The OROS Transfer Path Analysis (TPA) software is a comprehensive solution for experimentally determining and ranking the contributions of noise and vibration sources and their transmission paths to a target location, such as a passenger’s ear in a vehicle. The system integrates high-end data acquisition, advanced ATPA algorithms (developed with ICR), and flexible analysis tools to support NVH (Noise, Vibration, and Harshness) optimization across automotive, aerospace, marine, rail, and building applications. The software enables efficient, real-time acquisition of large channel counts, automated spectra sequencing, and does not require mechanical isolation of sources, simplifying the testing process. It provides structure-borne and airborne path separation, contribution validation, and synthesis calculations for scenario simulation. The solution is suitable for both R&D and troubleshooting, offering portable and distributed measurement capabilities, and is designed to reduce testing time while delivering actionable insights for acoustic comfort improvements.
