    Road pavement develops distresses over time, which increase tyre/road noise. This work
    focuses on the impact of these distresses on environmental noise. To calculate the environmental
    noise, a method to transform Close ProXimity (CPX) measurement results into the required input for
    traffic noise models was defined and used. The tyre/road noise levels were determined by the CPX
    method for three types of pavement, with three types of distress, at three di erent speed levels. The
    study was carried out in the city center of Guimar{\~a}es, a medium-sized Portuguese city. Using the
    NMPB model, 18 noise maps were produced for the passing of one single vehicle, taking into account
    two levels of distress (50\% and 100\%) for the pavement. The presence of distresses increased the
    noise, calculated at control points, by up to 7.1 dBA, and the percentage of the population exposed to
    levels over 45 dB was more than 11\%. It was shown that pavement maintenance at early stages of
    distress development is, particularly for low-speed roads, very important to reduce environmental
    noise and population exposure. A comprehensive selection of the type of surface and speed control
    policies can mitigate the impact of a lack of maintenance.
