Fundamentals of Vibration and Sound
Sunday, June 9
Time: 8:00 AM - 5:00 PM
Price: Full Day, $800 per student
Instructor: Stephen A Hambric, Hambric Acoustics

Have you been measuring or simulating vibration and sound without really having learned the fundamentals?  Drawing from my many tutorials in the Internoise congress proceedings (available at and the book ‘Engineering Vibroacoustics’ (Wiley) I will teach you the basics with a minimum of math and plenty of computational and experimental practical examples.  We’ll start with structural vibrations, where you will learn about different wavetypes, modes of vibration, mobility and impedance, infinite structure theory (one of your most useful tools!), and structural power flow.  Next, I’ll explain sound-structure interaction:  how structures radiate sound and how sound excites structures, sound power transmission loss, and coupling between structures and acoustic cavities.  Finally, I’ll give an overview of numerical methods (finite elements, boundary elements, statistical energy analysis) used to solve vibroacoustic problems and their frequency ranges of applicability.

  • Structural Vibrations
    • Longitudinal, shear, and bending waves in beams and simple, stiffened, and composite panels
    • Modes of vibration
    • Mobility and impedance
    • Infinite structure theory – one of your best friends!
    • Structural power flow between coupled oscillators – the basis of Statistical Energy Analysis
  • Sound-Structure Interaction
    • Basic loudspeaker sound radiation and the concept of radiation efficiency
    • How acoustic regions ‘load’ and couple with structural vibrations
    • How structural vibrations radiate sound

Active Noise Control [CANCELLED]
Sunday, June 9
Time: 8:00 AM - 12:00 PM
Price: Half-day, $400 per student
Instructor: Yangfan Liu, Assistant Professor of Mechanical Engineering, Purdue University

The history of active sound and vibration control technology can be dated back to its first documented attempt in the 1930s. Wave theory-based research on active control of sound and vibration started in 1950s. It first became a popular research area in 1990s, during that period, enormous studies were carried out, many effective active control signal processing algorithms were developed, and implementations were successful in a wide range of engineering applications, such as the control of noise in automobiles, aircraft, buildings, industrial environments, etc. After a one-decade “cooled-down” period, active sound and vibration control have recently reclaimed its research popularity. This is not only driven by the even wider range of application and commercialization potentials of this technology brought by the recent rocketing in the computing power of signal processing hardware together with its cost drop, but also by the unprecedented potential research outcomes if the recent research breakthroughs in other widely studied areas, such as artificial intelligence, computing technology, virtual reality, smart systems, perception-based engineering, etc., can find their ways in benefiting active control of sound and vibration.

This half-day short course introduces the fundamental concepts and theories related to active noise and vibration control, basic algorithms, as well as various typical applications of this technology.

Overview of Acoustic and Vibration Simulation Methods

Time: 8:00 AM - 5:00 PM
Price: Full day, $800 per student (may increase with lunch)
Instructors:    Dr. Rabah Hadjit, ESI Group and Dr. Satya Deshpande, ESI Group


Numerical Simulation has become an accepted and essential part of interior and exterior acoustics and vibration design for a range of industries and products and especially for the vehicle industry in order to allow effective early design and to complement and reduce the amount of testing involved in product development.  Well-established tools and modeling practices exist for several different simulation methods each of which has its own particular advantages and limitations based on frequency range, modeling objectives, and speed versus accuracy tradeoff and computer resource required.  This full-day course is intended to offer to the test engineer, minimally to moderately experienced simulation engineer or those wishing to have a deeper understanding of one or more of the presented analysis methods an introduction to these different modeling techniques with the goal of improving understanding of the best applications to current state-of-the art vehicle acoustic and vibration design processes.  The team of instructors offering significant acoustics and vibration simulation experience will present background, theory, practical application examples and discussion of several of the current state-of-art analysis useful methods listed in the agenda.
