Sonic City is presented as an important benchmark in the space-time evaluation of the urban soundscape. From its theoretical debate and methodological aspects, it invites to reflect in depth on an issue that has been timidly addressed in various latitudes, especially in Latin America. Despite the fact that there are some studies and regulations in this regard, their efforts are generally focused on the biased view of the physical factor, which, starting from predetermined limits, already considers talking about "urban noise" problems, without going beyond the measurement of traditional acoustic parameters (dBMin, dBLeq and dBMax). For this reason, the sensory components of sound are omitted: that is, its perceptual factor, understood as a reality that originates in the interaction between the human being and his closest acoustic environment. In this sense, the value of the sound landscape in urban planning processes lies in the fact that the senses and emotions are the access route to the audible richness of the tangible space in which one lives; In this way, it is recognized that the sensory activity of the acoustic environment provides useful information for improving the quality of life in the city. Indeed, this book questions the ways of understanding the broad spectrum of patterns and perceptions of urban sound, with the aim of providing healthier and more balanced soundscapes to citizens.
