How to Write a Hearing Conservation Program Policy: A Complete Guide for Employers

Updated March 2026  ·  29 CFR 1910.95  ·  11 min read

A hearing conservation program policy is more than a compliance document — it's the architecture that holds every other program element together. When OSHA shows up, the written policy is the first thing they ask for. When a workers' compensation claim is filed, it's the first thing plaintiff's counsel requests.

Soundtrace helps employers build and document every element of a compliant hearing conservation program — from noise monitoring through professional supervisor review — with the records infrastructure needed to back up whatever the written policy commits to.

Why a Written Policy Matters Even When OSHA Doesn't Explicitly Require One

OSHA 1910.95 does not include a line that says “employers must maintain a written hearing conservation program.” That said, when an OSHA compliance officer arrives, the first step is usually requesting the written program. An employer who cannot produce one faces an immediate credibility gap.

Write the policy. The absence of an explicit OSHA mandate for a written program is not a reason to skip it — the operational and legal case for documentation is overwhelming.

Section 1: Scope and Purpose

The policy should state its scope clearly: which facilities, departments, and job classifications are covered, and which regulatory standard(s) it satisfies (29 CFR 1910.95 for general industry). Include the effective date and version number.

Section 2: Coverage Criteria and Enrollment

Specify the 85 dBA TWA action level threshold that triggers enrollment and how that determination is made. Employees are enrolled when their measured or anticipated noise exposure equals or exceeds the action level. Address how new hires in potentially noisy jobs are handled during the period between hire and formal noise exposure assessment.

Section 3: Noise Monitoring

Specify instrumentation type (personal dosimetry preferred for variable exposures), OSHA compliance settings (A-weighting, 5 dB exchange rate, 80 dBA criterion level), calibration verification procedure, and re-monitoring triggers: new equipment installation, production rate changes, process modifications, engineering control implementation, and STS findings in previously unidentified workers.

Section 4: Audiometric Testing

Address baseline audiogram requirements (6-month window from first qualifying exposure, 14-hour quiet period), annual audiogram scheduling (12 months from each individual's previous test), test environment compliance with OSHA Appendix D ambient noise criteria, equipment calibration schedule, and professional supervisor responsibilities.

Section 5: Hearing Protection

Specify which device types are available, the adequacy evaluation method (derated NRR or PAR from fit testing), required minimum attenuation per noise area, mandatory vs. voluntary use thresholds (voluntary at action level; mandatory at PEL), and STS response protocol for HPD reassessment. See: HPD Fit Testing: Quantitative Methods and OSHA Requirements.

Section 6: Training

Specify: initial training before first qualifying exposure; annual retraining within 12 months of previous; four required content areas from 1910.95(k); delivery format; language accommodation; and how completion is documented per employee. See: OSHA Hearing Conservation Training Requirements.

Section 7: Standard Threshold Shift Response Protocol

1. Detection: Annual audiogram comparison triggers apparent STS flag for professional supervisor review
2. Professional supervisor review: Confirms STS, evaluates work-relatedness, considers age correction
3. Optional retest: Within 30 days of the annual audiogram showing apparent STS
4. Employee notification: Written notification within 21 days of supervisor determination
5. HPD reassessment: Review and refit if current devices are inadequate
6. OSHA 300 recordability determination: Apply 1904.10 criteria; record within 7 days if criteria are met

The 21-day notification clock starts on the supervisor's determination date — not on the audiogram date. Specify the timeline clearly so no step gets missed under time pressure.

Section 8: Recordkeeping

Specify record categories and retention: monitoring records (2 years minimum), audiometric records (employment + 30 years), training records, STS notification records. Specify storage system, access procedures, and employee transfer protocols. The 30-year audiometric retention is the element most likely violated by employers who don't plan for it. See: OSHA Recordkeeping Compliance.
