Hearing claims are decided on evidence, and the evidence that matters is more specific than most veterans expect. This guide covers what strengthens a file, what undermines one, and where an independent medical opinion fits. For the regulatory framework, start with our tinnitus service connection overview.
1. Evidence of the current condition
For hearing loss, this means an audiological examination meeting the requirements of 38 CFR 4.85 - puretone audiometry plus a Maryland CNC speech discrimination test, performed by a state-licensed audiologist. For tinnitus, the veteran's own consistent report is competent evidence, because the sound is perceptible only to the person experiencing it. Consistency across statements and treatment notes is what gives that report weight.
2. Evidence of in-service noise exposure
The strongest files identify the exposure concretely rather than generally:
- Duty assignment and military occupational specialty, with the equipment and environment involved
- Deployment and training records placing you around weapons, aircraft, engines, or generators
- Hearing conservation program enrollment or issued hearing protection
- Entrance and separation audiograms, compared for any threshold shift
- Any documented acoustic trauma event - a blast, an explosion, a head injury
3. The audiogram comparison
A shift between entrance and separation testing, even one that stays within the normal range, is objective evidence that hearing changed during service. It is frequently overlooked because both tests read as normal in isolation. Pulling those two audiograms side by side is one of the most useful things that can be done with a service record.
4. Continuity after service
Evidence of what happened after separation matters when the diagnosis came years later: when the symptoms were first mentioned to a provider, what treatment or devices were tried, and whether the condition progressed. Gaps are not fatal, but an account that explains them is more persuasive than one that does not.
Where veterans start
Every case is different, and there is no obligation at any step. When veterans want to understand what their records actually support, these are the two most common starting points:
- Medical records review
A licensed physician reviews your records for a $250 flat fee and identifies which conditions the available evidence may support. The fee is refunded in full if nothing supportable is identified.
- Nexus letter
When the records support one, a licensed provider writes the medical opinion addressing the link between your hearing condition and your service, including delayed-onset reasoning where that applies.
5. Lay statements from people who observed it
A spouse, coworker, or fellow service member can state what they personally observed - the television volume, asking for repetition, difficulty in crowded rooms, complaints about ringing that began during or shortly after service. The useful statements are concrete and dated. Vague generalities add nothing.
6. A reasoned medical opinion
Where the contested point is the link to service, a written opinion can address it. A probative opinion identifies the records reviewed, describes the exposure, explains the medical mechanism including delayed-onset reasoning where it applies, engages with a normal separation audiogram rather than ignoring it, addresses civilian noise exposure and other alternative causes, and states its conclusion in the VA's own terms - see our guide to at least as likely as not.
The weaknesses that most often lead to a denial
In practice, the same problems appear repeatedly:
- No identified in-service noise exposure beyond a general assertion
- Entrance and separation audiograms never compared
- An examination that omits the required speech discrimination test
- An inconsistent account of when the symptoms began
- An opinion that states a conclusion without medical reasoning
- An opinion that never addresses the normal separation audiogram the denial relied on
Where to start
The first step is knowing what your file already shows. A paid medical records review is $250, and a licensed physician identifies which conditions the available evidence may support - including the audiogram comparison - before anything further is ordered. The fee is refunded in full if nothing supportable is identified. Where the records support a medical opinion, a nexus letter supplies it.
Talking through your situation by phone is always free, and there is never any obligation. Patriot NEXUS Letters provides independent medical evidence, not legal representation or claim filing. We do not guarantee that a medical professional will reach a favorable conclusion or that the VA will approve any claim.
