The second volume of Vibro-Acoustics includes eight chapters. As in the first volume, each chapter ends with a number of problems. The solutions are given in a separate volume, which also contains a summary of some of the most important governing equations from the first two volumes.A number of measurement results are presented in Volume II. Most of these measurements could not have been performed without the expert help of Fritiof Torstensson and Arne Jagenas at Chalmers, Knut Ulvund at DNV and Kent Lindgren and Danilo Prilovic at KTH. I also gratefully acknowledge the pioneering work by Prof T.Kihlman, who introduced the field of vibro-acoustics in Scandinavia.I would like to express my gratitude to Hector Valenzuela, Edoardo Piana and in particular to Benedetta Grassi for their untiring and very efficient work on preparing all the figures.Any comments or questions on the text are most welcome.
