The Reality on the Floor
Why Traditional Testing Fails in Transportation Equipment Manufacturing
The sheer scale of operations - 811 companies, tens of thousands of workers per plant - makes annual van visits a logistical impossibility.
Stamping, Welding, and Assembly Line Noise
Metal stamping presses produce impulse noise exceeding 110 dBA. Robotic welding, riveting, and assembly operations create sustained exposure across multiple shifts.
Massive Workforce Across Multi-Plant Operations
811 companies and hundreds of thousands of workers. Scheduling annual audiometric testing for plants running 2–3 shifts requires a system that scales without van bottlenecks.
OEM Quality Standards Add Compliance Pressure
Tier 1 and Tier 2 suppliers face OEM quality audits alongside OSHA inspections. Gaps in worker health documentation become supply chain risk findings.
11,892 Hearing Loss Cases in 9 Years
The highest case volume of any industry in this analysis. Despite a relatively low 0.31% rate, the absolute number of cases means significant workers' compensation exposure.

How Soundtrace Fits Into Transportation Equipment Manufacturing
Test Between Shifts at Scale
6 min
per test
6-minute audiometric tests during shift changes. Test thousands of workers per plant without pulling anyone off the production floor.
Track Every Worker Across Lines
Per
worker tracking
Personal dosimetry tied to each worker's actual exposure across stamping, paint, body, and assembly operations.
Verify HPD for Impulse Noise Environments
Real
NRR verification
Fit testing confirms actual attenuation for workers near stamping presses and impact operations where peak levels exceed 140 dB.
Multi-Plant Compliance Dashboard
30+
year retention
Centralized records across all facilities. Know which plants have overdue audiograms, unresolved STS flags, and HPD compliance gaps.
Know Your Exposure
Typical Noise Levels in Transportation Equipment Plants
Stamping operations routinely exceed 100 dBA with impulse peaks above 140 dB. Even downstream assembly areas often surpass the action level.

Compliance Context
Scale-Level Compliance in Transportation Equipment
The highest hearing loss case volume in U.S. manufacturing demands systematic, scalable compliance infrastructure.
OSHA 29 CFR 1910.95
Full hearing conservation program for all production workers. Multi-plant operations require standardized testing across every facility.
OEM Supplier Audits
Tier 1 and Tier 2 suppliers face customer quality audits that review worker safety documentation. HCP gaps become supply chain risk.
Impulse Noise Documentation
Stamping press peaks above 140 dB require documented dual HPD programs and continuous monitoring - not annual snapshots.
