Cost:

30,00 € (including beverage)

Course Information:

The Transfer Path Analysis (TPA) is a test-based method to investigate the propagation of mechanical vibration, including the contribution of sound sources, in complex structures. Various different approaches have already been implemented with the commercialization of the TPA. These are available as out-of-the-box product. Nevertheless, it seems rather difficult to find the right approach for the understanding of a structure-borne phenomenon as the differences between the various concepts are usually not really visible. The aim of this course is to provide a basic understanding of the general idea of the TPA in the first place. Furthermore, various approaches from the three TPA categories, namely classical, component-based and transmissibility-based, will be illustrated and explained based on a wide range of application examples.

Learning Outcomes:
  • Understand the concept of the TPA and its importance to solve vibroacoustic tasks in both the R&D and the troubleshooting
  • Learn more about the propagation of sound and vibration in complex mechanical structures
  • Understand which TPA methodology should be applied for the requirements of dedicated applications and the difference between the various TPA variants
Instructors:

Dr.-Ing. Dejan Arsić received his diploma in 2004, followed by his doctoral degree in 2010 for his studies in audiovisual signal processing with focus on object tracking and behavioral analysis at the faculty of electrical engineering at Technische Universität München (TUM). He currently applies his profound knowledge in signal analysis as key account manager of Müller-BBM VibroAkustik Systeme in both the automotive industry and the wind energy industry. Here, he establishes elaborate solutions for various problems in the NVH field applicable in both the R&D and production processes.
Dr.-Ing. Arsić has (co-)authored more than 50 publications in books, journals and conference proceedings, and is reviewer for a range of leading scientific journals.

Dr. Dennis de Klerk studied Mechanical Engineering at the Delft University of Technology in the Netherlands. After his Master degree he pursuit a PhD at BMW Munich studying TPA Methods, Operational System Identification and Experimental Dynamic Substructuring (exp. DS). Finishing in 2008, he started a Müller-BBM VibroAkustik Systeme subsidiary in Holland serving customers in BeNeLux and UK. He furthermore obtained a  part-time assistant professor position at the Delft University of Technology during the same period, and is still mainly studying TPA and exp. DS methods.

Course C: Methods and Tools for Sound Design – Applications of Psychoacoustics

Day / time:

August 21, 2016, 12 am - 4 pm

Room:

Please ask for the room at the registration desk

Cost:

30,00 €

Course Information:

The acoustical quality of products such as automobiles, office equipment, or household devices, etc. is becoming more and more important: Product sound influences the purchase decision of the potential customer. That’s why sound design is crucial during the product design process and for the improvement of the acoustical features. Since established physical quantities, such as the A-weighted sound pressure level, do not sufficiently describe sound perception, the psychoacoustical approach may help to optimize the sound.

The four hour short course provides an introduction to psychoacoustics as well as an overview of applications. The course covers the current status of standardization of psychoacoustic parameters and emphasizes on advanced tools like Relative Approach Analysis, Hearing Model Analyses and High-resolution Spectral Analysis. The course is intended to familiarize the participants with jury testing methods, sound quality metric development and target sound determination.

Learning Objectives:
  • Basic expertise of psychoacoustics
  • Status quo of standardization of psychoacoustic parameters
  • Fundamental knowledge about advanced psychoacoustic tools
  • Insight into jury testing methods, sound quality metric development and target sound determination
Instructors:

Dr. André Fiebig / Dr. Roland Sottek, HEAD acoustics GmbH

In this introductory course, the Microflown particle velocity sensor and its characteristics will be explored, together with a wide range of applications and measurement techniques. A theoretical and practical comparison of velocity methods will also be made for the more traditional pressure-based measurement techniques.

Sound source localization is an important topic in the field of sound & vibration and product development. A particle velocity noise map is a useful tool to analyze noise sources, making systems based on the Microflown sensor very well suited for sound & vibration applications.  Approaches and solutions for stationary and non-stationary sound environments, covering all possible working scenarios, will be presented.
