Efectos de la exposición al ruido ocupacional en las áreas operativas de la Central Hidroeléctrica Manduriacu en el personal técnico.

Abstract

This study analyzed the effects of occupational noise exposure on technical personnel working in the operational areas of the Manduriacu Hydroelectric Power Plant. The research followed a mixed and descriptive approach, using a survey applied to 27 technical workers and a review of institutional documents related to noise monitoring, occupational medical examinations, risk assessment matrices, occupational health plans, and hearing protection records. The results showed that workers identify noise as a risk factor present during the workday. Turbines were reported as the main source of noise, while the most frequent symptoms were tinnitus, fatigue, difficulty concentrating, and headache. The 2025 occupational noise monitoring showed that exposure varies according to job position. Noise levels above the 85 dB(A) limit were identified in the Generation Unit Operator and Civil Infrastructure Maintenance Assistant positions. In addition, the reviewed audiometric reports showed previous hearing alterations in part of the evaluated personnel. It is concluded that occupational noise represents a relevant risk in the operational areas of the plant. Therefore, it is recommended to strengthen audiometric surveillance, proper use of hearing protection, equipment maintenance, signage in critical areas, and the evaluation of acoustic barriers as preventive measures.
