An interdisciplinary study of urban noise pollution: part II

An interdisciplinary research in two stages was carried out in Córdoba City, Argentina, in four zones with different urban noise characteristics. First, statistical noise measurements as well as a psychosocial survey, the data which were analyzed through the Multiple Correspondence Factorial Analysis (AFCM), allowed earlier approach to the subject (Part I).' In the second stage, reported in this paper, data from the previous one were studied in depth: 1) Through a Tri-Dos post factorial method based on the AFCM results, profiles of people exposed to urban noise were determined; this procedure shows to be suitable for detecting risk groups in epidemiological researches; 2) A correlation analysis among noise descriptor values and loudness judgements for certain stablished periods of the day well described the performance of indices and percentiles according to the zones, although it was not possible to find an unique predictor.
