Title: 50th Jubilee Winter School on Wave and Quantum Acoustics XLIXth Winter School on Environmental Acoustics and Vibroacoustics Szczyrk, Poland, 28 February – 3/4 March, 2022
Abstract: On behalf of Upper Silesian Division of the Polish Acoustical Society (main organizer) and Committee of Acoustics of the Polish Academy of Sciences (coorganizers) we are pleased to announce that according to many years of tradition the above-mentioned Conferences known as "Winter Schools" have been organized and carried out.50th Jubilee Winter School on Wave and Quantum Acoustics constituted platforms for sharing the results and achievements obtained in different branches of physical acoustics (e.g.molecular acoustics, relaxation processes, quantum acoustics, acousto-optics, magnetoacoustics, photoacoustics, acoustics of solid state, acoustic emission etc.).Conference consisted of 17th Workshop on Acoustoelectronics and 17th Workshop on Molecular Acoustics, Relaxation and Calorimetric Methods.XLVIXth Winter School on Environmental Acoustics and Vibroacoustics was the forum for all environmental and vibroacoustics fields.Particularly it concerned traffic noise, vibroacoustics of machines, room acoustics, building acoustics, noise protection and similar problems.
