I have a great pleasure to inform the "AA" Readers that the 39th Winter School on Wave and Quantum Acoustics, organized by Upper Silesian Division of the Polish Acoustical Society and Institute of Physics at Silesian University of Technology, is planned at the top of March 2010 in beautiful scenery of Silesian Beskidy Mountains. Many times it was organized in Wisła, Skoczów, Szczyrk, and Korbielów, and this year it will be organized again in Szczyrk.

As always, the School has been a place where achievements of various sections of physical acoustics (especially molecular acoustics, quantum acoustics, acousto-optics, magnetoacoustics, acoustoelectronics, photoacoustics, acoustics of solids etc.) are being exchanged. Moreover, some similar and related topics, for example optoelectronics and thermal wave methods, will be presented too.

As at previous years the School will be divided on three different, but complementary, parts - Winter Workshops (WW). Chronologically it will be: 6th WW on Acoustoelectronics (chairman Prof. Marian Urbanczyk, Silesian University of Technology, Gliwice), 6th WW on Molecular Acoustics, Relaxation and Calorimetric Methods (chairwoman Dr. Marzena Dzida, Silesian University of Technology, Katowice) and 15th WW on Photoacoustics and Thermal Waves Methods (chairman Prof. Jerzy Bodzenta, Silesian University of Technology, Gliwice). Moreover, this year we propose take participation in associated conference - the 4th conference on Integrated Optics - Sensors, Sensing Structures and Methods (chairman Prof. Tadeusz Pustelny, Silesian University of Technology, Gliwice).

Traditionally I invite you to acquaint with preliminary program and some abstracts of lectures submitted to presentation in 38th Winter School on Vibroacoustical Hazards Suppressions. This national School, organized by Upper Silesian Division of the Polish Acoustical Society and Institute of Physics at Silesian University of Technology, at this year is planned at the first week of March 2010. This conference is organized in different places of Silesian Beskidy Mountains, but this year it is organized in Szczyrk.

The conference is the forum for all environmental vibroacoustics fields. Particularly it concern to traffic noise, industry noise, vibroacoustics of machines, room acoustics, noise protection and similar problems. During the School the theoretical works, experimental, measuring, technical, applied and normative ones are presented.

The School lectures, and other conference materials, will be published in the "Materials of the XXXVIII Winter School on Vibroacoustical Hazards Suppressions" (in Polish) edited by Dr. Roman Bukowski and Dr. Mieczys?aw Roczniak (chairman of the conference). This publication is intend to participants of the School and for many libraries in Poland.

This national Seminar, with some foreign guests, in this year is organized by Upper Silesian Division of the Polish Acoustical Society, with cooperation of Institute of Physics - Science-Didactics Center at Silesian University of Technology and Acoustics Committee of Polish Academy of Sciences. In this year OSA'10 will take place in Gliwice at the Congress-Educational Center of the Silesian University of Technology. The conference has two famous honorary patrons - the Magnificence Rector of the Silesian University of Technology, Prof. Andrzej Karbownik, and Ministry of Science and Higher Education, Prof. Barbara Kudrycka. The Seminar is a forum for all fields of acoustics. Particularly in this year, in the Seminar Program you can find the following topics: general acoustics, environmental acoustic, biomedical acoustics, acoustics in blind person's life, active noise control, acoustical emission, vibroacoustics, ultrasound, interior acoustics and others. During the Seminar, the theoretical works, experimental, measuring, technical, applied and normative ones are presented.

Traditionally, the 42nd Winter School on Vibroacoustical Hazards Suppressions national conference is organized by Upper Silesian Division of the Polish Acoustical Society. The conference again is organized in Szczyrk. As at previous year, the conference has two co-organizers, i.e. Institute of Physics – Science-Didactic Center at the Silesian University of Technology and the Committee of Acoustics of the Polish Academy of Sciences. The conference is a forum for all environmental vibroacoustic fields. Particularly it concerns traffic noise, industry noise, vibroacoustics of machines, room acoustics, building acoustics, noise protection and similar problems. Works which are presented during the School are theoretical, experimental, measuring, technical, applied and normative. The School lectures and other conference materials will be published in the “Materials of the XLII Winter School on Vibroacoustical Hazards Suppressions” (in Polish) edited by dr. Roman Bukowski. This publication will be intended for participants of the School and for many libraries in Poland. Other information about the 42nd WS on VHS you can find on our website http://ogpta.pols.pl/szzzw

I have a great pleasure to inform the "AA" Readers that the 40th Winter School on Wave and Quantum Acoustics, organized by Upper Silesian Division of the Polish Acoustical Society and Institute of Physics - Scientific-Didactics Center at Silesian University of Technology, is planned at the turn of February and March 2011 in beautiful scenery of Silesian Beskidy Mountains. Many times it was organized in Wisła, Skoczów, Szczyrk and Korbielów, and this year it will be organized again in Szczyrk.

Traditionally you are invited to acquaint yourselves with some abstracts of lectures submitted to the 40th Winter School on Vibroacoustical Hazards Suppressions. This national School is traditionally held at the turn of February and March and is organized in different places of Silesian Beskidy Mountains. This year it is again held in Szczyrk.

This year we celebrate the jubilee edition of the School. Because of this anniversary the conference apart from standard organizers, i.e. Upper Silesian Division of the Polish Acoustical Society and Institute of Physics - Science-Didactic Center at the Silesian University of Technology, has also a co-organizer - the Committee on Acoustics of the Polish Academy of Sciences. Moreover there are two splendid honorary patrons - Prof. Zbigniew Engel, president of the Committee on Acoustics of the Polish Academy of Sciences, and Prof. Andrzej Bluszcz, director of the Institute of Physics - Science-Didactic Center at the Silesian University of Technology.
