Engineering Acoustics



His current research is concentrated on a few main themes. The first concerns characterization of sources of sound and vibration. The underlying rationale is that irrespective of the aim of, and the approach for, an analysis of an acoustic or structural dynamics problem, conclusions cannot be drawn without physically correct descriptions of the source and thorough understanding of source mechanisms. The second theme relates to the interplay between deterministic and statistical or asymptotic field representations and concerns the size of the physical domain, which must be included in the analysis of structure-borne sound and vibration problems in order to achieve proper descriptions. The third theme addresses the structural acoustics features of composite and sandwich systems. A substitution of homogeneous, isotropic and linearly elastic material by composites or sandwich configurations requires modified design philosophies. The associated structural acoustic consequences are presently insufficiently treated which cause complex and costly problems for industry and society. Actively controlled constitutents, moreover, establishes a new branch of the theme. The fourth focuses on vibration control by design and aims at developing manageable procedures for acoustic and structural dynamic design. Based on experience from co-operation with industry, design procedures should comprise two principal ingredients; an adequate representation of the process to give the necessary understanding of the physics involved and the tool to perform the predictions. As such this theme integrates the findings and results of the two aforementioned. Also, for some specific applications, computerised design procedures have been developed and proven powerful in engineering practice.


Career Summary


Professor Petersson succeded late Prof. M. Heckl in September 2000 at Institut für Technische Akustik, Technische Universität Berlin. Since his doctorate degree at Chalmers University of Technology, he has continued to specialise in acoustics and structural dynamics with his research having applications in most branches of technology. Professor Petersson has had an international academic career involving supervision and management of more than twenty long-term research projects. He has also participated in and co-ordinated research exchanges within the European Union and has served on international standards working groups. His publication list comprises more than 175 authored and co-authored papers and reports. Recently, he managed and was principal investigator of a long-term research programme at the Institute of Applied Physics-TU Delft, concerning vibroacoustic transmission in complex structures. Between 1984 and 1994 Prof. Petersson has held positions at the Danisch Technical University, at Lund Institute of Technology, at Liverpool University, at Institute of Applied Physics-TU Delft and at Royal Institute of Technology. He has now joined ITA TUB from a previous Chair at Loughborough University, UK.
