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."
In this module, you’ll learn the basics of Noise, Vibration, and Harshness (NVH). You’ll explore what causes NVH in machines and vehicles and why it matters for comfort and product quality. You’ll also understand how NVH is measured and how human perception affects the way we judge sound and vibration.

Détails du module
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.

’Lorsque j'ai besoin de cours sur des sujets que mon université ne propose pas, Coursera est l'un des meilleurs endroits où se rendre.’
Chaitanya A.
’Apprendre, ce n'est pas seulement s'améliorer dans son travail : c'est bien plus que cela. Coursera me permet d'apprendre sans limites.’
When will I have access to the lectures and assignments?
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.
What will I get if I purchase the Certificate?
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.
Is financial aid available?
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.
