Purpose: to validate the contents of an operating model of hearing conservation programs. Methods: this is a documentary and methodological research, in which the operating model was evaluated by ten experts in audiology, through the analysis of the activities developed in the implementation of the hearing conservation program. The components were analyzed according to the formula that determines the content validation index by item, and the operational logical model as a whole, according to the content validation formula by scale level. The items were considered valid when agreement among participants reached more than 80%. Results: the operating model was structured in 4 (four) dimensions, namely: (1) Management; (2) Environmental Control; (3) Attention to Hearing Health; (4) Evaluation of Efficacy and Efficiency. Each dimension corresponds to a set of activities (referred to as processes), and their respective results expected. For the structure of the program, considering its set of dimensions, material, organizational and human resources were listed. Conclusion: the proposed operating model and its components proved to be valid in their relevance and comprehensibility, offering support and applicability in evaluating the effectiveness and efficiency of the program.
