NVH Testing Fundamentals: Noise, Vibration, and Harshness Engineering

Why do some products feel premium and silent, while others rattle and buzz? Understanding Noise, Vibration, and Harshness (NVH) is key to designing high-quality products, especially in the rapidly evolving automotive and electric vehicle sectors. This text-based course guides you through the fundamental principles of NVH engineering, from basic acoustic theory to modern data acquisition techniques. You will learn how to identify noise sources, analyze vibrational behavior, and interpret test data to improve product refinement. What you'll learn: Understand the foundational physics of sound, vibration, and human perception; Identify key NVH measurement hardware, including accelerometers, microphones, and data acquisition systems; Apply signal processing techniques such as Fourier transforms and frequency analysis to raw test data; Analyze unique NVH challenges in modern electric vehicles, such as high-frequency motor whine and wind noise; Evaluate structural dynamics and transfer paths to isolate and mitigate unwanted noise; Practice interpreting real-world NVH test scenarios through written engineering case studies. The course starts with essential terminology and fundamental acoustic concepts before moving into practical measurement strategies, sensor placement, and modern digital signal analysis techniques. Designed for entry-level engineers, product designers, and technical enthusiasts with no prior background in NVH testing.
