Abstract Scope Noise pollution generated in the city is currently one of the main environmental problems. Different studies try to address this type of pollution, which focuses mainly on noise sources from road traffic. The following work seeks to find solutions to this problem. Understanding that today a large percentage of car traffic noise is generated by the interaction between the tire and the ground. This work considers the possibility of mitigating this type of noise through the implementation of sound-absorbing facades in urban canyons. For this, it is planned to use pumice stone with an air gap of 1 cm. To characterize the conditions of an urban canyon, information from a noise monitoring station of approximately 3 years was used. To evaluate the absorption conditions of the compounds, an impedance tube was used. Finally, to show the absorption of the facade, the Sabine equation was used. The results obtained show that absorption coefficients of up to 0.45 can be achieved in the 500 Hz band. The implementation of pumice stone with an air chamber in 90% of the facade of the buildings that form an urban canyon can achieve reductions of up to 0.17 s in the RT60 for the 500 Hz band.
