Construction Noise: Does OSHA's 1926.52 Require the Same Hearing Conservation Program as 1910.95?

What does OSHA's construction noise standard actually require?

29 CFR 1926.52 sets a permissible exposure level (PEL) table for construction, Table D-2, that caps exposure at 90 dBA for an 8-hour day, sliding down to 115 dBA for 15 minutes or less. Where measured noise exceeds the table, 1926.52(b) requires feasible administrative or engineering controls first, and only when those controls can't bring levels within the table does personal protective equipment become the fallback. Paragraph (d)(1) adds one more line: "a continuing, effective hearing conservation program shall be administered" wherever levels exceed the table values. That sentence is the entire hearing conservation requirement in the construction standard. It names no baseline audiogram deadline, no annual testing cycle, no standard threshold shift calculation, and no audiometric test room noise limit, the way 1910.95 spells out for general industry.

How is 1926.52 different from 1910.95's hearing conservation program?

General industry's 1910.95 triggers a full program, baseline audiogram, annual audiogram, STS tracking, training, and recordkeeping, at an 85 dBA 8-hour time-weighted average action level. Construction's 1926.52 uses a 90 dBA PEL table instead of an 85 dBA action level, and it doesn't define what "a continuing, effective hearing conservation program" has to contain beyond that phrase. OSHA's own enforcement practice fills the gap: compliance officers on construction sites generally look to 1910.95's program elements, audiometric testing, training, recordkeeping, as the benchmark for what "effective" means, even though 1926.52 never cross-references 1910.95 by number. An employer running a construction crew at 88 dBA 8-hour TWA is under the construction PEL table and not yet required to act, while the same 88 dBA reading on a general industry floor would already be at the 85 dBA action level triggering enrollment.

Element	1910.95 (general industry)	1926.52 / 1926.101 (construction)
Trigger level	85 dBA action level (8-hr TWA)	90 dBA PEL (8-hr TWA, Table D-2)
Hearing conservation program detail	Baseline, annual audiogram, STS, training, recordkeeping spelled out	"Continuing, effective" program required, no elements specified
Audiometric testing required by rule text	Yes, explicit schedule	Not specified in 1926.52 or 1926.101
Hearing protector fitting	1910.95(i), attenuation adequacy standard	1926.101(b), fitted/selected by competent person
Cotton as hearing protection	Not addressed	Explicitly barred, 1926.101(c)

What does 1926.101 require for hearing protection?

1926.101 covers the protective-equipment side in three short paragraphs. Paragraph (a) requires ear protective devices wherever it isn't feasible to bring noise down to the Table D-2 levels through engineering or administrative controls. Paragraph (b) requires that devices inserted in the ear be fitted or selected individually by a competent person, not handed out off a shelf without checking fit. Paragraph (c) rules out plain cotton as an acceptable protector, a leftover from job-site habits that predate modern hearing protection standards. None of the three paragraphs mention audiometric testing; 1926.101 is strictly about the device, not the monitoring program.

Does a multi-employer construction site change who's responsible?

Construction sites routinely run several employers under one general contractor, and 1926.52 applies to each employer for its own employees' exposure, not to the site as a whole. A subcontractor whose crew works inside a steadily noisy demolition zone created by another trade still has to measure its own employees' exposure and respond if their 8-hour TWA crosses the Table D-2 limits, even if the noise source belongs to someone else. Coordinating hearing protection requirements across trades on a shared site, so that one subcontractor's saw cuts don't push a neighboring crew over the PEL without anyone measuring it, is a common gap safety managers miss when they assume noise exposure is handled site-wide by the general contractor.

How Foster handles construction and general industry noise programs differently

When we run on-site occupational health testing for a contractor, we ask up front whether the crew falls under 1926 construction rules or 1910 general industry rules, since that changes both the trigger level we measure against and what we document for the file. For a construction client sitting near the 90 dBA Table D-2 line without a formal audiometric program yet, we build one that mirrors 1910.95's elements, baseline audiogram, annual retest, STS tracking, because that's the benchmark OSHA compliance officers use even though 1926.52 doesn't spell it out. Our hearing testing service logs the measured dBA at each station so a contractor can show, document in hand, which PEL table applied and why. For employers tracking which standard, 1910.95 or 1926.52, governs a given site across a multi-trade job, Foster's Compliance Workspace ties each location's requirement to its CFR citation so the right program follows the right crew.

Frequently asked questions

Is 90 dBA the same as OSHA's action level?

No. The 90 dBA figure in 1926.52's Table D-2 is the construction permissible exposure level, the point where controls and hearing protection become mandatory. General industry's 1910.95 uses a separate, lower 85 dBA action level that triggers enrollment in a hearing conservation program well before the PEL is reached. The two numbers come from different standards and aren't interchangeable.

Does 1926.52 require baseline and annual audiograms by name?

No. The text only requires "a continuing, effective hearing conservation program" without listing baseline or annual testing. In practice, OSHA compliance officers evaluate construction programs against the same elements 1910.95 requires for general industry, so most defensible construction programs include audiometric testing even though the construction rule doesn't name it directly.

Can a construction crew use cotton as hearing protection in a pinch?

No. 1926.101(c) states plain cotton is not an acceptable protective device. It provides negligible attenuation and doesn't meet the standard's requirement for devices that are fitted or selected by a competent person under 1926.101(b).

Who measures exposure when multiple subcontractors work the same noisy site?

Each employer is responsible for measuring and responding to its own employees' noise exposure under 1926.52, regardless of which trade is generating the noise. A subcontractor can't assume the general contractor or another trade has already covered its crew's exposure monitoring.
