The ascent of electric vehicles (EVs) marks a monumental shift toward sustainability and innovation. But the transition amplifies a challenge that was once overshadowed by the rumble of internal combustion engines (ICEs): road and tire noise. In the age of EVs, understanding and mitigating these noise sources has become more crucial than ever. In this blog post, we delve into the significance of road and tire noise testing in EVs, highlighting why it's a pivotal aspect of automotive engineering and design.

The founder of GRAS Sound & Vibration, the renowned acoustical engineer Gunnar Rasmussen, passed away on the 17th of April 2024.

GRAS Sound & Vibration has always been known as a development and knowledge centre, constantly evolving and always up to date with trends and needs in the market thanks to close collaboration with our customers.

The rapid integration of advanced technologies in consumer audio products is changing the industry on a day-to-day basis. New features like Active Noise Cancelling, Hybrid Noise Cancelling, and voice-controlled smart systems are hardy considered premium options anymore, but simply what customers have come to expect. This directly impacts audio testing on production lines, where precise measurements to ensure sound quality are more vital than ever. This demand applies to mid- and low-end products, too, leading to increased production line costs and potentially strained relationships between contract manufacturers and audio brands. To successfully adapt to this trend, both electronics manufacturers and test microphone manufacturers need to embrace customized measuring products and solutions as the way forward. In GRAS Sound & Vibration, we have successfully adopted customization as a core principle driving product development and innovation.
