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 module focuses on how to collect and process NVH data. You’ll learn how sensors and data systems capture vibration and sound signals, and how to clean and analyze them using basic signal processing methods like FFT and filtering. We’ll also use a free tool, REW (Room EQ Wizard), to visualize and understand NVH signals.

In this final module, you’ll learn how to assess and improve product sound and feel. You’ll explore how engineers rate sound quality and find vibration issues, then use methods like damping and isolation to fix them. You’ll also see how before-and-after testing confirms the success of NVH improvements.

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.
Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
