ROI Calculation Logic

Assuming a medical facility conducts 2,500 objective hearing tests annually, this technology could reduce test time by 50%, saving approximately 1,000 technician hours per year. At an estimated labor cost of $20/hour (AI est.), this translates to ~$20K/year in cost savings (AI est.). Additionally, a 20% increase in test volume due to improved efficiency, at $13.50/case (AI est.) in reimbursement, could generate ~$65K/year in increased revenue (AI est.). Total estimated economic impact: ~$85K/year (AI est.).

Speed to Market
4× faster than in-house development
This technology is centered on brainwave signal measurement and analysis algorithms, with its technical foundation clearly detailed in the patent specification. By integrating the established signal segmentation and similarity calculation software modules into existing general-purpose EEG hardware, rapid productization is anticipated.
