Mississippi is home to one of the most significant shipbuilding operations in the United States. A major shipbuilding facility in Pascagoula is the nation's largest builder of surface combatant vessels and employs approximately 11,000 workers in an extremely high-noise manufacturing environment. Add Camp Shelby, Keesler AFB, Columbus AFB, significant agricultural processing, and a growing automotive sector, and Mississippi's occupational hearing loss exposure is substantial. Soundtrace helps Mississippi employers build and maintain exactly that program — so when a claim arrives, the records are already there.
Governing statute: Mississippi Workers' Compensation Act, Miss. Code Ann. §71-3-1 et seq.
Administering body: Mississippi Workers' Compensation Commission (MWCC)
Filing deadline: 2 years from date of injury; occupational disease: 2 years from disability or last injurious exposure
Compensation basis: Scheduled permanent partial disability: §71-3-17; total bilateral hearing loss: 100 weeks
Notable: Many shipbuilding workers in Pascagoula are covered under LHWCA (federal), not Mississippi state WC

Noise-induced hearing loss (NIHL) is classified as an occupational disease in Mississippi. A critical first step in any Mississippi shipbuilding claim is determining whether the worker is covered under state WC or the federal LHWCA.
The critical first step in any Mississippi shipbuilding hearing loss claim is determining whether the worker is covered under Mississippi state WC or the federal LHWCA. The two systems have different benefit levels, different procedures, and different courts. Mississippi employers in maritime industries should have counsel make this coverage determination at the outset of any claim.
Worker exposed at Mississippi facility. Federal OSHA 1910.95 applies; LHWCA may apply to shipbuilding workers.
NIHL accumulates over years. Pascagoula shipbuilding workers face extreme noise from steel cutting, welding, and systems installation.
Critical: shipbuilding workers performing maritime work are typically covered under the federal LHWCA, not Mississippi state WC. Coverage determination must be made at the outset of each claim.
State WC: filed with MWCC. LHWCA: filed with U.S. Department of Labor, Office of Workers' Compensation Programs (OWCP).
IME with ANSI-compliant audiometry. Mississippi state WC uses scheduled loss under §71-3-17.
MWCC Administrative Judge issues scheduled loss award for state WC claims.
Occupational hearing loss compensation in Mississippi is calculated based on the degree of binaural hearing impairment. Verify current benefit rates with the Mississippi MWCC or qualified workers' compensation counsel.
| Loss Type | Benefit Basis | Notes |
|---|---|---|
| Total loss, one ear | 50 weeks at 66⅔% AWW | Subject to state maximum weekly rate |
| Total loss, both ears | 100 weeks at 66⅔% AWW | Binaural formula applied; proportionate for partial |
| Partial loss | % of 100 weeks | Proportionate to degree of binaural loss |
| Medical benefits | Reasonable & necessary | Includes audiological care, hearing aids |
The Lancet Commission (2024) identified hearing loss as the single largest modifiable risk factor for dementia — a 37% increased risk of incident dementia across six cohort studies.
The ACHIEVE Trial (Johns Hopkins / The Lancet, 2023) found that hearing intervention slowed cognitive decline by 48% over three years. Dr. Frank Lin: "Hearing loss is arguably the single largest risk factor for dementia."
Why this matters for Mississippi employers: Workers exposed to occupational noise carry a hearing loss burden that won't fully materialize in claims for another 10–30 years. This is precisely the problem Soundtrace was built to solve.
| Research Finding | Source | Implication for MS Employers |
|---|---|---|
| 37% increased dementia risk from hearing loss | Lancet Commission 2024 | Workers with occupational NIHL face elevated downstream dementia and disability risk |
| 48% reduction in cognitive decline with intervention | ACHIEVE Trial, Johns Hopkins, 2023 | Early treatment through HCP programs reduces total health and disability costs |
| 7% of dementia cases potentially preventable | Lancet Commission 2024 | Significant preventable dementia burden among Mississippi's industrial workforce |
| 19% reduction in cognitive decline with hearing aids | Australian Longitudinal Study, 2024 | Employers enabling early treatment reduce long-term worker health costs |
| Hearing loss linked to cardiovascular disease, depression | Multiple studies, 2020–2025 | Co-morbid conditions add to total claims exposure over time |
The most effective thing a Mississippi employer can do is maintain a complete, documented hearing conservation program. Soundtrace provides the infrastructure: in-house audiometric testing, automated STS detection, digital record retention, HPD fit testing, and professional audiology oversight.
Soundtrace provides in-house audiometric testing, automated STS detection, digital record retention with full audit trails, and professional audiology oversight — giving Mississippi employers the documented hearing conservation program they need to defend against occupational hearing loss claims.
Workers performing 'maritime employment' on the 'navigable waters of the United States or adjoining areas' are generally covered under the federal LHWCA rather than state workers' compensation. Pascagoula shipbuilding workers typically qualify as maritime workers covered under LHWCA. This means LHWCA benefits, LHWCA procedures (Department of Labor), and LHWCA courts apply — not Mississippi MWCC. Employers with shipbuilding operations should consult maritime WC counsel for specific coverage analysis.
The LHWCA provides federal workers' compensation for maritime workers and generally provides higher benefits than most state WC systems. LHWCA claims are filed with the U.S. Department of Labor, adjudicated by ALJs in the Office of Workers' Compensation Programs, and appealable to the Benefits Review Board. Mississippi employers with maritime operations face a federal — not state — compensation framework for most of their shipbuilding workforce.
The major automotive assembly plant in Blue Springs (Pontotoc County) produces the Corolla and employs approximately 2,000 workers. Automotive stamping, welding, painting, and assembly generate significant noise exposure. Workers at this facility are covered under Mississippi state WC. Mississippi automotive employers should maintain OSHA 1910.95-compliant hearing conservation programs and complete annual audiometric testing records.
Mississippi schedules total bilateral hearing loss at 100 weeks at 66⅔% AWW — lower than most Northern industrial states (Illinois: 215 weeks; Pennsylvania: 260 weeks) but comparable to some Southern states. The underlying noise exposure from the major shipbuilding facility, poultry processing, and military operations remains significant regardless of benefit levels.
Soundtrace gives Mississippi employers in-house audiometric testing, automated STS tracking, HPD fit testing, and audit-ready records — everything needed to protect your workforce and defend your position when a claim arrives.
