This research focuses on an analysis of the perception of urban noise in the daily lives of the residents of two different areas: (1) a residential neighborhood and (2) a city center, respectively, considering (1) an acoustically ideal urban environment and (2) an acoustically polluted urban environment. To this end, a random sample of individuals from both areas was asked to fill out a questionnaire. Sound pressure levels were also measured in each of the evaluated areas. The World Health Organization (WHO) considers a quiet area as one in which the measured sound pressure level is up to 55 dB(A). The average measured sound pressure levels were 53.5 and 72.9 dB(A), respectively, in the quiet area and in the area considered acoustically polluted. Data were subjected to a multivariate factor analysis. The main complaints reported by the interviewees were as follows: headache, irritability, poor concentration and insomnia. Interviewees in the city center stated that street traffic noise was the main source of annoyance, while the residents of the residential area stated that the main source of discomfort was air traffic noise.
