The noise pollution generated in the city is currently one of the main environmental problems. Different studies try to address this type of pollution, which above all focuses on sources of traffic car noise. The following work seeks to find solutions to this problem. Understanding that today a large percentage of traffic car noise is generated by the interaction between the tire and the ground. The possibility of mitigating this type of noise through the implementation of sound-absorbing facade baseboards is proposed in this work. For this, it is expected to use binder epoxy resin that, mixed with nanoparticles of rice husk, manages to mitigate environmental noise conditions in urban canyons. To characterize the conditions of an urban canyon, information from a noise monitoring station from around 3 years was used. To evaluate the absorption conditions of the compounds, an impedance tube was used. Finally, to show the absorption of the baseboards, a 1:10 scale model was used, and modeling was carried out in Catt Acoustic. The results obtained show that absorption coefficients of up to 0.5 can be reached in the 1 KHz band. |
