Abstract
Different urban environments were analyzed acoustically, using 32 recordings obtained with binaural techniques of recording and reproduction. The relationships of the perception of pleasantness/unpleasantness as described by a sample of 25 inhabitants of these urban environments with two psychoacoustic parameters (loudness and sharpness) and the traditional measure of equivalent sound level (dBA) were analyzed in two forms, one using a verbal scale, and the other a numerical value for that perception. Highly significant correlations were found between the perception of an environment as very unpleasant and the parameters considered for its acoustic characterization. The mean of the numerical value used to express the sensation of liking was significantly correlated with the three sound parameters.
