This cross-sectional observational study analyzed data from routine clinical practice to compare outcomes across independent treatment duration cohorts (3, 6, and 9 months).

Cross-sectional design prevents causal conclusions, but findings suggest longer sound therapy exposure correlates with better tinnitus outcomes — audiologists should note this as hypothesis-generating, not yet a basis to extend treatment protocols without further controlled evidence.

Understanding the dose-response relationship between sound therapy duration and tinnitus relief is clinically important for counselling patients on realistic treatment timelines.
