This work presents the results of the development of agglomerated cork floating floors through the optimization of their acoustic performance, with the goal of improving sound insulation to structure borne noise. Percussion tests were performed in 26 floors in the reverberation room of FEUP, and with the support of the cork company SEDACOR. The results showed that the best acoustic performance is attained with the combination of the "012", "plywood" and "51 PL"/"12 PL" or "012", "MDF" and "25" products. It was found that other underlay shapes can substantially improve sound insulation in medium-high frequencies. For a better comparison of results an adaptation of the current standardization is suggested, through the use of the A-weighting curve.
