Traditionally I invite you to acquaint with the preliminary list of lectures and some abstracts of lectures submitted for presentation in the 39th Winter School on Vibroacoustical Hazards Suppressions. This national School, organized by Upper Silesian Division of the Polish Acoustical Society and Institute of Physics at the Silesian University of Technology, is planned this year at the turn of February and March 2011. This conference is organized in different places of Silesian Beskidy Mountains, but this year will be again organized in Szczyrk.
