Abstract
In 2011, over 520 thousand persons worked in hazardous conditions
(according to the GUS). Among hazardous factors related to working
environment noise was found to be the most common one, threatening 199,6
thousand people (52.9% threats-per-persons related to working
environment). The prevalence of workplace noise and increasing awareness
of effects of its impact on the human body causes increase of the demand
for knowledge of the methods of noise reduction. Due to the lack of
knowledge concerning the proper use of hearing protectors, effective noise
exposure in the real world may be about a dozen dB higher than the
declared assumed protection value. For this reason, in Central Institute
for Labour Protection - NRI “The interactive system for learning the
correct use of hearing protectors” has been developed. The system includes
a multimedia guide on hearing protectors supplemented by video tutorials,
training materials with training hearing protectors, and software for
evaluation of the activities of the trainee.
