Frequently Asked Questions

A hearing conservation program is an OSHA-mandated workplace safety system designed to protect employees exposed to hazardous noise levels. It encompasses noise monitoring, annual audiometric testing, hearing protection fit testing, employee training, and recordkeeping. Companies need one to maintain regulatory compliance, prevent irreversible occupational hearing loss, and reduce long-term workers' compensation liability. Industries from food production to aerospace & defense are required to comply when noise exceeds OSHA thresholds.

OSHA requires employers to implement a hearing conservation program when workers are exposed to noise at or above an 8-hour time-weighted average (TWA) of 85 dBA. Key requirements include annual audiometric testing (audiograms), annual training on the effects of noise, provision and fit testing of hearing protection, ongoing noise exposure monitoring, and thorough recordkeeping. For a complete overview, visit our compliance hub or download the annual compliance checklist.

Any employer with workers exposed to an 8-hour TWA of 85 dBA or above must comply — this applies under OSHA 1910.95 for general industry and OSHA 1926.52 for construction. High-noise industries include food production, metals & fabrication, automotive parts manufacturing, oil, gas & petrochemical, lumber & wood products, concrete & aggregates, heavy equipment, and aerospace & defense. Browse all covered industries to see how Soundtrace supports each sector.

Non-compliance carries serious consequences: OSHA citations and fines up to $15,625 per violation per day, costly workers' compensation claims for occupational hearing loss, increased legal liability, and reputational damage. Most critically, employees suffer permanent, irreversible hearing loss. Research links untreated hearing loss to broader health risks — learn more in our white paper on hearing loss and health outcomes. Our ROI calculator shows the true cost of non-compliance versus investing in a compliant program.

If employees must raise their voices to be heard at arm's length, noise levels likely exceed OSHA's 85 dBA action level. The definitive way to know is to conduct workplace noise monitoring using calibrated dosimeters or sound level meters. Soundtrace integrates real-time noise monitoring with your audiometric testing program so you can track exposure data and determine compliance requirements in one system.

Yes — boothless audiometric testing is fully OSHA-compliant when ambient noise levels are controlled and ANSI S3.1 protocols are followed. Soundtrace ensures compliance through real-time ambient noise checks and calibrated equipment at every test frequency. Our proprietary Invisible Booth™ methodology records ambient noise data as proof of a valid test environment. Read our field booth validation white paper for the science behind it, or explore the full audiometric testing feature.

A Standard Threshold Shift (STS) is a change in hearing threshold of 10 dB or more, averaged across 2000, 3000, and 4000 Hz in either ear, relative to the baseline audiogram. OSHA requires employers to identify STS events and take follow-up action. Soundtrace automatically detects, flags, and tracks STS events through its audiometric testing platform, and all findings are reviewed by licensed audiologists. Proper recordkeeping of STS data is essential for compliance.

Yes. OSHA 1910.95 Appendix D sets maximum allowable ambient noise levels for testing environments but does not require a dedicated booth. Soundtrace's audiometer uses noise-attenuating headphones and records real-time ambient noise data at every frequency for every test — what we call the Invisible Booth™ methodology. This approach is validated in our field booth validation white paper and enables compliant testing anywhere, eliminating the need for mobile testing vans.

Yes. Soundtrace enables in-house, boothless audiometric testing using calibrated equipment, OSHA-compliant protocols, and automated recordkeeping — eliminating the need for expensive mobile van visits.

OSHA requires annual audiograms for all noise-exposed employees, with a baseline test within the first six months of employment in a noise-exposed role. Hearing protection fit testing should be performed at baseline and whenever new hearing protection is issued or if workers report difficulty with proper fit. Soundtrace streamlines both audiometric testing and fit testing into a single workflow, with automated scheduling and compliance recordkeeping.

Hearing protection fit testing measures how effectively earplugs attenuate noise for an individual worker. Soundtrace provides digital fit testing using PAR (Personal Attenuation Rating) scoring integrated directly into the audiometric testing workflow. After testing, each worker receives a personal attenuation score so you can verify adequate protection. Learn more about compliance requirements or schedule a demo to see fit testing in action.

The Noise Reduction Rating (NRR) on earplug packaging is measured under ideal laboratory conditions and significantly overstates real-world protection. OSHA's de-rating method cuts the NRR by 50% for estimating actual attenuation. The only way to verify what protection a specific worker actually receives is to conduct individual fit testing and obtain a Personal Attenuation Rating (PAR). Soundtrace integrates fit testing with audiometric testing for a complete worker protection profile.

The most effective approach is continuous, real-time noise monitoring using calibrated dosimeters placed on workers across shifts and areas. Soundtrace integrates noise exposure data with hearing test results and fit testing scores to give safety teams a complete picture of risk. This data feeds into compliance dashboards and automated recordkeeping. Request a quote to learn more.

OSHA 1910.95(k) requires annual hearing conservation training for all workers exposed at or above the 85 dBA action level. Training must cover the effects of noise on hearing, the purpose and proper use of hearing protectors, and the purpose of audiometric testing. Soundtrace includes built-in training modules that satisfy OSHA requirements and automatically track completion for recordkeeping. See our annual training page for details.

OSHA 1910.95(m) requires audiometric test records to be retained for the duration of the affected worker's employment. Industry best practices recommend retaining records for at least 30 years after employment ends. Soundtrace stores all records in a SOC 2-certified, HIPAA-compliant cloud platform with permanent retention through our automated recordkeeping system. Learn more about data protection on our security page, or review our data security white paper.
