The new gold standard in in-cabin acoustic testing is here, and it offers precision, practicality, and repeatability.
Over the past few years, we’ve seen growing demand in the automotive industry for accurate, standardized methods of performing acoustical measurements inside the car cabin. Whether it’s performance testing, characterization or optimization of automotive audio systems, analysis of a vehicle’s NVH behavior, or general cabin acoustics benchmarking, engineers around the world have been searching for a reliable solution—one that is easy to set up and capable of delivering repeatable results quickly. Until now, they’ve had to rely on DIY rigs, ad hoc configurations, or outdated tools that don’t match the sophistication of today’s vehicles.
That’s why we created the GRAS AutoArray—our new 6-Microphone Array, built for automotive engineers who are ready to improve their workflow and test results reliability in their in-cabin acoustic testing.
Evolving tools and techniques in response to electrification and modern testing demands
In the dynamic world of automotive engineering, acoustic testing is rapidly evolving—especially with the shift toward electric vehicles (EVs). As noise sources change and test environments become more complex, the demand for precision, durability, and smarter tools is reshaping the field. In this two-part series, we explore the latest developments in automotive acoustic measurement technology.

Research shows that prolonged exposure to noise can negatively impact quality of life, contributing to stress, sleep disturbances, and decreased productivity. As a result, consumers are demanding quieter home environments, they expect high-performance products that maintain efficiency while minimizing background noise. This drives manufacturers to prioritize noise reduction in appliance design. However, meeting these expectations presents challenges for product development engineers, particularly as they balance noise control with other performance factors.
