Construction employers face a question that general industry employers don’t: which OSHA noise standard governs their workers — 1926.52 (construction) or 1910.95 (general industry)? The answer turns on where the work is being performed and by whom, and the two standards differ in meaningful ways. Understanding the differences isn’t academic — it determines what audiometric testing is required, when workers must wear hearing protection, and what records you need to keep.
Soundtrace provides construction employers with automated audiometric testing and noise monitoring that satisfies both 1926.52 and 1910.95 requirements, building per-worker records across job sites.
1926.52 requires hearing protection when exposure exceeds 90 dBA but does not require audiometric testing or a full hearing conservation program. 1910.95 requires audiometric testing, a full HCP, and recordkeeping beginning at 85 dBA. Construction employers who also operate facilities, shops, or maintenance operations may have workers covered by 1910.95 for those activities — even if the same workers do field construction under 1926.52.
Which OSHA Noise Standard Applies to Your Workers?
The governing standard follows the type of work, not the employer’s industry classification. Workers performing construction, demolition, or renovation activities are covered by 29 CFR 1926.52. Workers performing general industry activities — manufacturing, facility maintenance, production operations — are covered by 29 CFR 1910.95 even if the same employer also does construction work.
The practical consequence: a contractor who builds and also maintains a facility, operates a fab shop, or employs permanent maintenance staff may have workers under both standards depending on their daily tasks.
OSHA 1926.52: Construction Noise Standard in Detail
Under 1926.52, feasible engineering or administrative controls are required when workers are exposed above 90 dBA TWA. When controls are not feasible or are insufficient to reduce exposure below 90 dBA, hearing protective devices must be provided and worn. The standard does not require audiometric testing, does not define an action level that triggers a hearing conservation program, and does not explicitly require annual training.
Because 1926.52 does not require audiometric testing, construction employers have no audiometric baseline or annual record for most workers. When those workers later file workers’ compensation hearing loss claims, the employer has no audiometric documentation to limit their liability or demonstrate what hearing loss predated employment. This is why many construction employers voluntarily adopt 1910.95-style HCPs for their workforce.
OSHA 1910.95: General Industry Standard in Detail
Under 1910.95, the 85 dBA action level triggers the full hearing conservation program: noise monitoring, baseline audiogram within 6 months (or 1 year if mobile van), annual audiometric testing, annual training, hearing protection availability, and audiogram recordkeeping. The STS (standard threshold shift) evaluation requires follow-up audiometry and, where indicated, referral. The full HCP documentation framework creates the per-worker record that protects both the employer and the worker.
When Both Standards Apply to the Same Workforce
Construction employers with shops, yards, permanent facilities, or maintenance operations may need to apply 1910.95 to some workers while 1926.52 covers field crews. The practical approach is to extend 1910.95’s audiometric testing program to the entire workforce — field and facility alike — creating a consistent per-worker record that protects against WC claims regardless of which standard technically applies to a given day’s work.
