While mobile audiometric testing vans offer convenience, there are significant hidden costs that safety managers often overlook when evaluating their hearing conservation program. Understanding the full cost picture — direct and indirect — is essential before committing to a vendor model for the long term.
Mobile van testing is typically priced at $45–$80 per employee per test, plus mobilization fees that range from $500 to over $2,000 depending on travel distance and facility requirements. For a facility with 100 enrolled employees tested annually, the direct testing cost alone is $5,000–$10,000 per year before any administrative overhead.
Scheduling complexity. OSHA requires each enrolled employee to be tested within 12 months of their prior test. Van scheduling works on fixed visit dates, which means employees hired between visits may wait nearly a year for their baseline. Employees who miss the testing day require individual follow-up arrangements. Turnover-intensive facilities may struggle to maintain clean annual cycles.
Result delays. Mobile van test results typically take 2–4 weeks to return from the vendor's review process. During this window, Standard Threshold Shifts go unidentified. The 21-day OSHA notification clock doesn't start until the professional supervisor completes review — meaning a shift identified 3 weeks after testing may have only days left in the notification window when the employer first learns about it.
Record control. In the mobile van model, audiometric records are held by the vendor. Accessing historical records for OSHA inspections, workers' compensation proceedings, or STS trend analysis requires vendor cooperation. When vendors change ownership, systems, or go out of business, record continuity is at risk.
Operational disruption. Van visits require pulling workers from production, managing queues, and coordinating with supervisors. The operational cost of a 100-person testing day — in lost productivity, supervisor time, and scheduling friction — can exceed the direct testing fee.
In-house automated audiometric testing eliminates all of these hidden costs. Testing happens on the employer's schedule, not the vendor's. Results are immediate. Records are employer-controlled. New hires can be baselined within days of starting in a noise-exposed role rather than waiting months for the next van visit.
Soundtrace's audiometric testing platform is designed for exactly this model: employer-side testing infrastructure with professional audiologist oversight built in, at a per-test cost that is a fraction of the mobile van alternative at scale.
