Wyoming has the most intensive coal mining economy of any state in the US. The Powder River Basin in northeastern Wyoming produces more coal than any other region in the world, with massive surface mining operations near Gillette. Wyoming also has significant trona mining near Green River (world's largest trona deposits), oil and gas production, and a military presence at FE Warren AFB. Wyoming is a monopolistic state fund — all employers must insure through the state fund with no private WC carriers. Soundtrace helps Wyoming employers build and maintain exactly that program — so when a claim arrives, the records are already there.
Governing statute: Wyoming Workers' Compensation Act, Wyo. Stat. §27-14-101 et seq.
Administering body: Wyoming Department of Workforce Services, Workers' Compensation Division
Filing deadline: 1 year from date of last injurious exposure — one of the shortest in the US
Compensation basis: Permanent partial impairment (PPI) benefits based on AMA Guides impairment rating
Notable: Wyoming is a monopolistic state fund — all employers must insure through the state fund; 1-year SOL for occupational disease is among the shortest in the US

Wyoming workers in several sectors routinely face noise at or above the 85 dBA OSHA action level:
Source: NIOSH Industry & Occupation Noise Exposure data. Figures represent sector-level averages; actual exposure varies by facility and job role.
Under OSHA 29 CFR 1910.95 (federal OSHA applies; Wyoming does not have a state OSHA plan; MSHA applies to mining), any employer with workers exposed at or above 85 dBA TWA must implement a hearing conservation program. These requirements are also the exact documentation steps that create the employer's best legal defense.
Soundtrace was built to handle every element of OSHA 1910.95 compliance — in-house audiometric testing, automated STS detection, HPD fit testing, and digital recordkeeping with a full audit trail. Wyoming employers who use Soundtrace arrive at a claim with organized, complete records rather than scrambling to reconstruct them.
Noise-induced hearing loss (NIHL) is classified as an occupational disease in Wyoming. Understanding how claims work helps employers build documentation before a claim arrives — not after.
Wyoming's occupational disease SOL is only 1 year from the date of last injurious exposure — one of the shortest in the US. For noise-induced hearing loss, this means the filing window closes very quickly after a worker's last significant noise exposure. Wyoming employers who conduct annual audiometric testing and notify workers of significant threshold shifts should document those notifications carefully, as this may affect when the SOL clock begins.
Worker exposed at Wyoming facility. Federal OSHA 1910.95 applies; MSHA applies to mining.
NIHL accumulates over years. Wyoming coal and trona mining workers face extreme sustained noise levels.
Wyoming's 1-year SOL for occupational disease is one of the shortest in the US.
Worker files claim directly with Wyoming's monopolistic state fund within 1 year.
State fund physician or IME performs ANSI-compliant audiometry. Wyoming uses AMA Guides for PPI ratings.
Disputed claims heard by Office of Administrative Hearings (OAH). Decisions appealable to district court.
Workers' compensation statutes were written before landmark research changed how medicine understands hearing loss. Today's claims picture is just the beginning.
The Lancet Commission (2024) identified hearing loss as the single largest modifiable risk factor for dementia — a meta-analysis of six cohort studies found a 37% increased risk of incident dementia attributable to hearing loss.
The ACHIEVE Trial (Johns Hopkins / The Lancet, 2023) found that hearing intervention slowed cognitive decline by 48% over three years in higher-risk adults. Dr. Frank Lin: “After a decade of epidemiological research, we knew hearing loss is arguably the single largest risk factor for dementia.”
Why this matters for Wyoming employers: Workers exposed to occupational noise over the past two to three decades are carrying a hearing loss burden that won't fully materialize in claims for another 10–30 years. The employers who build defensible, documented programs today are the ones who will have both a healthier workforce and a defensible record when that wave arrives. This is precisely the problem Soundtrace was built to solve.
| Research Finding | Source | Implication for WY 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 / The Lancet, 2023 | Early treatment through HCP programs reduces total long-term health costs |
| 7% of dementia cases potentially preventable | Lancet Commission 2024 | Significant preventable burden in Wyoming's industrial workforce |
| 19% reduction in cognitive decline with hearing aids | Australian Longitudinal Study, 2024 | Employers enabling early treatment reduce total worker health costs over time |
| Hearing loss linked to cardiovascular disease, depression | Multiple peer-reviewed studies, 2020–2025 | Co-morbid conditions increase total claims exposure beyond hearing loss alone |
The most effective thing a Wyoming employer can do — for worker health and for legal protection — is maintain a complete, documented hearing conservation program. Soundtrace provides Wyoming employers with the infrastructure to do exactly this: in-house audiometric testing, automated STS detection, digital record retention, HPD fit testing, and professional audiology oversight, all in one platform.
The Powder River Basin in northeastern Wyoming produces more coal than any other region in the world. Surface mining operations at massive mines near Gillette — some of the largest surface mines on earth — involve haul trucks (100–105 dBA at operator), draglines, shovels, and coal processing plants generating extreme sustained noise. Wyoming coal employers must comply with MSHA hearing conservation requirements AND maintain Wyoming WC audiometric documentation.
Wyoming is one of four states (along with Ohio, Washington, and North Dakota) with a monopolistic state workers' compensation fund. All Wyoming employers must insure through the state fund — there are no private WC carriers. All premium payments, claims, and disputes go through the Wyoming Department of Workforce Services.
The Green River Basin contains the world's largest known trona deposits. Trona mining involves underground and solution mining operations with crushers, conveyors, dryers, and refining equipment generating significant noise exposure. Trona mining employers must comply with MSHA hearing conservation requirements and maintain separate Wyoming WC audiometric documentation for all workers exposed at or above 85 dBA TWA.
Francis E. Warren AFB in Cheyenne is headquarters for the 90th Missile Wing, responsible for Minuteman III ICBM operations. Federal employees at Warren are covered under FECA, not Wyoming state WC. Private defense contractors at Warren AFB are covered under Wyoming state WC and should maintain OSHA 1910.95-compliant hearing conservation programs for all noise-exposed contract workers.
Soundtrace gives Wyoming 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.
