evaluate the sound insulation potential of the corn
cob particleboard. The standards [26–29] were followed. The
experimental setups are crucial stages for the success of this study
which is described in detail in the following sections. Some
adopted experimental simplifications are also used.
