Currently, no widely accepted measurement methodology exists for in-car RNC systems. Automotive OEMs, suppliers, and research institutions apply different procedures, measurement microphone configurations, driving conditions, and performance metrics, making it difficult to compare system performance across vehicles, development teams, and research studies. In response to this situation, the NVH And Sound (NAS) Technical Subcommittee under TCAA established a dedicated Work Group to look into developing a common measurement and evaluation framework for in-car RNC systems.
