Smart features, ultra-thin designs, and built-in DSP shape the future of vehicle testing

In Part 1, we looked at the transition toward 1/4” microphones, low-noise models for EVs, and rugged sensors built for harsh testing conditions. In this second part, we focus on cutting-edge features that enhance efficiency, reduce setup complexity, and support advanced automotive applications like CFD validation and in-cabin audio optimization.

In manufacturing, there’s one constant: pressure. Pressure to scale. To cut downtime. To maintain consistent quality across global lines.

For those involved in end-of-line testing—whether on the engineering or procurement side—acoustic validation is just one piece of the puzzle, but a crucial one. 

What often gets overlooked is how the test equipment itself can either simplify your process or introduce unnecessary friction. 

Axiometrix Solutions provides cutting-edge test and measurement solutions through its globally respected brands, Audio Precision, GRAS Sound & Vibration, and imc Test & Measurement. Unified under the Axiometrix Solutions banner, they offer one-stop solutions for all automotive testing needs, helping manufacturers and engineers avoid the costs and complications arising from fragmented systems and vendor management.

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 Until now, they’ve had to rely on DIY rigs, ad hoc configurations, or outdated tools that don’t match the sophistication of today’s vehicles.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.
