The OSHA Hearing Conservation Program is a federally mandated set of procedures designed to prevent permanent noise-induced hearing loss in workers exposed to high noise levels on the job. If your facility hits 85 dBA as an 8-hour time-weighted average, you are legally required to have one -- and it must cover six specific elements. This guide explains every requirement, who it applies to, and exactly what "having a program" actually means under OSHA law.
An OSHA Hearing Conservation Program is not a binder on a shelf -- it is an active, continuing program with six mandatory components: noise monitoring, audiometric testing, hearing protection, training, recordkeeping, and access to information. Missing any one element is a citable violation.
An OSHA Hearing Conservation Program (HCP) is a structured, ongoing workplace program required under 29 CFR 1910.95 to protect employees from noise-induced hearing loss. The CDC estimates approximately 22 million workers are exposed to hazardous noise levels each year in the United States.
The term appears in Section 1910.95(c): the employer shall administer a continuing, effective hearing conservation program whenever employee noise exposures equal or exceed an 8-hour TWA of 85 decibels. The key word is continuing -- a one-time audiogram or a box of earplugs does not constitute an HCP.
Any general industry employer must implement an HCP when any employee's noise exposure equals or exceeds 85 dBA TWA -- the action level.
| Industry Sector | Common Noise Sources | Typical dBA Range |
|---|---|---|
| Metal Manufacturing | Stamping presses, grinders, metal impact | 90-105 dBA |
| Food Processing | Packaging lines, conveyors, blowers | 85-98 dBA |
| Automotive Assembly | Power tools, riveting, press lines | 88-102 dBA |
| Warehousing and Distribution | Forklifts, dock equipment, conveyors | 80-92 dBA |
| Printing and Publishing | Web presses, folding machines | 85-95 dBA |
| Paper and Pulp | Chippers, digesters, paper machines | 90-110 dBA |
| Utilities and Power Generation | Turbines, generators, boiler rooms | 88-105 dBA |
| No. | Component | OSHA Paragraph | Key Trigger |
|---|---|---|---|
| 1 | Noise Monitoring | Section 1910.95(d) | When exposures may reach or exceed 85 dBA TWA |
| 2 | Audiometric Testing | Section 1910.95(g) | All employees at or above action level |
| 3 | Hearing Protection Devices | Section 1910.95(i) | Available at action level; mandatory at PEL |
| 4 | Training Program | Section 1910.95(k) | Annual, for all employees at or above action level |
| 5 | Recordkeeping | Section 1910.95(m) | Ongoing; audiometric records for duration of employment |
| 6 | Access to Information | Section 1910.95(l) | Employees must receive program info and standard |
Noise monitoring is the first step. You cannot know whether employees are exposed above the action level without measuring the noise they experience throughout a representative shift. The two primary methods are sound level meters (SLMs) for area mapping and personal noise dosimeters worn by individual workers for cumulative exposure assessment.
Monitoring results must be made available to affected employees and must be repeated whenever process, equipment, or production changes could affect noise exposure.
Audiometric testing is the diagnostic core of every hearing conservation program. It tells you whether workers' hearing is deteriorating and whether your controls are actually working.
Must be completed within 6 months of an employee's first exposure at or above the action level (or within 1 year if a mobile testing van is used, with mandatory HPD use in the interim).
Must be conducted at least once every 12 months. If a Standard Threshold Shift (STS) of 10 dB or more is detected at 2000, 3000, or 4000 Hz, the employer must take follow-up action within 21 days.
Many employers are moving away from expensive, disruptive mobile van audiometry toward in-house testing with software platforms like Soundtrace -- gaining real-time results, instant STS flagging, and built-in recordkeeping. Compare the two approaches here.
HPDs must be made available to all employees exposed at or above the action level, at no cost, with a variety of suitable options to choose from. Use of HPDs becomes mandatory for any employee whose noise exposure equals or exceeds the 90 dBA PEL. The selected HPD must provide sufficient attenuation to reduce effective exposure to at least 90 dBA -- or 85 dBA for employees who have experienced an STS.
Annual training is required for every employee in the hearing conservation program. It must cover:
Under Section 1910.95(l), employers must provide affected employees with access to the OSHA noise standard, the employer's hearing conservation program, and any noise monitoring results that affect them.
OSHA 1910.95 does not explicitly require a written HCP, but you should absolutely have one in writing. During an OSHA inspection, a compliance officer will ask to see your program. Without a written document demonstrating that each of the six components exists and is being carried out, you will likely face citations.

| Program Element | Outsourced (per employee/yr) | In-House (per employee/yr) |
|---|---|---|
| Audiometric testing | $40-$80 | $8-$20 |
| Noise monitoring | $500-$2,000 per survey | Equipment cost amortized |
| Training | $15-$40 per employee | $5-$15 per employee |
| Hearing protection | $3-$25 per employee | $3-$25 per employee |
Companies that bring audiometric testing in-house with Soundtrace typically see 50-70% cost reductions compared to mobile van vendors, while gaining real-time STS flagging and compliance audit trails.
A hearing protection program refers only to the provision and use of HPDs. A hearing conservation program is the full OSHA-mandated program -- which includes noise monitoring, audiometric testing, hearing protection, training, and recordkeeping. The two terms are not interchangeable.
At a minimum, programs should be reviewed annually and whenever significant changes in equipment, production processes, or workforce occur that could affect noise exposures.
The employer is ultimately responsible. In practice, administration is typically assigned to a safety manager, EHS director, or occupational health conservationist (OHC). For audiometric testing oversight, a licensed audiologist or physician must review problem audiograms.
They must be enrolled in the hearing conservation program immediately. A baseline audiogram must be completed within 6 months, hearing protection must be provided from day one, and they must complete training within the first annual cycle after hire.
Soundtrace replaces fragmented, paper-based HCP management with a single digital platform -- audiograms, noise monitoring, fit testing, training, and records all in one place.
