Mobile Occupational Hearing Testing

Factories need annual hearing tests brought to the parking lot

Bottom line

Worth studying, but do not buy without strong local proof.

Mobile occupational hearing testing businesses bring audiometric testing booths or vans to manufacturers, construction firms, airports, utilities, mines, and other noisy workplaces. OSHA hearing-conservation rules require programs when workers are exposed to 85 dB averaged over an eight-hour shift, which creates repeat annual testing, training, and recordkeeping demand.

How It Works

A mobile unit visits worksites, performs baseline and annual audiograms, checks calibration, flags threshold shifts, trains employees, and sends compliance reports to safety managers. Revenue comes from per-employee testing, noise surveys, annual contracts, hearing protector fit checks, and safety training add-ons.
