Level 5 - mechanism / opinion, no new human data
Systematic review of heterogeneous literature noting a lack of randomized controlled trials
PubMed 32973991 · doi:10.1177/2040622320956426
What was done
The authors reviewed types and forms of sound therapy and the patient characteristics influencing curative effects in adult subjective tinnitus. Six databases, including PubMed, were searched using an established methodological framework, identifying 43 records that met predefined inclusion criteria.
What was found
The abstract reports no numerical outcomes, effect sizes, or statistical values. It qualitatively states that most sound therapy forms demonstrate positive therapeutic effects, customized sound therapy is generally more effective than non-customized therapy, and patients with more severe initial tinnitus show greater therapeutic response.
Why it matters
This review aggregates current acoustic management approaches, suggesting that tailored acoustic treatments outperform generic sounds for subjective tinnitus.
Limits
The abstract provides no quantitative metrics or meta-analytic data. The authors explicitly note a lack of randomized controlled trials, lack of unified tinnitus assessment criteria, and an absence of large, multicenter studies with long-term follow-up.
