Construction workers face some of the highest occupational noise exposures of any industry—yet construction is governed by a separate and older OSHA noise standard. While general industry employers follow 29 CFR 1910.95, construction employers are covered by 29 CFR 1926.52 and 1926.101. These regulations have fewer explicit audiometric testing and training requirements. This guide explains what construction employers must do, where the gaps are, and how to build a practical program that protects workers.
Soundtrace provides noise monitoring, HPD fit testing, and audiometric testing for construction employers through on-site managed service visits, requiring no in-house audiometric infrastructure.
| Requirement | General Industry (1910.95) | Construction (1926.52 / 1926.101) |
|---|---|---|
| Action level | 85 dBA TWA triggers HCP enrollment | Not specified; HPD required at or above 90 dBA TWA |
| PEL | 90 dBA TWA (8-hr) | 90 dBA TWA (8-hr); same table |
| Hearing conservation program | Full HCP required above action level | No equivalent HCP requirement; HPD provision only |
| Audiometric testing | Baseline + annual required above action level | Not explicitly required by 1926.52 |
| HPD provision | Required above action level; mandatory use above PEL | 1926.101: must be provided and fitted at 90+ dBA TWA |
| Training | Required under 1910.95(i)(4) | No explicit training requirement in 1926.52 |
The absence of explicit audiometric and training requirements in 1926.52 does not mean construction employers can skip them. OSHA’s General Duty Clause requires employers to protect workers from recognized hazards even where specific standards are silent. OSHA has cited construction employers for failing to implement audiometric testing programs where noise exposures are consistently high.
Under 1926.101, hearing protection must be provided to workers exposed at or above 90 dBA TWA. Devices must be fitted and plain language instructions provided. OSHA’s interpretation is that “fitted” means the device provides adequate attenuation for the worker’s actual exposure.
Typically 98–110 dBA; dual protection often required
95–105 dBA; earmuffs or foam earplugs with fit testing
85–95 dBA in cab; task-specific assessment needed
Peak exposures above 140 dB; impulsive noise requires separate evaluation
Measure TWA by job classification and task; exposures vary widely on a construction site
Match HPD type and NRR to task-specific exposure; high-noise tasks may require dual protection
Demonstrate insertion technique; issue appropriate HPD for the worker’s primary tasks
Even without an explicit 1926.52 requirement, annual audiometric testing provides early STS detection and litigation protection
Workers at 100+ dBA TWA should have PAR documented to confirm HPD adequacy
Construction employers who treat 1926.52 as a lower bar than 1910.95 are taking on General Duty Clause exposure. The practical standard of care for high-noise construction is converging with general industry requirements.

Unlike 1910.95, the construction standard does not explicitly require audiometric testing or training, though the General Duty Clause has been used to cite employers who fail to address recognized noise hazards.
OSHA 1926.52 does not explicitly require audiometric testing, unlike the general industry standard. However, OSHA has cited construction employers under the General Duty Clause for failing to implement audiometric programs where noise exposures are consistently high. Annual audiometric testing is best practice and provides significant litigation protection.
Workers at or above the 90 dBA TWA PEL must be provided with hearing protection under 1926.101. For tasks producing exposures above 100 dBA TWA such as jackhammer operation or concrete cutting, dual protection is often necessary. HPD type should be selected based on noise level and frequency, and fit testing is recommended for all workers in consistently high-noise roles.
