In a SmartCities world, with the citizen in the center of all the decisions, the measurement of environmental noise cannot be limited to provide an equivalent level captured over a certain time in a place of interest. By means of WHO reports and other studies, we know that the type of noise (traffic, anthropomorphic, industrial, etc.) has a different impact on people and that it is important to identify the source of the measured noise levels. In order to facilitate this work for the competent authorities, in Andorra a 3D City model platform is used to visualize acoustic measurements carried out at three strategic points in the country. The platform represents the measured noise differentiating the type of noise, the equivalent acoustic level it is providing and the salience of the event with respect to background noise by means of the calculation of the Signal-to-Noise Ratio, providing a wider and more complete amount of information to allow to decide policies to minimize the impact on people.
