Hearing Conservation Program Requirements for California Facilities
If you’re a California employer with noisy operations, the question that brings most facilities to this page is some version of: do we need a hearing conservation program, and if we do, what does it actually take to put one in place?
If you’re a California employer with noisy operations, the question that brings most facilities to this page is some version of: do we need a hearing conservation program, and if we do, what does it actually take to put one in place?
The short answer: California requires a documented hearing conservation program once employee noise exposure reaches an 8-hour time-weighted average of 85 dBA. That’s the action level under Title 8, Section 5097 of the California Code of Regulations. (This page covers general-industry workplaces under Cal/OSHA Article 105. Agriculture, construction, and oil and gas well drilling and servicing operations are exempt from §§5097–5100 and may have different noise requirements.) If your facility is at or above that line, the program is mandatory, and ear protection on the floor by itself doesn’t satisfy it. If you’re not sure whether you’re above or below the line, you need a noise survey first to find out. This page covers both situations: what a compliant program contains, how CDMS develops and administers it, and how to tell whether your facility actually needs one.
Do You Need a Hearing Conservation Program?
When we walk a California facility, the question of “do you need this?” usually answers itself within the first hour. These are the patterns we see most often:
- Your noise survey came back at or above 85 dBA TWA for one or more job roles. That triggers the program, even if exposures are intermittent or only some employees are affected.
- Employees already wear hearing protection but you don’t have a written program. PPE on the floor is not the same as a documented program with monitoring, audiometric testing, training, and recordkeeping. This is the single most common gap we find.
- You received a regulatory letter or had a Cal/OSHA inspection. Sometimes the letter asks for a noise survey, sometimes for the program itself. Either way, there is a clock.
- Your existing program is out of date. A program that was written before a major equipment change, a layout change, or a workforce expansion is unlikely to still reflect actual exposure. We routinely find programs that were partially implemented and then quietly stopped tracking equipment additions.
- A gap assessment or Comprehensive Compliance Management onboarding flagged hearing conservation as missing. Most clients learn they need a program this way, not from a regulator.
- You’re under the line but want to confirm it. Facilities that moved, added equipment, or changed shifts often need to remeasure. Previous data doesn’t carry over.
If any of those describe your situation, hearing conservation is on your list. If none of them do and your operations are quiet (offices, light assembly, warehousing without loud forklifts or compressors), you may not need a program at all. The path to certainty is a noise survey, not a guess.
What a Compliant Program Actually Contains
A hearing conservation program is not a single document. Under Title 8, Section 5097, a compliant California program has to include:
A written plan
Tied to the specific facility: areas requiring protection, the equipment that drives the exposure, the job roles enrolled, and program administration responsibilities.
A monitoring and sampling strategy
That identifies which employees must be in the program. This is built on the results of a noise survey.
An audiometric testing program
With a baseline audiogram for each enrolled employee and annual tests after that.
Hearing protection
With a noise reduction rating adequate for measured exposure, plus selection, fit, and replacement processes.
Annual employee training
Covering the effects of noise, the purpose of audiometric testing, and the selection and use of hearing protectors.
Recordkeeping
For noise measurements and audiograms.
Program administration
A designated administrator, supervisor responsibilities, signage at high-noise areas, and a process for updating the program when the facility changes.
Each component has specific requirements. The audiometric baseline has to be preceded by at least 14 hours without exposure to workplace noise (§5097(c)(6)). The baseline itself generally has to be obtained within 6 months of an employee’s first exposure at or above the action level (§5097(c)(8)). If a mobile test van is used, Cal/OSHA allows testing within one year, provided employees have an opportunity for testing. If the baseline is not obtained within 6 months under that approach, hearing protectors must be provided and worn until the baseline is obtained (§5097(c)(9)). When a standard threshold shift is identified on an annual audiogram, the employee has to be informed in writing within 21 days (§5097(d)(4)). These are the details that separate a program that passes a Cal/OSHA review from one that doesn’t.
The 85 dBA Action Level and the 90 dBA PEL
Two numbers do most of the work in this regulation. The 85 dBA TWA is the action level: at or above it, the full hearing conservation program is required. The 90 dBA TWA is the permissible exposure limit (PEL): at or above it, the employer is also required to use engineering or administrative controls to reduce exposure. Cal/OSHA uses a 5 dB doubling rate, which means a 90 dBA exposure for 8 hours is the same dose as 95 dBA for 4 hours or 100 dBA for 2 hours.
Most facilities never reach the PEL but do cross the action level, sometimes by a few decibels in a specific job role. That’s enough to trigger the program. For more detail on the numbers, the dose concept, and how extended shifts (10 or 12 hour days) change the action level, see OSHA noise exposure limits: the 85 dBA action level vs the 90 dBA PEL.
How CDMS Builds and Runs the Program
CDMS develops the written program, coordinates the audiometric testing component, delivers the training, and administers the program on an ongoing basis. We’ve been doing this for California facilities since 1988. Here’s how we approach it:
- Discovery and noise data. We start with what you have. If a recent noise survey exists, we use it. If not, we coordinate the survey through our industrial hygiene team’s sound monitoring service before writing the program. The program has to be built on real data, not assumptions.
- Written program development. We build the written program from a California-specific template, customized to your facility. That includes the policy, the sound level readings, the methods of compliance, the audiometric testing procedure, the recordkeeping structure, the training plan, and the appendices that name your equipment, your job roles, and your protected areas. We make a conservative call on the threshold: rather than navigating Cal/OSHA’s tiered hearing protection system, we recommend requiring hearing protection at the action level (85 dBA) for all exposed employees. It’s simpler to administer, easier to enforce, and more defensible if an inspector walks in.
- Audiometric testing coordination. This is where we want to be precise about the service boundary. CDMS does not perform audiograms. We coordinate audiometric testing with qualified testing providers, schedule the baseline and annual tests, receive and review the results, compare each annual test to the baseline for standard threshold shifts, and update the program based on what the testing shows. That’s the part of the program most consulting firms either skip or hand back to the client. We don’t. More on how this works in audiometric testing for hearing conservation.
- Training. We deliver hearing conservation training in English or Spanish, in person or through a learning management system depending on workforce size and computer access. If you already have training in place and want to keep it, we can review it, certify whether it meets the regulatory requirements, and write up the syllabus rather than replace what’s working. More on what the training has to cover in hearing conservation training requirements.
- Ongoing administration. Programs that get written and shelved fail. We administer the program as part of a Comprehensive Compliance Management relationship: refresh training annually, coordinate the next round of audiograms, update the program when you add equipment or change a process, and review the records during regular site visits.
The Process, Start to Finish
A typical CDMS engagement looks like this:
- 1ScopingWritten quote with scope and fixed price.
- 2Noise survey (if needed)Noise survey report identifying which job roles cross the action level.
- 3Enrollment determinationList of enrolled job roles and a sampling strategy for future monitoring.
- 4Written programWritten hearing conservation program ready for adoption.
- 5TrainingDocumented training records for each enrolled employee.
- 6Audiometric testing coordinationBaseline and annual audiograms on file, STS comparisons performed.
- 7Ongoing administrationA program that stays current and stays compliant.
| Step | What happens | Output |
|---|---|---|
| 1. Scoping | Phone or on-site conversation about your operation, noise sources, headcount, and any existing program documents or noise data. | Written quote with scope and fixed price. |
| 2. Noise survey (if needed) | Our consultant comes to your facility to conduct dosimetry on representative employees and area sound level readings on equipment. | Noise survey report identifying which job roles cross the action level. |
| 3. Enrollment determination | We compare exposure data against the action level and identify the employees who must be in the program. | List of enrolled job roles and a sampling strategy for future monitoring. |
| 4. Written program | We develop the program document customized to your facility, including the policy, methods of compliance, training plan, recordkeeping framework, and site-specific appendices. | Written hearing conservation program ready for adoption. |
| 5. Training | Initial training delivered in English or Spanish, in person or via LMS, depending on workforce. | Documented training records for each enrolled employee. |
| 6. Audiometric testing coordination | We schedule baseline audiograms generally within 6 months of first exposure (up to one year if a mobile test van is used) and annual tests after that, with qualified testing providers. | Baseline and annual audiograms on file, STS comparisons performed. |
| 7. Ongoing administration | Annual training refresh, annual audiometric cycle, program updates when the facility changes, recordkeeping maintained. | A program that stays current and stays compliant. |
The first four steps usually happen in the first months of the engagement. The recurring steps (training, audiograms, monitoring as needed) cycle annually after that.
Title 8, Section 5097: The California Frame
Federal OSHA covers occupational noise exposure under 29 CFR 1910.95. California adopted its own version, with some specific differences, under Title 8, Section 5097. For California employers, §5097 is the controlling regulation, and Cal/OSHA is the enforcing agency. The thresholds are the same (85 dBA action level, 90 dBA PEL), but the recordkeeping framework and a few procedural requirements differ. Noise exposure measurements have to be retained for at least 2 years; audiometric test records have to be kept for the duration of the affected employee’s employment. (Recordkeeping is addressed in Title 8, Section 5100.) For a full breakdown of how §5097 maps to program requirements, see Cal/OSHA hearing conservation program requirements.
Engineering Controls: The Alternative Most Firms Don’t Bring Up
A hearing conservation program is a recurring obligation. Once a facility is enrolled, the testing, training, and recordkeeping cycle runs every year for as long as the noise exists. That cost adds up.
There’s another option that we raise with every client whose noise profile is borderline: engineer out the exposure. If a process change, an equipment enclosure, a barrier, or a relocation can bring exposure below 85 dBA, the program obligation goes away. We’ve watched clients eliminate a single noisy operation and remove an entire enrolled job role from the program. Most competitors selling hearing conservation services have no reason to lead with that option. We do, because it’s often the lower-total-cost answer over five years. The honest comparison between engineering controls, administrative controls, and PPE is in engineering and administrative controls for workplace noise.
How Hearing Conservation Fits a Broader Safety Program
Hearing conservation is rarely the first program a facility builds and rarely the only one it needs. For most California industrial sites, the sequence is Injury and Illness Prevention Program first, then PPE assessment, then hearing conservation, then lockout/tagout and other specialized programs. The reason is practical: hearing conservation requires noise data and a defined population of enrolled employees, and that information surfaces during the gap assessment that establishes the rest of the safety program. Once the program is in place, it lives alongside everything else as part of ongoing compliance management. For how the programs fit together, see hearing conservation in your broader safety program.
Frequently Asked Questions
When is a hearing conservation program required in California?
When employee noise exposure equals or exceeds an 8-hour time-weighted average of 85 dBA. That’s the action level under Title 8, Section 5097. Whether your facility is at that level is determined by a noise survey, not by how loud the floor feels.
Does ear protection on the floor satisfy the requirement?
No. Hearing protection is one component of a compliant program, not a substitute for it. A program has to include monitoring, audiometric testing, training, recordkeeping, hearing protection selection, and a written plan. Facilities that distribute earplugs without the rest are out of compliance even if every employee wears them.
Does CDMS perform the audiometric testing?
No. CDMS coordinates audiometric testing with qualified testing providers and builds the program around the results. Testing providers typically don’t write or administer programs, and program consultants don’t perform audiograms. We handle the coordination so the testing happens on schedule and the results feed back into the program.
Can we keep doing hearing conservation training in-house?
Yes, if the in-house training meets the requirements. The trainer should understand the subject well enough to deliver the required topics and answer questions, and the employer should keep a syllabus and attendance records to demonstrate that the training occurred. We can review your existing training, certify whether it meets §5097 requirements, write up the syllabus, and document the training records. We can also deliver the training ourselves in English or Spanish if that’s the better fit.
How long do we have to keep noise records and audiograms?
Under California recordkeeping rules, noise exposure measurements must be retained for at least 2 years, and audiometric test records must be kept for the duration of the affected employee’s employment. That’s longer than most facilities expect.
What if our noise levels are borderline?
Two options. One: a noise survey to confirm whether you’re above or below the 85 dBA action level. Two: an engineering controls assessment to see whether reducing the noise at the source is more cost-effective than a recurring program. We’ll tell you honestly which one your facility should do first.
