RESUMO

Introduction: The hearing aid verification stage has been studied over many years by different protocols and equipments to increase de user satisfaction. Objective: design a hearing aid protocol using Visible Speech Mapping applied to clinical practice in order to analyze the user satisfaction. Method: The cross-sectional, randomized study was done with 60 adults, separated into two groups without prior amplification experience binaurally fitted with digital behind-the-ear hearing aid technology. Four weeks later, the group A answered Protocol IIIA covering insertion gain, Word recognition test, Visible Seech Mapping verification tool without counseling, Client Oriented Scale of Improvement and Satisfation with Amplification in Daily Life questionnaires. The group B was evaluated using the Protocol IIIB containing Word Recognition Test, Visible Speech Mapping verification and counseling tool, Client Oriented Scale of Improvement and Satisfation with Amplification in Daily Life questionnaries. Results: The results showed moderated correlation between insertion gain and Visible Speech Mapping analyzing the procedures when applied to the group A. When Visible Speech Mapping register a soft, medium and strong stimulus within de dynamic range, each 10% improvement at the Word Recognition Test´s result means a 0.4 to 0.5 points, at silence, and 0.2 a 0.3 points increase at speech-in- noise on the satisfaction global score. Conclusions: digital hearing aid verification protocol using Visible Speech Mapping has demonstrated to be effective to the clinical practice.
