Abstract

ABSTRACT: Purpose: to analyze the knowledge, behaviors, and attitudes of students on noise.

Methods: We used an observational method study, in 32 Schools from Itajaí/Brazil, with a convenience sample, comprising 1,835 students, 45.7% females and 54.3% males, mean age of 11.53 ± 0.8 years, was conducted. The Portuguese version of Dangerous Decibels® questionnaire was applied. For the data analysis, descriptive and inferential statistics were used, significance level of 5%.

Results: A large part of the sample part of the sample had harmful hearing habits; 62.6% reported knowledge on the subject, but only 25.4% answered the questions on the theme correctly; 58.9% reported that they did not know how to protect hearing if necessary. Regarding sex and age: males have more hazardous hearing habits (p < 0.001) and tinnitus complaint (p<0.001) and females have more knowledge (p < 0.001) and the intent to wear hearing protection (p<0.001), greater intention to wear hearing protection among younger students (10 and 11 years old) (p < 0.001), and the older ones (12 to 16 years old) get more exposed to noise (p < 0.001), and there are more tinnitus complaints (p < 0.05) among them.

Conclusion: A large part of the students in the study has hazardous noisy habits and scarce knowledge on the theme, with males and older subjects showing the worst attitudes and behaviors in face of the potential hearing risk caused by exposure to high noise levels.
