Noise, Vibration & Harshness (NVH) Testing

Have you ever noticed how a luxury car door ""thuds"" smoothly while a cheaper one ""clangs,"" or why some electric motors hum pleasantly while others are irritating? These experiences are the result of precise Noise, Vibration, and Harshness (NVH) engineering. NVH performance defines how a product sounds, feels, and conveys quality across industries like automotive, aerospace, and consumer electronics. In this course, you’ll gain a hands-on understanding of NVH testing, data acquisition, and signal processing using accessible, free tools. You’ll learn how engineers capture vibration and sound data, analyze signals, and apply techniques to improve product comfort and acoustic performance. Designed for aspiring NVH engineers and mechanical professionals, this course blends theory with real-world applications. This course is designed for engineers working on mechanical, automotive, or acoustic performance, as well as R&D, quality professionals, and students who want practical NVH analysis skills. Learners should be familiar with a basic understanding of mechanical vibrations, acoustics, and familiarity with using measurement software or Excel for data analysis. By the end, you’ll be able to measure and interpret NVH data, identify noise and vibration sources, and suggest improvement strategies. You’ll also gain practical experience with Room EQ Wizard (REW), preparing you for real-world testing and optimization challenges. Whether entering NVH engineering or enhancing your mechanical design skills, this course lays the foundation to transform unwanted noise into engineered perfection."
