The present study investigated the psychosocial complaints related to urban noise among the population of Curitiba. We used a questionnaire of closed-set questions to collect data on demographics and psychosocial reactions to environmental noise when subjects are at home. Eight hundred and ninety-two individuals (892) participated of the study. The main noise sources associated with discomfort or annoyance were traffic noise (67%), neighbors (33%), sirens (23%), animals (21%), and construction (21%). The main psychosocial complaints were annoyance (55%), disrupted concentration (28%), sleep disorders (20%) and headaches (19%). The data confirm that noise pollution has an influence on the quality of life of the population as manifested by several psychosocial complaints that could have a negative impact on the health and well being of populations.
