The effect of a hearing conservation program on adolescents′ attitudes towards noise

Abstract

Crandell et al., reported that education programs such as hearing conservation programs (HCPs) represent the most common and well-recognized procedure in reducing the incidence of noise-induced hearing loss (NIHL). The purpose of this study was to assess the effectiveness of an HCP in changing knowledge and attitudes toward exposures to high intensity sounds or noise among adolescents aged 12-14 years. Local middle school students in physical education classes were recruited for participation. Sixty-four middle school students between the ages of 12 and 14 received pre- and post-test measures and participated in the HCP. The pre-test measure had 24 questions that included 5 demographic questions and 19 Likert-type questions [modified from the Youth Attitude to Noise Scale] that assess adolescents' attitudes towards noise; and a post-test measure included the identical 24 questions of the pre-test measure in addition to three subjective questions. A Wilcoxon signed rank test and a Two-Factor Analysis of Variance were completed to assess changes in knowledge and attitudes toward noise among the study population after receiving the HCP. A statistically significant reduction (P< 0.003) in pro-noise attitudes among the adolescents was present after the intervention. It was established that an HCP facilitated a change in pro-noise attitudes among adolescents. Further, the students thought this program facilitated learning of the auditory system and healthy hearing behaviors.
