Occupational Noise Exposure and Hearing Protection in Wilmington & Southport, NC

Noise-induced hearing loss is the most common occupational injury in the United States. An estimated 22 million workers are exposed to potentially damaging noise levels each year — in industries ranging from construction and manufacturing to agriculture, military, law enforcement, and more. The damage caused by occupational noise exposure is cumulative and irreversible. But with proper hearing protection and regular audiometric monitoring, it is entirely preventable.

At Excel Audiology, we provide occupational hearing health services including baseline and annual audiometric testing, hearing conservation counseling, and custom hearing protection designed for the demands of your industry.

OSHA and Hearing Conservation

OSHA requires employers to implement hearing conservation programs when workers are exposed to an 8-hour time-weighted average (TWA) of 85 dB or greater. These programs must include noise exposure monitoring, annual audiometric testing, provision of hearing protection, and employee training.

Even if your employer provides hearing protection, it must fit correctly and be worn consistently. A poorly fitted earplug provides far less protection than its rated NRR (Noise Reduction Rating) suggests — which is exactly why custom-fit protection outperforms generic options.

Industries With High Noise Exposure Risk

Workers in the following industries are at elevated risk for occupational noise-induced hearing loss:

  • Construction and heavy equipment operation
  • Manufacturing and assembly
  • Agriculture (tractors, chainsaws, power equipment)
  • Military service
  • Emergency response (firefighting, law enforcement)
  • Entertainment and event production
  • Airport ground crew and aviation
  • Maritime and shipyard work
  • Woodworking and carpentry

Baseline and Annual Audiometric Testing

Occupational audiometric testing establishes your hearing baseline at the start of employment and monitors for changes year over year. Early detection of noise-induced threshold shifts allows for timely intervention — including improved hearing protection compliance — before permanent damage becomes severe.

At Excel Audiology, we provide both individual and group occupational audiometric evaluations for local employers and workers.

Custom Industrial Hearing Protection

For workers who need maximum comfort and consistent wear throughout a long shift, custom-fit ear protection significantly outperforms disposable foam earplugs in both protection level and daily compliance. We fit workers with:

Custom Solid Earplugs

Maximum passive attenuation for high-noise environments.

Filtered Custom Earplugs

Reduce hazardous noise while still allowing speech and situational awareness.

Banded Protectors

Convenient for workers who need to frequently remove and replace protection.

Protect Your Hearing — and Your Career

Occupational hearing loss doesn’t just affect your health — it affects your livelihood. Many skilled tradespeople, military veterans, and industrial workers suffer preventable hearing loss that impacts their ability to communicate on the job and in everyday life. We encourage all workers in high-noise environments to get a baseline hearing evaluation and explore custom protection options.

Frequently Asked Questions

Yes. Under OSHA’s hearing conservation standard (29 CFR 1910.95), employers must provide hearing protectors at no cost to employees exposed at or above the action level of 85 dB TWA.

If you have to raise your voice to be heard by someone an arm’s length away, the noise level is likely above 85 dB — potentially hazardous with prolonged exposure. A formal noise survey by your employer can confirm specific levels.

No. Noise-induced hearing loss is permanent. This is why prevention and early monitoring are so critical. Once hair cells in the cochlea are damaged, they do not regenerate.

An audiologist — like Dr. Rickman at Excel Audiology — is the most qualified professional to conduct comprehensive audiometric evaluations and counsel you on hearing protection and conservation.
