Explainer-Diagnosing and Curing Automotive Interior Trim Noise

Imagine sinking into the driver seat of a premium electric vehicle only to have the experience ruined by a persistent, high-pitched squeak from the dashboard. In the era of silent EVs, automakers can no longer rely on loud internal combustion engines to mask manufacturing flaws. Engineering absolute interior silence has become a mandatory metric for market success and brand reputation. 🚗

In this video, we go behind the scenes of automotive acoustic engineering to see how manufacturers hunt down every rattle and squeak. We break down the difference between macroscopic kinetic energy in loose parts and the microscopic friction events known as stick-slip. You will see how engineers use massive anechoic chambers and full-vehicle shakers to replicate the world’s roughest roads, from cobblestone streets to deep potholes. 🛠️

We also explore the fascinating world of tribology and material compatibility. From testing raw plastic samples on specialized flexure-based benches to applying advanced anti-friction coatings, car makers go to extreme lengths to ensure a quiet ride. Learn how micro-engineered surface textures and chemical additives are replacing traditional felt tapes to create the ultimate premium driving experience. 🤫 Find out more about our Antifriction Coatings, which were created to help automotive professionals eliminate interior trim noise.
