Impact of Smart Hearing Aid Technology on Self-Esteem in Patients with Sensorineural Hearing Loss: A Cross-Sectional Multivariate Study

Background: Sensorineural hearing loss represents a significant global health burden affecting over 1.5 billion individuals worldwide. Modern hearing aids, equipped with digital signal processing and smart connectivity features, constitute a cornerstone of neuro-sensory rehabilitation. However, the psychosocial impact of these assistive smart technologies on patient self-esteem remains incompletely characterized. Methods: A cross-sectional multivariate study was conducted with 245 participants, divided into three groups: normal-hearing controls (NH, n = 73), hearing-impaired patients using smart hearing aid technology (HA users, n = 86), and hearing-impaired patients not using hearing aid technology (HA non-users, n = 86). Self-esteem was measured using the Rosenberg Self-Esteem Scale (SES). Hearing disability and tinnitus severity were assessed with the Hearing Handicap Inventory for Adults (HHIA) and Tinnitus Handicap Inventory (THI), respectively. Data analysis included one-way ANOVA, Tukey’s HSD post hoc tests, Pearson correlations, and multivariate regression. Results: Hearing aid users showed significantly higher SES scores (35.41 ± 5.32) compared to non-users (22.99 ± 4.53; p < 0.001, Cohen’s d = 2.515). One-way ANOVA indicated highly significant differences among groups (F = 299.00, p < 0.001, η2 = 0.712). SES was negatively correlated with HHIA (r = −0.573, p < 0.001) and THI (r = −0.443, p < 0.001), while HHIA and THI were strongly positively correlated (r = 0.729, p < 0.001). In multivariate analysis, HA use remained a strong independent predictor of self-esteem (β ≈ 11.9, p < 0.001), even after adjustment for age, sex, HHIA, and THI. Perceived hearing handicap was independently associated with lower self-esteem, whereas tinnitus severity was not a significant predictor in the fully adjusted model. The model explained approximately 65% of the variance in self-esteem scores. Conclusions: Smart hearing-aid use is strongly and independently associated with higher self-esteem in patients with sensorineural hearing loss. These results support the inclusion of modern audiological rehabilitation devices in comprehensive management strategies for long-term conditions and highlight psychosocial benefits that extend beyond hearing restoration.
