Audiologic characteristics in a sample of recently-separated military Veterans: The Noise Outcomes in Servicemembers Epidemiology Study (NOISE Study).Hearing research · 2017
- Documents high prevalence of audiometric abnormalities in recently separated veterans, often with normal pure-tone averages
- High-frequency hearing loss and abnormal otoacoustic emissions common despite 'normal' clinical hearing tests
- Establishes baseline audiologic profile of the post-9/11 veteran population
Why it matters: Supports claims by veterans whose VA C&P audiograms appear borderline-normal yet who exhibit high-frequency or supra-threshold deficits consistent with military noise exposure.

Prevalence of hearing loss and tinnitus in Iraq and Afghanistan Veterans: A Chronic Effects of Neurotrauma Consortium study.Hear Res · 2017
- Among Iraq/Afghanistan Veterans, 7.78% had hearing loss alone, 6.54% tinnitus alone, and 6.24% had both hearing loss and tinnitus.
- Comorbid TBI, PTSD, and depression were each significantly associated with increased rates of hearing loss, tinnitus, or both.
- Older individuals, males, and those with TBI, PTSD, or vertigo/dizziness were significantly more likely to have hearing loss.
Why it matters: Directly documents post-deployment hearing-loss prevalence and its clustering with TBI, PTSD, and tinnitus in the veteran population most relevant to DC 6100 service-connection.

Adult-onset hearing loss and incident cognitive impairment and dementia - A systematic review and meta-analysis of cohort studies.Ageing Res Rev · 2024
- Adult-onset hearing loss was associated with increased risk of incident dementia (HR 1.35), mild cognitive impairment (HR 1.29), and Alzheimer's disease dementia (HR 1.56).
- Each 10-decibel worsening of hearing was associated with a 16% increase in dementia risk, showing a dose-response relationship.
Why it matters: Establishes hearing loss as a dose-dependent risk factor for cognitive decline and dementia, a major secondary-condition and functional-impact consideration for DC 6100.

Association of hearing loss and risk of depression: a systematic review and meta-analysis.Front Neurol · 2024
- Hearing loss was associated with an increased risk of depression (OR 1.35), with older adults at higher risk (OR 1.33).
- The depression risk was higher in sudden sensorineural hearing loss (OR 1.62) than non-SSNHL and increased with follow-up of 5+ years.
Why it matters: Confirms hearing loss, including sensorineural subtypes, as an independent prospective risk factor for depression relevant to secondary mental-health claims under DC 6100.

A Hearing Intervention and Health-Related Quality of Life in Older Adults: A Secondary Analysis of the ACHIEVE Randomized Clinical Trial.JAMA Netw Open · 2024
- Over 3 years, a hearing intervention (hearing aids plus audiologic counseling) had no significant association with physical or mental health-related quality of life versus a health-education control.
- Differences were small and non-significant for both physical (0.43) and mental (0.47) HRQoL components.
Why it matters: Shows that even with treatment, hearing loss can persist in its impact on general quality of life, underscoring the durable functional burden of the condition relevant to DC 6100 severity assessment.
