Prevalence of Unilateral, Asymmetric, and Bilateral Tinnitus in Military Personnel and Its Impact on Disability.Otolaryngology--head and neck surgery : official journal of American Academy of Otolaryngology-Head and Neck Surgery · 2025
- Quantifies the prevalence of unilateral, asymmetric, and bilateral tinnitus in active and former military
- Bilateral tinnitus is associated with greater functional disability

Continuous Improvement of Chronic Tinnitus Through a 9-Month Smartphone-Based Cognitive Behavioral Therapy: Randomized Controlled Trial.J Med Internet Res · 2025
- Smartphone-based CBT significantly reduced Tinnitus Questionnaire scores (by 12.5 points at 3 months and 18.5 at 9 months; Cohen d 1.38).
- Depression (PHQ-9) and perceived stress (PSQ-20) also improved significantly.
- The waiting-list control showed no change until app-based CBT commenced.
Provides RCT evidence that scalable CBT can meaningfully reduce chronic tinnitus burden, while confirming tinnitus is a chronic condition requiring sustained management.

Associations Between Physiological Correlates of Cochlear Synaptopathy and Tinnitus in a Veteran Population.Journal of speech, language, and hearing research : JSLHR · 2023
- Reduced auditory-nerve responses (consistent with cochlear synaptopathy) are associated with tinnitus in veterans with normal audiograms
- Provides physiological evidence for noise-induced 'hidden hearing loss' contributing to tinnitus
- Supports plausibility of service-connected tinnitus even with normal hearing thresholds
Critical evidence for VA claims where veteran reports tinnitus despite normal audiograms; supports the cochlear-synaptopathy mechanism linking military noise exposure to tinnitus under DC 6260.

The Interrelationship of Tinnitus and Hearing Loss Secondary to Age, Noise Exposure, and Traumatic Brain Injury.Ear and hearing · 2022
- Using Million Veteran Program data, demonstrates strong co-dependence of tinnitus and hearing loss
- TBI is an independent contributor to tinnitus risk beyond noise and age
- Supports causal pathways linking military service exposures to chronic tinnitus
Provides VA-specific Million Veteran Program evidence that veterans can cite to support secondary-service-connection claims for tinnitus arising from noise exposure, TBI, or hearing loss.

Global Prevalence and Incidence of Tinnitus: A Systematic Review and Meta-analysis.JAMA Neurol · 2022
- Pooled prevalence of any tinnitus among adults was 14.4% (95% CI 12.6-16.5%), rising with age to 23.6% in those aged 65+.
- Pooled prevalence of severe tinnitus was 2.3% and of chronic tinnitus 9.8%; pooled incidence was 1,164 per 100,000 person-years.
- Authors estimate tinnitus affects more than 740 million adults globally and is a major problem for over 120 million.
Establishes the high baseline population prevalence and incidence of tinnitus, grounding the plausibility and commonness of DC 6260 claims.

Cognitive behavioural therapy for tinnitus.Cochrane Database Syst Rev · 2020
- Cognitive behavioural therapy may reduce the impact of tinnitus on quality of life at treatment end (THI ~11 points lower vs no intervention, exceeding the 7-point MCID).
- CBT may produce a slight reduction in depression; serious adverse effects were rare.
- There was an absence of evidence at 6- and 12-month follow-up, so durability is uncertain.
Best available evidence that even the guideline-recommended treatment yields only modest, mainly short-term symptom relief, supporting that tinnitus typically persists despite treatment.

Natural history of tinnitus in adults: a cross-sectional and longitudinal analysis.BMJ Open · 2020
- 17.7% reported tinnitus and 5.8% bothersome tinnitus; the 4-year incidence of tinnitus was 8.7%.
- Age, hearing difficulties, work noise exposure, ototoxic medication, and neuroticism were positively associated with tinnitus.
- At 4-year follow-up only 18.3% of those with tinnitus reported resolution, with worsening and improvement equally likely; tinnitus is largely persistent.
Provides large longitudinal evidence that tinnitus rarely resolves and that occupational noise is a risk factor, supporting the chronic, persistent nature of DC 6260.

Impact of TBI, PTSD, and Hearing Loss on Tinnitus Progression in a US Marine CohortMilitary medicine · 2019
- Pre-deployment TBI and PTSD each independently increase odds of new or worsening tinnitus post-deployment
- Hearing loss strongly predicts tinnitus progression in Marines
- Combat deployment is associated with measurable worsening of tinnitus symptoms
Useful for veterans filing secondary tinnitus claims connected to TBI or PTSD; demonstrates that combat service measurably worsens tinnitus.

Impact of Tinnitus on Military Service Members.Mil Med · 2019
- Tinnitus had measurable effects on job performance, concentration, anxiety, depression, and sleep in both active and post-military samples.
- Tinnitus impact on active-duty Service members was comparable to its impact on recently-separated Veterans.
Demonstrates that tinnitus produces functional and psychosocial impairment beginning during active service, supporting in-service onset and occupational impact for DC 6260.
