“…The greatest difficulties of the workers verified in Questionnaire A, with mean scores <3 (inappropriate), occurred in the following themes: Intention of preventive behavior (question 17), Self-efficacy of hearing protection use (questions 9 and 12), Habits harmful to hearing (questions 23 and 24), Knowledge about the effects of noise on health and hearing (questions 28, 29, and 31), Knowledge about hearing diagnosis (questions 33 and 34), and Knowledge about actions of the Hearing Preservation Program (HPP) (questions 35 and 36).

In the USA, a study on educational intervention was conducted with 176 construction workers aiming to increase the use of HPDs.…”

“…Participants were 61 workers of both genders divided into intervention group (34 individuals) and control group (27 individuals). Comparison between pre-and post-intervention questionnaires showed significant difference in two of the ten themes addressed for the research group (27) . Comparison between groups regarding the mean scores of the responses to Questionnaire A according to gender (Table 3) showed statistically significant difference in five (13.88%) questions for the SG and in six (16.66%) questions for the CG.…”
