How Compliance Tracking Improves Hearing Test Completion and OSHA Compliance

Hearing test due dates are hard to track. Each one runs from a different employee's first exposure, and every required test that passes its due date leaves that employee out of compliance with OSHA 1910.95. These five numbers show which crews are falling behind, and turn a compliance rate into a list of employees to schedule.

Tracking audiometric testing compliance means knowing, on any given day, which employees are past due for a baseline or annual audiogram, which are waiting on a retest or a follow-up action, and which completed tests haven’t been reviewed yet.

Those lists can change daily, because OSHA’s audiometric testing requirements are written per employee; each person’s due dates come from their own first exposure date. Knowing what share of your active employees are current, broken out by site and team, turns those dates into a number you can act on.

Why do hearing tests get missed?

Because due dates correspond to each employee’s own first exposure date, not a company-wide calendar, so they never collect into a single testing season.

Under OSHA regulation 29 CFR 1910.95, you have to establish a valid baseline audiogram within six months of an employee’s first exposure at or above the hearing conservation program action level of 85 dBA over an 8-hour time-weighted average (TWA). If you use mobile test vans, that window is one year, but if the baseline falls more than six months after first exposure, the employee must wear hearing protectors beyond those six months until you obtain it. After the baseline, you owe each employee a new audiogram at least annually.

Each of the following either puts an employee out of compliance or leaves an obligation open:

  • New hires start their own clock. Each one needs a valid baseline within six months of their own first exposure (one year with mobile test vans). Miss that deadline and the employee is out of compliance until a baseline is on file.
  • Retests run on a shorter clock. When an annual audiogram shows a standard threshold shift (STS), you may obtain a retest within 30 days and treat it as the annual audiogram. Miss the 30-day window and the original shift stands, along with every notification and follow-up obligation that comes with it.
  • A shift starts more clocks. Once a shift is determined, you have 21 days to notify the employee in writing, and unless a physician determines the shift isn’t work-related or aggravated by occupational noise, follow-up obligations attach: fitting or refitting hearing protectors, training or retraining, and referral for evaluation where appropriate (29 CFR 1910.95(g)(8)). An employee can be tested on time and still have an open obligation.
  • Fixed testing dates don’t match rolling due dates. Whatever your program uses (an on-site booth day, a clinic appointment block, a scheduled provider visit), employees keep coming due in between.

Missed deadlines show up in OSHA enforcement data. In fiscal 2025, the most commonly cited failure under 1910.95(g) was having no audiometric testing program at all, followed by missing annual audiograms and then missing baseline audiograms.

What does compliance mean for a hearing testing program?

For a hearing testing program, compliance means every employee who is owed a test has had it on time, and every shift that turns up has been handled on time. Under 29 CFR 1910.95(g), that covers baselines and annual audiograms completed by their due dates, standard threshold shifts retested within 30 days when you choose to retest, employees notified in writing within 21 days of a determination, and the follow-up actions that attach to a shift.

Your compliance percentage measures test currency: the share of active employees whose required audiogram is on file and whose next test isn’t due yet. An employee is current from the day that audiogram lands, and overdue the day a required test date passes without one.

Current isn’t the same as finished. The audiogram still has to be compared against that employee’s baseline, and if that comparison shows a shift, the notification and follow-up actions have to happen too (29 CFR 1910.95(g)(7) and (g)(8)). None of that moves the compliance percentage, which is why pending reviews, employees waiting for retests and outstanding follow-ups are counted separately. The percentage tells you about testing currency. The counts underneath it tell you about the program.

Which hearing testing compliance numbers should you track?

Five numbers cover it: four counts, and the percentage they produce.

Number Why it matters
Active employees Your denominator. It moves with hiring, transfers, and role changes, so it has to come from live data.
Employees tested Tests actually completed, meaning the audiogram is in hand. A booked appointment doesn’t count, and neither does a test whose audiogram you don’t have yet. Whether that test has been reviewed, and whether a shift triggered follow-up actions, are tracked in the row below.
Overdue, split by annual, initial, and retest Splitting the total tells you which process to go fix. A pile of overdue initials points to onboarding, overdue annuals to scheduling, overdue retests to follow-up.
Outstanding follow-ups, retests, and pending reviews Employees who’ve been tested but aren’t finished. A shift awaiting a retest, an open follow-up action, or a completed test that hasn’t been reviewed is still an open obligation.
Compliance percentage The headline. It’s the number leadership asks for, and the one that decides whether anyone looks closer. It’s only as accurate as the counts above it.

Track all five, and the data answers two questions: how the program is doing and what to do next.

Why isn’t one organization-wide compliance number enough?

An overall score tells you whether to worry. It doesn’t tell you how to fix it.

Hearing Testing, Evolved

FDA-listed tablet audiometry. OSHA compliant. Test anywhere — no sound booth required.

Say your dashboard shows 95% overall compliance across roughly 1,900 active employees. In the same view, one crew sits at 54%. The 95% tells you the program looks healthy. The 54% tells you which crew to investigate.

A corporate average won’t tell you why you’re not at 100%, and it won’t separate a crew out on its own line. The questions that would explain a gap are local ones: how that crew is scheduled around shift changes, who owns the follow-up list there, whether new hires get tested at onboarding. You can’t ask those questions until you know which crew to ask. For the operational side, see managing a hearing conservation program across multiple locations.

Where should you set your hearing testing compliance thresholds?

Sort sites into compliant, at risk, critical, and non-compliant, and you will know which sites need attention first.

Where you draw those lines is a management choice. OSHA doesn’t grade programs on a percentage at all. Its requirements apply per employee, so an employee tested late is a gap, regardless of your overall number, which means the only score that represents full compliance is 100%. Thresholds help you triage the distance between your number and 100%. Pick cut points that match how your organization already reports safety metrics, so a hearing testing number sits alongside your other measures without needing a translation. If leadership treats anything under 95% as a problem, don’t set your compliant threshold at 80%.

How do you turn a compliance percentage into scheduled tests?

Knowing a crew is at 54% doesn’t automatically increase your test completion rates. Someone has to get from the number to a list of names, each with a last test date and a next due date, and hand that list to whoever schedules testing. If that means exporting records and reconciling them by hand, the list is only as current as the last time someone rebuilt it.

Tracking only helps increase OSHA compliance when the numbers link to the names associated with them.

How does the SHOEBOX PureTest Data Management Portal help you close compliance gaps?

The Compliance Dashboard is the first screen in the SHOEBOX PureTest Data Management Portal after you log in. Across the top, you will see your number of active employees, completed tests, employees overdue for testing, and an overall compliance score, color-coded to the compliance thresholds you set. You don’t need to request a report; you see your program’s status without clicking anything.

The Compliance Dashboard summary shows active employees, completed tests, employees overdue for testing, and an overall compliance score. Sample data shown.

See what’s outstanding, not just what’s overdue. The General Overview tab breaks your program into groups: employees overdue for testing, those with outstanding follow-up actions, those waiting for a retest, and, for reviewing audiologists, tests still pending review. Each group links straight to the employees behind it.

See every group at once. A project is whatever grouping of employees you want it to be: a site, a shift, a crew, a department. You set them up yourself, so they match how your program is organized. The Project Overview tab then gives you one row per project, with total numbers of active and inactive employees, employees tested, STS, Recordable STS, overdue counts, and a compliance percentage per project. Filter by compliance status, search by project name, or sort by any column, and your weakest projects come to the top. If you only manage some of them, the project selector can narrow the whole view to yours.

See which kind of overdue you’re looking at. Overdue counts break out by annual, initial, and retest, so you can tell a new-hire backlog from a follow-up backlog without opening anything.

Scrolling the project table to the right reveals overdue counts split by annual, initial, and retest testing. Sample data shown.

Get to names in one click. Every count, on the dashboard and in the tables, is a link to a list of the employees behind it. For example, if you select an overdue count, you get the list of employees overdue for testing, with last tested and next test due dates. Tables are also searchable by employee name. Who sees which level of detail is set by your program administrators, so the people with access work from their lists.

Selecting an overdue count opens the list of employees behind it, with last tested and next test due dates. Sample data shown.

Find what already works. Once your sites sit in one sortable table, your strongest performer is as visible as your weakest. Now you can replicate whatever the site at 96% is doing differently, because you know where to look and who to ask.

Report on the same numbers you act on. Recordable STS sits in its own column, so the shifts you need to review for your OSHA 300 log come from the same view you use to chase overdue tests.

Access is built around who should see what. Administrators with access to protected health information (PHI) see compliance data for the whole organization. Users with PHI access but no administrator rights see the same views, limited to the projects assigned or shared with them. Administrators without PHI access can set the compliance thresholds but never see employee data. That separation is deliberate: hearing test results are health information, and the dashboard only ever shows a user the employees they’re responsible for.

The project table and the employee lists behind it are refreshed overnight, and a banner shows when they were last updated, so a test completed this morning appears there tomorrow. The summary figures across the top and the General Overview tab are live.

How do you test employees as they come due?

A list of names with due dates is only useful if you can test the people on it.

Employees come due all year, so staying current means being able to test year-round. The SHOEBOX PureTest solution includes a boothless, tablet-based audiometer, clinically validated for use outside a sound booth, that stays at your facility. A qualified technician on your team can test new hires in their first week, catch a retest inside the 30-day window, and pick up whoever missed a testing day, without waiting for the next scheduled event.

Frequently Asked Questions

What counts as an overdue audiometric test?

An audiometric test is overdue once an employee’s required test date passes without a completed audiogram on file. Under 29 CFR 1910.95, a baseline is due within six months of an employee’s first exposure at or above the action level, an 8-hour time-weighted average of 85 dBA, or within one year where mobile test vans are used. An annual audiogram is due at least every year after that.

When does an audiometric test count as complete?

A completed audiogram on file clears that employee from the overdue count, but it doesn’t finish the obligation. Under 29 CFR 1910.95(g)(7)(i), each annual audiogram has to be compared against that employee’s baseline to confirm the test is valid and to determine whether a standard threshold shift has occurred. Until that comparison is done, the test sits as a pending review rather than an overdue test, which is why the two are counted separately. If the comparison shows a shift, the obligation stays open until the follow-up actions are done as well: written notification within 21 days, hearing protector fitting or refitting, training, and referral for evaluation where appropriate (29 CFR 1910.95(g)(8)).

How do you calculate a hearing testing compliance rate?

Divide the number of active employees with a current audiogram by the total number of active employees, then multiply by 100. An employee is current when their required baseline or annual audiogram is complete, and the next one isn’t due yet. You can state the same figure in reverse, as the percentage of active employees with overdue tests (your non-compliance rate). When calculating compliance rates, always use active employees as the denominator: inactive and former employees aren’t owed a test, so including them gives you a rate that doesn’t accurately represent your program.

What’s the difference between an STS and a Recordable STS?

A standard threshold shift (STS) is a change in hearing threshold relative to an employee’s baseline audiogram averaging 10 dB or more at 2000, 3000, and 4000 Hz in either ear (29 CFR 1910.95(g)(10)). It requires you to notify the employee in writing within 21 days of the determination, and to take the follow-up actions in 1910.95(g)(8): fitting or refitting hearing protectors, training or retraining, and referral for evaluation where appropriate. A Recordable STS is narrower. It’s an STS where the employee’s hearing level in that same ear also averages 25 dB or more above audiometric zero at those same frequencies. Audiometric zero is the 0 dB reference point on an audiogram, so that works out to an average hearing level of 25 dB or worse. Meeting both conditions makes a case a candidate for the OSHA 300 log, the Log of Work-Related Injuries and Illnesses. You may retest within 30 days, and if the retest doesn’t confirm the shift, you don’t record it. The case also has to be work-related: if a physician or other licensed healthcare professional determines it isn’t, or that occupational noise didn’t significantly aggravate it, it isn’t recorded (29 CFR 1904.10(b)(4) to (b)(6)). Every Recordable STS is an STS. Not every STS is recordable.

Does OSHA require a minimum compliance percentage?

No. 29 CFR 1910.95 sets testing obligations for each exposed employee and doesn’t establish a program-level score or completion-rate target. A compliance percentage is an internal management measure that helps you find the gaps. It carries no regulatory standing, and a good score doesn’t substitute for testing every individual employee on time.

How often should you review hearing testing compliance data?

The OSHA regulation doesn’t set a review cadence, and a fixed interval can lag. Employees come due on their own schedules throughout the year, so a monthly or quarterly review leaves some of them overdue for weeks before anyone looks. The shortest clocks make that concrete. You have 30 days to retest an employee after an annual audiogram shows a standard threshold shift of 10 dB or more from their baseline, averaged at 2000, 3000, and 4000 Hz. You have 21 days to notify that employee in writing after the determination (29 CFR 1910.95(g)(7)(ii) and (g)(8)(i)). Being able to check any day, rather than waiting for a scheduled report, gives you time to act before those windows close.
