HOLTE, DENMARK, March 18, 2026. GRAS Sound & Vibration proudly announces the global launch of the GRAS 45BD AutoKEMAR, a next-generation Head & Torso Simulator (HATS) designed specifically for automotive in-cabin acoustic testing. 

AutoKEMAR sets a new benchmark for realism, flexibility, and repeatability in vehicle sound measurements, supporting automotive OEMs, Tier 1 suppliers, and test laboratories in meeting the growing demand for high-quality in-cabin acoustic performance. 

“In-cabin sound today is judged by what people perceive, not just what instruments record,” says Santiago Rayes, Product Manager at GRAS Sound & Vibration. “With AutoKEMAR, we set out to capture sound from a realistic listening position inside real vehicle interiors, so engineers can make decisions based on data that truly reflects the occupant experience—without sacrificing repeatability.”

Designed for the Realities of Modern Vehicles

As vehicles become quieter, more electric, and more digitally connected, in-cabin acoustics have become a defining element of brand identity and user experience. Engineers must accurately measure:

• Audio system performance & tuning
• Sound Quality & Sound Design
• Infotainment and DSP testing
• Speech intelligibility and voice quality
• Hands-free communication
• In-cabin NVH
• Wind tunnel measurements

The GRAS 45BD AutoKEMAR is purpose-built to address these challenges with unmatched realism.

Built on the Legacy of KEMAR — Reimagined for Automotive

Based on the original GRAS KEMAR platform, the AutoKEMAR introduces a fully redesigned automotive-focused architecture including:

• Widest and most flexible positioning capabilities in the market
• User-reconfigurable system – one unit supports multiple applications
• ISOFIX-compatible seat mount for secure and repeatable installation
• Rattle-free design enabling reliable on-road testing
• Adjustable height, seat distance, tilt, rotation, and viewing angle
• Coverage of the full ear ellipse and beyond
• Optional integrated mouth simulator
• Low-noise configuration 

The result is a highly realistic human acoustic simulation tool that accurately represents the influence of the human body in the vehicle sound field.

“Engineers told us they needed a solution that could move naturally within the vehicle cabin while remaining stable and repeatable during testing,” Rayes adds. “AutoKEMAR combines realistic human acoustic simulation with exceptional positioning flexibility, making it suitable for everything from lab validation to real-world on-road measurements.”

Realistic Testing Where It Matters

Unlike microphone arrays that do not simulate human body influence, AutoKEMAR captures the true listening experience. It is optimized for automotive acoustic measurements in:

• Static lab setups
• Dynamometer tests
• Wind tunnel tests
• Real-world on-road testing

Its flexible seat mount and head positioning system allow engineers to simulate different driver sizes, seating positions, and viewing angles, making it the ideal solution for headrest speakers, spatial audio, and advanced driver interaction systems.

Supporting the Future of Mobility

The AutoKEMAR is not limited to traditional vehicles. It is equally suited for:

• Electric and hybrid vehicles
• eVTOL aircraft
• Trains and airplane cabins
• Consumer electronics applications where human acoustic influence matters

With the 45BD AutoKEMAR, GRAS expands its automotive solution portfolio and reinforces its commitment to precision, realism, and engineering excellence.
