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 product is highlighted.
