Hearing conservation program software that shows its work.

HCP Expert keeps the whole OSHA hearing conservation program in one record: audiometric testing, baselines, standard threshold shift, employee notification and the OSHA 300 decision. Every result sits next to the sentence of 29 CFR 1910.95 that it answers.

Seven days, free, with a complete sample program. No card and no contract: the trial runs on fictional data only. Built for the United States; the rules are read from the official eCFR text of 29 CFR 1910.95 and 29 CFR 1904.10.

Right ear of a fictitious worker in HCP Expert: the annual test of October 2, 2026 compared with the reference of October 1, 2024, from 125 to 8000 hertz. The shift at 2000, 3000 and 4000 hertz is +10, +15 and +15 decibels, an average of +13.3 decibels. Below the chart, the method: OSHA standard threshold shift, 1910.95(g)(10)(i), version 1.0.0, and the baseline used.

What it does

The audiometric testing program from the test room to the OSHA 300 log, recorded once and evaluated against the standard.

From the audiogram to the OSHA 300 decision

Each test is recorded with the audiometer, its calibration and the test room. The result compares it with the baseline of each ear, and what the standard requires next becomes an item with a date.

  • Standard threshold shift per ear, with the optional age correction generated from the Appendix F tables. 1910.95(g)(10); Appendix F
  • Baseline and revised baseline kept per ear; the professional decides each revision. 1910.95(g)(9)
  • Written notification to the employee and the recordability decision, each with the rule quoted. 1910.95(g)(8); 1904.10
What follows a test with a standard threshold shift Four steps in order for a fictitious test: test recorded on September 3; standard threshold shift evaluated per ear; employee notified in writing, due within 21 days; OSHA 300 recordability decided under 1904.10. Test recorded Sep 3, with audiometer, calibration and room STS evaluated, per ear Left ear: shift of 13.3 dB against baseline Notify the employee in writing Due within 21 days Decide the OSHA 300 entry Recordability under 29 CFR 1904.10

Who is due, and what is overdue

A due list for the program and a queue for the day. An overdue item raises an alert that stays until someone resolves it, not until someone sees it.

  • Baseline, annual and retest audiograms, with the date each one is due. 1910.95(g)(5), (g)(6), (g)(7)
  • Hearing protector replacement, training and exams required by the exposure group, with the due date derived from the interval your program declares.
  • Add workers to the queue of a day one by one or in a batch.
The Worklist of HCP Expert for a fictitious program: two overdue items, an OSHA 300 Log entry nine days overdue and a training renewal, then two due soon, among them the written STS notice to the worker within 21 days. Each item names the worker, the employer, the due date and the action to take.

Exposure, from the group to the worker

Similar exposure groups carry the representative noise measurement and the action level as recorded data. Each worker's exposure timeline is read from the positions held, so enrollment follows exposure.

  • The measurement in force for each group, with the source document attached. 1910.95(c)(1), (d)
  • What the group requires: hearing protectors from your own catalog, training and exams.
  • One timeline per worker and employer: position, group, measurement and the protectors issued.
Exposure timeline of a fictitious worker from 2019 to today: press operator in the Stamping group; the group's measurement, an 8-hour TWA of 83.0 dB below the action level and then 87.5 dB at or above it; two other hazards; and what the group requires, earplugs and training, with the periods covered by a record and the gaps without one.

A report anyone can verify

Each test report is stored as an immutable document with a SHA-256 hash. The QR code on the page opens a public check that confirms the document without showing the test or the name of the worker.

  • The check says whether a newer version exists, so an old paper is not mistaken for the current one.
  • Correcting a report creates a new version with the reason. The earlier one is kept.
  • The signature is applied to the hash of the document the professional opened.

Also in the record

Audiometers, calibration and test rooms
The state of the calibration is evaluated on the date of the test, and the room is checked against Table D-1. 1910.95(h); Appendices C, D and E
Employer structure
Units, departments and positions per employer. Renames are dated, so a report shows the name in use on the day of the test.
Clinics with several units
Records are readable across the company, added from any unit, and changed only by the unit that created them.
English, Spanish and Portuguese
Three languages in the interface, with the same record underneath.

Who it is for

  • Occupational health clinics

    You test for many employer clients. Each client has its own program, structure and exposure groups, kept apart from the others.

  • Mobile audiometric testing providers

    You test on site. The audiometer, its calibration and the test room go with every record, and the queue of the day tells you who is next.

  • Employers with an in-house program

    You need the due list, the notification to the employee and the OSHA 300 decision in one place, with the dates.

  • Industrial hygienists

    You define the exposure groups and the representative measurements that decide who is in the program.

Security and compliance, stated plainly

HCP Expert is designed to support the obligations of a covered entity or business associate under HIPAA. We make no certification claim. What follows is what the software does today.

  • Rules from the official text

    Normative tables, Appendix F included, are generated from the official eCFR text, and the source is kept with its hash. Nothing normative is typed in by hand.

  • Two-factor sign-in for everyone

    Every account needs a second factor besides the password: a passkey, a security key or an authenticator app. There is no way to opt out, and SMS or e-mail codes are not offered.

  • Append-only audit trail

    Audit events are never updated or deleted. Each one is chained by hash to the one before it, so tampering can be detected.

  • Access to health information is logged

    Each access to protected health information is written to the audit trail with the user, the record and the time.

  • No PHI sent to third parties

    Outbound connections pass through a single gate that allows only listed destinations. No protected health information leaves for third-party services.

  • Roles per organization, data per customer

    Permissions are granted by role in each organization and checked on every request. Data is isolated per customer at the database level.

This website sets no cookies and loads no trackers, third-party scripts or external fonts.
