Practical NVH Signal Processing Methods C0431

Topics: Quality, Safety & Maintenance

Signal processing has become a critical tool in optimizing vehicle noise. This seminar will help you to understand the foundation common to all NVH data acquisition equipment including digitizing, windows, aliasing, averaging techniques, and common analysis functions such as the power spectrum, transfer function and coherence. Fundamental concepts such as filtering, modulation, convolution, and correlation, as well as specialized techniques used in rotating machinery such as adaptive re-sampling and order tracking, will be covered. The seminar will also cover multi-input multi-output (MIMO) signal processing, array based solutions for force identification, source and path characterization and data visualization. Brief introductions to emerging concepts will also be explored and computer demonstrations, physical experiments and case studies will be used to illustrate applied, real-world problems.

Learning Objectives

By attending this seminar, you will be able to:

  • Explain the fundamental controls typical in modern spectrum analysis tools
  • Interpret NVH data and judge its relevance to physical phenomena
  • Extract new types of useful information from NVH data
  • Implement new signal processing techniques

Who Should Attend

NVH technicians, engineers and managers who want to understand how NVH data is produced and interpreted will find this seminar valuable. The material is presented at a level suitable for beginners, but offers the more experienced practitioners new insight into the concepts presented through the illustrations and demonstrations that are included.


The majority of the course material is presented through qualitative descriptions, practical examples, illustrations and demonstrations, which require only basic mathematical skills. However, some familiarity with time and frequency domain measurements, linear algebra and statistics will enhance overall understanding of the material.
