Abstract

This work presents urban noise data obtained in a survey where sound pressure level (Leq), for the 24 hours of a typical week day (work day), was collected in a number of selected points in the city of Porto Alegre, State of Rio Grande do Sul. The information was processed statistically, compared with other available data and with the results obtained through the application of prediction equations for urban noise. The methodology is similar to one adopted for characterizing urban noise in several Spanish cities, where monitoring periods of 24 hours, allowed a high precision in prediction models and the visualization of hourly patterns for the selected urban space [7]. Fourteen locations were monitored, in areas of the city with different densities of buildings, making possible the recognition of different patterns of noise associated with such areas.
