The interest in the use of new green materials with considerable sound-absorbing power is no longer limited to the building sector but increasingly involves the automotive sector with attention focused on the possibility of improving the acoustic comfort of land vehicles (cars, buses) ensuring at the same time full ecological sustainability. The present work describes the expected soundproofing properties of a plant material and the measurement set-up used for its characterization and comparison with other types of material typically used to limit the impacts of the main acoustic sources in the passenger compartment of land vehicles. Finally, the experimental results of the characterization measurement are discussed in terms of the future automotive applications.
