Occupational Hearing Loss Under N.C.G.S. § 97-61.5

Occupational noise-induced hearing loss is the most common occupational disease claim in North Carolina. It affects workers across manufacturing, construction, transportation, textile production, and any other industry involving sustained exposure to noise levels at or above OSHA’s permissible exposure limit of 90 dBA as an 8-hour time-weighted average, or 85 dBA under the OSHA action level triggering a mandatory hearing conservation program.

N.C.G.S. § 97-61.5 governs occupational hearing loss claims in NC workers’ comp. The statute creates a specific framework that differs from other occupational disease claims:

• Scheduled disease status — Occupational hearing loss is a listed scheduled disease under § 97-53(28), meaning it is presumed compensable when a qualifying causal relationship to workplace noise is established.
• 90-day waiting period — The claimant must have been removed from the noise exposure for at least 90 days before the permanency evaluation audiogram is performed. This period allows temporary threshold shifts (noise-induced fatigue) to resolve and ensures the evaluation captures permanent threshold shift — the compensable component.
• Compensation formula — Total bilateral hearing loss is compensated at 150 weeks of benefits. Partial losses are compensated proportionally based on the audiometrically determined percentage of hearing loss, after adjusting for the age-related presbycusis component.

The employer and its workers’ comp insurer are required to provide the permanency evaluation audiogram through a qualified ENT or audiologist. If the employer’s evaluation underestimates the hearing loss — a common insurer tactic — an independent audiologic evaluation obtained by the claimant’s attorney is submitted to the Industrial Commission for comparison.

OSHA Noise Standards and Workplace Exposure Documentation

OSHA’s noise standard at 29 C.F.R. § 1910.95 requires employers to implement a hearing conservation program when employee noise exposures equal or exceed 85 dBA as an 8-hour time-weighted average. This program includes annual audiometric testing, noise dosimetry measurements, and hearing protection provision. These employer records are the primary objective evidence in occupational hearing loss claims.

Key OSHA documentation pursued in every hearing loss claim:

• Noise dosimetry and area monitoring records — OSHA requires employers to maintain workplace noise measurement records for at least two years. These records document the actual noise levels in each work area and establish whether the exposure levels could cause occupational hearing loss.
• Audiometric testing records — Annual baseline and periodic audiograms performed under the employer’s hearing conservation program create a longitudinal record of threshold shifts over the course of employment. These records document when the hearing loss developed and how it progressed.
• Hearing conservation program records — Records of hearing protection provision, training completion, and hearing protector fit testing document whether the employer implemented an adequate program and whether the claimant’s exposure was effectively controlled.
• Material safety data sheets and equipment specs — In industrial settings, the noise output specifications of specific machines used by the claimant, combined with the production schedule and shift records, establish the intensity and duration of the noise dose.

These records are subject to OSHA’s two-year retention requirement for noise dosimetry and longer retention requirements for audiometric records. However, employers that have gone out of business, been acquired, or restructured may not have preserved these records. Cameron Bauer initiates preservation demands to all potentially responsible employers as soon as case intake is complete.

The Permanency Evaluation and Rating Methodology

The permanency evaluation is the decisive step in an NC occupational hearing loss workers’ comp claim. An otolaryngologist or certified audiologist measures pure-tone thresholds at 500, 1000, 2000, and 3000 Hz in each ear, calculates the monaural percent impairment for each ear using the American Academy of Otolaryngology formula, and then calculates the binaural hearing impairment. The binaural percentage is applied to the 150-week statutory maximum to determine weeks of compensation.

The presbycusis adjustment is one of the most contested aspects of hearing loss ratings. Presbycusis — age-related hearing loss — affects everyone and creates low-frequency and high-frequency threshold shifts that are not occupationally caused. NC workers’ comp allows a presbycusis offset based on age and the expected age-related hearing loss at each audiometric frequency. Employers and insurers routinely argue for aggressive presbycusis offsets to reduce the compensable percentage; claimants’ physicians argue for conservative adjustments that protect the full occupational component.

When the employer’s rating and the claimant’s independent rating conflict, the NC Industrial Commission resolves the dispute through a hearing at which both audiometric experts testify. Cameron Bauer retains independent ENT experts with specific NC Industrial Commission testimony experience for all contested rating disputes.

Occupational Hearing Loss Compensation and Treatment

NC workers’ comp provides two categories of benefits for occupational hearing loss: the permanency award calculated from the audiometric rating, and ongoing medical treatment for the hearing loss and any related conditions. The permanency award is a lump-sum or structured payment based on the percentage of hearing loss applied to the 150-week schedule. Medical benefits cover hearing aids, audiologic follow-up, and treatment for related tinnitus.

Tinnitus (ringing in the ears) frequently accompanies noise-induced hearing loss and is itself a compensable occupational disease under § 97-53 when causally linked to workplace noise exposure. The tinnitus disability is rated separately from the pure audiometric hearing loss and may add additional weeks of compensation to the award.

Hearing aids prescribed as a result of occupational hearing loss are a medical benefit the employer and insurer must provide. The employer’s obligation extends to the ongoing cost of hearing aid batteries, repairs, and replacement — not just the initial fitting. Cameron Bauer ensures the medical treatment component of every hearing loss claim addresses the long-term hearing aid and audiologic care needs.
