This paper presents the acoustic properties of rubberized concrete mixes with and without nano silica in terms of sound absorption and transmission loss in the audio frequency range. It shows that incorporating nanosilica and rubber into conventional concrete increases acoustic properties of the materials. The modeling of transmission loss performance of rubberized concretes allows the reproduction of their experimental behavior. This article presents the results obtained by varying the amounts of rubber and nano silica. However, a more complete analysis of the properties of the materials is missing, like their density, their porosity, etc. These results are basic and easy to obtain and this could also make it possible to enrich the models and to be able to discuss the results. Without these additional results, the article can be summed up as a test report and can not be published.
