Foster Instruments delivers on-site audiometric testing to Indiana manufacturers, steelmakers, RV builders, and warehouses. CAOHC-certified technicians arrive with the mobile booth, audiometer, and OSHA-ready paperwork.
Built for Indiana’s Industrial Workforce
Indiana leads the nation in steel production, RV manufacturing, and auto-component output. Every one of those operations has workers exposed above the OSHA 85 dBA action level. Foster brings the audiometric booth, the technician, and the compliant paperwork to your facility — your Indiana team never has to travel to a clinic again.
We regularly serve facilities in Indianapolis, Fort Wayne, Evansville, South Bend, Gary, Hammond, Bloomington, Lafayette, Muncie, Anderson, Terre Haute, Kokomo, Elkhart, and Columbus, IN.
