L’adattamento protesico ha l’obiettivo di garantire al paziente ipoacusico una percezione sonora equilibrata, rispettando la dinamica uditiva residua. Questa tesi analizza il ruolo della dinamica residua nel fitting protesico, approfondendo sia gli aspetti teorici sia le applicazioni cliniche. Dopo una revisione dei concetti fondamentali di soglia uditiva, MCL e UCL, vengono presentati i principali algoritmi prescrittivi utilizzati nell’adattamento (tra cui NAL-NL2 e DSL), con attenzione ai criteri di scelta e ai limiti applicativi. La verifica dell’efficacia del fitting viene affrontata attraverso le Real Ear Measurements (REM), che consentono di valutare in vivo la risposta dell’apparecchio acustico rispetto al campo dinamico del paziente. Lo studio integra i dati della letteratura con osservazioni pratiche, sottolineando l’importanza di un approccio personalizzato che combini algoritmi prescrittivi e verifica strumentale per ottimizzare i risultati clinici.

Abstract
The goal of hearing aid fitting is to provide hearing-impaired patients with a balanced auditory perception while respecting their residual dynamic range. This thesis analyzes the role of the residual dynamic range in hearing aid fitting, addressing both theoretical aspects and clinical applications. After reviewing the fundamental concepts of hearing threshold, MCL, and UCL, the study presents the main prescriptive algorithms used in fitting (including NAL-NL2 and DSL), focusing on selection criteria and limitations. The effectiveness of the fitting is assessed through Real Ear Measurements (REM), which allow in vivo evaluation of the hearing aid response in relation to the patient’s dynamic range. The work combines evidence from the scientific literature with practical observations, highlighting the importance of a personalized approach that integrates prescriptive algorithms and instrumental verification to optimize clinical outcomes.| File | Dimensione | Formato | |
