🔉 Did tinnitus loudness improve?
None shown.
Loudness/psychoacoustic effects inconsistent; 2020 meta-analysis found no significant effect on loudness measures.
rTMS (repetitive transcranial magnetic stimulation) for Tinnitus: What Does the Evidence Show?
Brain Stimulation · Ranked #10 on our Top 10 (weighting-sensitive)
Current evidence
Statistically real but clinically small — and whether any benefit lasts to 6 months is disputed between the major analyses.
Evidence strength: Limited (2/5) · Tier 3 — experimental/emerging · Evidence independence: Primarily independent.
Magnetic pulses applied over auditory/prefrontal cortex in clinic sessions, usually daily for 1–4 weeks. FDA-cleared TMS systems exist for depression/OCD; tinnitus use is off-label/investigational.
Did tinnitus loudness or distress improve?
🧠 Did tinnitus distress improve?
Limited.
Beats sham in the weeks after treatment (2025 meta-analysis of 16 RCTs: THI −11.5 immediately after treatment, from 11 studies and 739 people, and −11.0 at 1 month, from 3 studies). At 6 months the meta-analyses disagree: 2020 (29 RCTs) found a small significant effect (−6.5), 2025 found none (−4.3, not significant; 3 studies). Group averages are not directly comparable with the ~7-point THI change often cited as meaningful for an individual. Durability and protocol heterogeneity remain unresolved.
Loudness means the tinnitus percept itself became quieter (psychoacoustic matching or loudness ratings). Distress means questionnaire scores such as THI/TFI, sleep, anxiety or quality of life improved — the sound may be unchanged. A THI/TFI improvement is never evidence the tinnitus got quieter.
How strong is the evidence?
Many RCTs with short-term benefit over sham, but disputed durability, heterogeneous protocols and guideline advice against routine use: 2/5.

rTMS for tinnitus: meta-analysis of 16 RCTs
He Z, et al. · Frontiers in Neuroscience · 2025 · N=1,105 (16 RCTs) · Meta-analysis
Active rTMS beat sham post-treatment (THI MD −11.5) and at 1 month (−11.0). At 6 months the two big meta-analyses DISAGREE: this 2025 analysis found no significant effect (MD −4.26, 95% CI −10.28 to 1.76), while the 2020 meta-analysis (29 RCTs, N=1,228; PMID 33228598) found a small significant one (−6.53, 95% CI −11.41 to −1.66).
The 6-month estimates are small and uncertain in either meta-analysis; durability and magnitude are unresolved, not settled in either direction. The immediate estimate comes from 11 studies (739 people) and the 1-month estimate from 3 studies.
rTMS for chronic tinnitus: VA randomized sham-controlled trial (positive)
Folmer RL, et al. · JAMA Otolaryngology–Head & Neck Surgery · 2015 · N=70 randomized, 64 analyzed (32/arm) · Randomized placebo(coil)-controlled trial; 1-Hz rTMS × 10 consecutive workdays; NCT01104207
POSITIVE: responders 18/32 (56%) active vs 7/32 (22%) placebo, p<.005. Distress/severity outcome (TFI) — not loudness.
One half of the field's central contradiction: this positive trial coexists with the larger multicenter negative Landgrebe 2017 trial — which is why the platform labels rTMS replication 'Conflicting results'.
rTMS for chronic tinnitus: multicenter randomized sham-controlled trial (negative)
Landgrebe M, et al. · Brain Stimulation · 2017 · N=163 randomized (75 real / 78 sham) · Multicenter randomized sham-controlled trial; 1-Hz left temporal rTMS, 10 sessions; ISRCTN89848288
NEGATIVE: TQ change −0.5 (real) vs +0.5 (sham); adjusted difference −1.0 [95% CI −3.2, 1.2], p=0.36. Well tolerated; not superior to sham.
The largest multicenter rTMS tinnitus trial. Together with Folmer 2015 (positive), it defines the conflicting replication picture for rTMS.
AAO-HNSF Clinical Practice Guideline: Tinnitus
Tunkel DE, Bauer CA, Sun GH, et al. · Otolaryngology–Head and Neck Surgery · 2014 · N=Guideline (23-author multidisciplinary panel) · Clinical practice guideline (US)
RECOMMENDS: hearing-aid evaluation (with hearing loss) and CBT for persistent bothersome tinnitus. OPTION: sound therapy ('may recommend'). AGAINST routine use: medical therapy (antidepressants, anticonvulsants, anxiolytics, intratympanic drugs), dietary supplements (Ginkgo, melatonin, zinc), and rTMS. NO RECOMMENDATION: acupuncture.
Guidelines are consensus documents, not new trial data. Where the three major guidelines disagree — chiefly on sound therapy (AAO-HNSF: option; NICE and the European guideline: research-only; the German S3 guideline: against sound generators) — this platform shows the disagreement rather than picking a side. Statement strengths read from the published abstracts; full-text verbatim wording not independently re-read.
What are the limitations?
- 6-month durability disputed between meta-analyses; the 6-month estimates are small and uncertain
- Huge protocol heterogeneity
- Guideline recommends against routine use
Has the result been independently replicated?
Conflicting results. Independent replication attempted and discordant: Folmer 2015 positive vs Landgrebe 2017 multicenter negative; metas driven by heterogeneous small trials.
What should patients know about safety?
Safety evidence: Moderate. Generally safe; rare seizure risk; scalp discomfort and headache common.
Is it available?
Regulatory status: Investigational for tinnitus (off-label). No TMS system carries a tinnitus indication; AAO-HNSF 2014 recommends against routine TMS for tinnitus.
Availability: Off-label at some centers; research settings · Europe: Research + selected clinics · Cost (approx.): $200–400/session; courses $2,000–10,000, not covered
