Recent studies on community noise in bahia blanca city (argentina)

摘要

Based on the public demand through noise complaints expressed by the neighbors to the local newspaper, radios and TV, a research project on community noise is being performed by the authors trying to find a practical methodology for the acoustic characterization of medium size cities (50,000 - 500,000 inhabitants). One of the research steps was to hold an environmental noise survey (more than 400 questionnaires were filled) in order to know the subjective opinion of the people about their neighborhood, main noise sources, level of annoyance, etc. Simultaneously, measurements were taken to objectively evaluate in-situ the actual noise levels. The present paper briefly shows preliminary results on the correlation between the subjective opinions and objective measurements.
