Abstract

A before-after controlled clinical trial was conducted on 200 new recruits from the Armored Tank Corps. The intervention group of 100 recruits was trained to provide knowledge about occupational deafness, the harmful effects of noise on the auditory organs, and measures to prevent noise. In addition, the recruits were also trained in the use of standard noise-canceling helmets of the Armored Tank Army. The control group consisted of 100 recruits who did not participate in the training. The results showed that, before intervention, 28% of recruits in the intervention group knew that occupational deafness could not be treated. After the intervention, this number increased to 64%. The intervention efficiency was 92.16%, higher than the control group with a statistically significant difference (p<0.05). After training, on how to properly use ear caps to prevent noise, the effectiveness in the intervention group was 17.24% with p<0.05.
