This paper presents six environmental noise indicators and two fuzzy acoustic indexes for urban spaces integrated with a permanent monitoring system. Likewise, they can help the management practices of land traffic and other noise generation sources in cities. The environmental noise indicators are defined by combining the equivalent continuous sound levels with A-weighting for time intervals of five, thirty, and sixty minutes and the non-harmful values set by national and international standards. Exposure and severity are the fuzzy indexes obtained with a model that weights the six environmental noise indicators utilising membership functions, rules and the centroid defuzzification method. The two fuzzy indexes are evaluation metrics of the social-urban acoustic impact that monitoring and evaluation programs can apply for standard time intervals or other time selection.
