Guide of best practices in work's noise evaluations in Cuba. Minimal requirements

Abstract

Introduction: In Cuba it exists a system of Cuban norms of security and health in the work like instruments that standardize the mensuration methods and the approaches of evaluation of the noise in the positions and work areas, but it lacks a guide of good practical that allows the employment of the results of the evaluations like potentials tests for the scientific investigation of the factor of risk.

Objective: To propose the minimum requirements for a guide of good practical in the study of the factor of risk labor noise.

Methods: A process of consent search is developed among experts, through the technique of the four processes of resolution of problems to propose the minimum requirements that should be considered in the evaluations of labor noise.

Results: The necessary minimum requirements settled down in the studies of noise respecting the normative ones national, what was structured in the following elements: glossary of terms, mensuration methods for the objective that is pursued, approaches of evaluation of the noise, mensuration methods for the type of work position (positions of fixed works, variables and aleatory), purpose of the evaluations, requirements metrological, utility of the map of noise and informative requirements.

Conclusions: The elaborated guide proposes methodological improvements inside the experimental investigation of the labor noise, she doesn't force but alone it recommends an investigative strategy, it gives space to the personal interpretations and references elaborated as truths hypothetical, those that can impact in new methodological and normative proposals to future
