pavement acoustically reinforced with it. Therefore, impact sound
insulation tests were performed following the standard NP EN ISO
140-7 [26] and the rating of impact sound insulation was calculated
following the standard ISO 717-2 [27]. The ambient noise
of the receiving room, the impact noise in the receiving room for
the scenarios of the original pavement and of the sound insulation
reinforced pavement with corn cob panel, and the reverberation
time were acoustic measures which it was necessary to obtain.
Based on these experimentally obtained measures the impact
sound insulation of the pavement, for the two considered scenarios,
was then numerically quantified. The results indicate a 30 dB
gain in terms of impact sound insulation capacity by applying
the corn cob panel on the floor of the emitting room. After comparing
this gain with the respective ones related to the most currently
applied 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
