Desenvolvimento de uma metodologia para a inclusão dos deficientes auditivos em um ambiente industrial logístico

Abstract

This research aims to develop a methodology for the industrial logistics sector, aimed at promoting the safe and efficient inclusion of hearing-impaired workers in production processes involving human-machine interaction. The investigation begins by analyzing operational flows and identifying the main challenges related to safety, ergonomics, and risk perception in environments with automated equipment. The adopted methodological approach includes four complementary stages: (i) administering an exploratory questionnaire to hearing-impaired workers and the machine operators with whom they interact; (ii) analyzing the responses obtained and identifying the need for further exploration of risk perception; (iii) developing and validating a specific instrument for measuring risk perception, supported by audiovisual recordings of work activities; and (iv) conducting practical tests with assistive devices provided by three different companies, with the aim of evaluating their effectiveness and safety in the joint operational routine between operators and hearing-impaired workers. The study was conducted at a large logistics company, directly involving hearing-impaired professionals involved in production activities involving mechanical interaction. The results showed that, although there is potential for full inclusion, currently available assistive devices have technical and functional limitations, as they were not originally designed to meet the specific needs of this population. These findings reinforce the need for technological and methodological improvements to ensure equity, autonomy, and safety for these workers in industrial settings. The research thus contributes to the advancement of inclusive practices in the production sector, providing support for the development of operational adaptations, and more effective assistive solutions.
