Assessment of social noise exposure in Chilean youth

Abstract

Introduction: Exposure to leisure activities-related noise and its effects on human hearing, e especially in young adults and adolescents, represents a problem to which society is more and more sensitive. For this reason, we carried out a study in which we compared the noise level to which a group of young Chileans was exposed, with similar studies from Europe. Aim: The purpose of this study was to identify leisure activities that could pose a risk of inducing hearing loss in the long term. A second aim was to study the weekly noise exposure levels derived from the most frequent teenager leisure activities in our society. Material and Method: A prevalence study was carried out by surveying 243 young individuals from Santiago. Weekly noise exposure level was calculated considering both the dB intensity of each activity and the time exposed. Average social noise exposure registered was 40 hours per week. Intensity of the noise level per week was compared with the work risk threshold of 85 dB. Results: Risk activities such as attending rock concerts, discotheques or pubs were identified. The survey results show a 30% of Chilean adolescents exposed to noise levels above the threshold considered a risk when exposed to it weekly. Conclusions: A comparison of our results with those from the literature shows that the risk of damage due to noise exposure is smaller in our young population than in Spanish or Finnish teenagers. Further studies are needed to establish causal relationships with objective measures, allowing for education and prevention.
