Summary
Auditory training, including frequency discrimination and attentional skills, shows significant benefits for tinnitus treatment in adults. Recent studies with higher evidence levels incorporate attentional factors and multisensory pathways.
Area of Science:
- Audiology
- Neuroscience
- Evidence-Based Medicine
Background:
- Tinnitus is a prevalent condition affecting adults and older adults.
- Auditory training is an audiological treatment approach for tinnitus.
- The evidence base for auditory training in tinnitus requires verification.
Purpose of the Study:
- To verify the evidence supporting auditory training in the audiological treatment of tinnitus.
- To assess the quality of evidence for different auditory training strategies.
Main Methods:
- A scoping review was conducted using major databases (PubMed, Embase, LILACS, Cochrane Library).
- Peer assessment of titles and abstracts followed by full-text review and reference searching.
- Studies' level of evidence was classified using the Critically Appraised Topics (CATs) scale.
Main Results:
- 15 studies were eligible from 2160 initial records.
- Frequency discrimination training was the most common strategy.
- Most studies reported significant benefits, with evidence levels ranging from limited to high (C–A), particularly for attentional and multisensory approaches.
Conclusions:
- Recent auditory training strategies demonstrate higher levels of evidence.
- Attentional factors and multisensory pathways are increasingly integrated into effective tinnitus auditory training.
