GRAS Launches New Automotive Acoustic Test Device AutoKEMAR to Enhance Realism in Cabin Audio Evaluation

Acoustic equipment manufacturer GRAS Sound & Vibration has recently launched the 45BD AutoKEMAR globally—a next-generation Head and Torso Simulator (HATS) specifically designed for in-vehicle cabin acoustic testing. The device captures sound data from actual listener positions within real vehicle interiors, delivering high realism and test repeatability to meet the growing demand from OEMs, Tier 1 suppliers, and laboratories for premium cabin acoustic performance. As electric vehicles become more prevalent and intelligent cabins continue to evolve, the AutoKEMAR supports critical applications such as audio tuning, speech intelligibility, hands-free communication, NVH (Noise, Vibration, and Harshness), and wind tunnel testing—enabling engineers to optimize acoustic experiences based on data that closely reflects real-world user perception.
