Why It Matters
Hearing Loss Is Permanent. Testing Is Prevention.
Noise-induced hearing loss is 100% preventable but 100% irreversible. Beyond the human cost, undetected hearing loss drives workers' comp claims averaging $45K+, increases insurance premiums, impacts EMR scores, and creates long-term civil liability exposure. Audiometric testing is the early warning system that catches threshold shifts before they become permanent, recordable injuries.

The Cost of Not Testing
Annual audiometric testing catches threshold shifts early - when intervention can prevent further damage, before hearing loss becomes a recordable OSHA injury and a workers' compensation claim. A single occupational hearing loss workers' comp claim averages $30,000–$75,000. A well-documented audiometric testing program is your strongest legal defense.

The Invisible Booth™
How Boothless Testing Actually Works
OSHA doesn't require a sound booth - they require that ambient noise doesn't interfere with testing. The Invisible Booth™ monitors and documents environmental conditions in real-time, providing continuous compliance verification that a booth alone cannot.
Continuous Monitoring
Calibrated microphone measures ambient noise throughout the entire test
ANSI S3.1 Validated
Room noise compared against maximum permissible levels in real-time
Automatic Pause & Resume
Test pauses instantly when noise exceeds safe limits, resumes when clear
Documented & Stored
Ambient noise conditions permanently recorded with every audiogram
Independent Compliance Audit - Scott Ketcham
Scott Ketcham, one of the nation's leading occupational audiologists, conducted an independent audit of Soundtrace's testing methodology. His review validated that the Invisible Booth™ approach meets both OSHA 29 CFR 1910.95 and ANSI S3.1 standards - providing third-party credibility that goes beyond any manufacturer's self-certification.
The Testing Process
A 6-Minute Test. A Complete Clinical Workflow.
Every audiometric test flows through a clinically supervised workflow - with Soundtrace acting as your professional supervisor at every step.
Pre-Test Questionnaire
~1 min
Digital health history, noise exposure, and medications - captured before the test begins.
Digital health questionnaire captures noise exposure history, recent loud noise events, medical conditions, and any ototoxic medications. Responses are stored with the audiogram for clinical context.Automated Hearing Test
~4 min
All standard frequencies tested with calibrated headphones. Room noise monitored continuously.
The system tests hearing at all standard frequencies using calibrated audiometric headphones with automated threshold detection. Room noise is monitored continuously throughout to ensure accurate results.Hearing Change Detection
Instant
Results compared against baseline the moment the test completes. Shifts flagged automatically.
The moment the test completes, the system compares results against the employee's baseline. Meaningful shifts are flagged automatically with and without age adjustments. No waiting for someone to review paper records manually.Acknowledge & E-Sign
~1 min
Employee reviews results, signs digitally, and walks away. Records stored 30+ years.
Results are immediately available. The employee reviews their audiogram, acknowledges receipt, and e-signs - all before leaving the testing station. Every test, room noise level, and calibration record is stored digitally with 30+ year retention.Audiologist Review
Within 24 hrsEvery audiogram routed to a licensed audiologist. Shifts prioritized, findings annotated, follow-up recommended - all within 24 hours.
Behind the scenes, Soundtrace - acting as the professional supervisor for your hearing conservation program - routes every audiogram to a licensed audiologist for asynchronous review. Concerning results like hearing shifts, unusual patterns, or significant changes are prioritized. The audiologist annotates findings, confirms or revises STS determinations, and recommends follow-up - all within 24 hours, without disrupting the employee's workday.HPD Fit Testing
~2 minMeasure actual earplug protection per employee - the best way to train proper insertion.
For the most complete hearing conservation workflow, add quantitative HPD fit testing. Measure the actual protection each employee gets from their hearing protection device - the most effective way to train proper earplug insertion and verify real-world attenuation. Can be performed right after the audiometric test while the employee is already at the testing station.Key Advantages
Testing That Works Around Your Operations
Not the other way around. Test any employee, any shift, any day - with full OSHA compliance and automatic documentation.
6-Minute In-House Testing
Complete OSHA-compliant audiometric testing in about 6 minutes per employee, right at your facility. No off-site travel. No mobile van scheduling. No pulling workers from the floor for hours. Test during onboarding, any shift, any day - whenever it fits your operations.
OSHA-Compliant Without a Sound Booth
The Invisible Booth™ uses a built-in calibrated microphone to monitor room noise in real-time throughout every test. If the room gets too loud, the test auto-pauses. Room noise levels are stored with every hearing test - providing the same documentation a traditional sound booth would.
Catch Hearing Changes Before They're Permanent
The system automatically flags meaningful hearing shifts by comparing each annual test against the employee's baseline. Age-related adjustments are applied automatically. Changes are caught immediately - not weeks later when someone reviews paper records. Early detection means early intervention, before hearing loss becomes permanent and recordable.
Backed by Real Audiologists - and Independently Verified
Every hearing test is reviewed by a licensed audiologist within the platform. An independent audit by Scott Ketcham, one of the nation's leading occupational audiologists, validated that Soundtrace's testing methodology meets OSHA and ANSI standards. Dr. Subinoy Das, Soundtrace's Chief Medical Officer, oversees clinical protocols and ensures testing quality across the nationwide audiologist network.

Common Concerns
What EHS Teams Ask Us Most
Switching to in-house audiometric testing is a big decision. Here are the concerns that come up most - and honest answers.
Is boothless testing really OSHA-compliant?
Yes. OSHA doesn't require a sound booth - it requires that background noise doesn't interfere with testing accuracy. The Invisible Booth™ monitors room noise continuously using a calibrated microphone. If the room gets too loud for accurate testing, the test auto-pauses. An independent compliance review by Scott Ketcham - former OSHA enforcement leadership - confirmed that Soundtrace's methodology meets OSHA and ANSI standards. Additionally, Soundtrace performed an independent field accuracy study across 6,000+ audiograms and found accuracy levels to be consistent with traditional booth-based testing.
We don't have time to pull employees off the floor.
That's exactly why Soundtrace works. Each test takes about 6 minutes. You test a few employees at a time during shift changes, slow periods, or onboarding - not everyone on the same day. There's no van to coordinate, no clinic appointments, and no pulling your entire crew off the floor. Most clients tell us the operational impact is basically zero compared to mobile van days that disrupt an entire shift.
Our team isn't certified - who runs the tests?
Any member of your safety or occupational health team can do it. Soundtrace provides training and certification as the OSHA Professional Supervisor. Training and oversight verification takes about 45 minutes and can be done live virtually. The automated testing system handles the audiometric protocol - your technician manages the process and the employee experience. For organizations that prefer a fully managed approach, Soundtrace's growing network of certified service partners can come to your site and handle everything.
Why does hearing testing matter beyond compliance?
Noise-induced hearing loss is permanent and irreversible. By the time a worker notices they can't hear conversations clearly, significant damage has already occurred. Annual testing catches hearing changes early - while the damage is still minimal and intervention (better hearing protection, noise reduction, medical referral) can prevent further loss. Without testing, you won't know until it's a recordable injury and a workers' comp claim.
What about data security for employee health records?
Soundtrace is SOC 2 Type II certified and HIPAA compliant. All audiometric data - protected health information - is encrypted at rest (AES-256) and in transit (TLS 1.3). We maintain strict role-based access controls, complete audit trails logging every access, and continuous third-party security monitoring through Vanta. Your employees' health data gets the same level of protection as their medical records at a hospital.
