Abstract

In October 2011 I was nominated by the President of the Audio Engineering Society as Editor-in-Chief of the Journal of the Audio Engineering Society. My responsibility began in November. Due to large workload of new duties, with this issue I will end my work as Editor-in-Chief of Archives of Acoustics. Beginning from the next issue of 2012, the new Editor-in-Chief, professor Andrzej Nowicki, the Director of the Institute of Fundamental Technological Research (IPPT PAN) of Polish Academy of Sciences will take over the editorial duties. His scientific achievements in acoustics will guarantee the quality of the journal's further development towards strong international position. I was fortunate to have followed in the footsteps of such outstanding Editors-in-Chief of Archives of Acoustics as profs. Leszek Filipczy?ski and Tadeusz Powa?owski, and to have served them both as Associate Editor. I will always be grateful for the possibility to learn editorial skills from them, and to continue the valuable work of my predecessors.

Abstract

Professor Aleksander Opilski has passed away on 20 April 2012. Aleksander Opilski was born on 31 August 1931 in Zagórze in the then Śląskie Voivodship. He underwent his 1st level studies in the years 1950–1953 at the Faculty of Mathematics, Physics and Chemistry of the Jagiellonian University in Krakow. His 2nd level academic education was completed at the Adam Mickiewicz University in Poznań from which he graduated in 1958 as a Master of Science in Physics.

Abstract

The reviewed book is an introductory course on engineering acoustics designed for undergraduates with basic knowledge in mathematics. It is not written clearly enough but in my opinion is it a handbook for students of electrical engineering. Some parts of the material require the knowledge of the basics of electricity and magnetism. Particularly, there are chapters about electromechanical and electroacoustical analogies and electroacoustical transducers. It is not clear whether the course is intended for students who plan to specialize in acoustics or for those for whom this will be the only contact with engineering acoustics. In the second case basic information about physiology and psychology of hearing is missing. The book is divided into 15 chapters. The Authors write that each chapter represents material for two hours of lecture. The 15th chapter does not present a material for a lecture. It contains appendices: basic information about complex notation for sinusoidal signals, power and intensity, supplementary bibliography for self-study and exercises. In my opinion the exercises have various levels of difficulty and should be solved under the direction of a teacher. They are a very important part of the entire course.

Abstract

The 16th International Symposium on Sound Engineering and Tonmeistering (ISSET) organized by the Institute of Radioelectronics and Multimedia Technology (Warsaw University of Technology), Department of Sound Engineering (Fryderyk Chopin University of Music) and the Polish Radio, under auspicious of the Polish Section of the Audio Engineering Society was held in Warsaw on October 8-10 in 2015. The main topics of the Symposium covered mostly all domains of audio engineering, i.e. musical acoustics, noise control, signal processing, room acoustics, radio and television, multimedia, sound engineering and tonmeistering, perception and quality assessment, and many others. The extra attention has been paid for the problems of loudness of audio programs in radio and TV broadcasting. Over 60 people from different branches of audio technology participated in this Symposium and shared their knowledge and experiences during the paper sessions, technical tours, workshops and special presentations. The selection of abstracts of the papers presented at the ISSET’2015 are inserted below.

Abstract

On behalf of Upper Silesian Division of the Polish Acoustical Society (main organizer) and Committee of Acoustics of the Polish Academy of Sciences (co-organizer) we are pleased to announce that it is nearing the end of preparations for the conduct traditionally organized Conferences, which will take place as previously in Szczyrk. At the moment, more than 50 people have confirmed participation in Conferences. They will present more than 40 lectures and reports. 45th Winter School on Wave and Quantum Acoustics constitutes a platform for sharing the results and achievements obtained in different branches of physical acoustics (e.g. molecular acoustics, quantum acoustics, acousto-optics, magnetoacoustics, photoacoustics, acoustics of solid state etc.). Moreover, researches in some selected topics related to those mentioned above (e.g. optoelectronics, relaxation processes) will also be presented during the school. Currently, during the Conference Workshop on Acoustoelectronics and Workshop on Molecular Acoustics, Relaxation and Calorimetric Methods will be held – however, there is a possibility of organizing workshops on other subjects in the future. We would like to invite scientific centers and groups to cooperate in organizing workshops on the subjects of their interests. XLIVth Winter School on Environmental Acoustics and Vibroacoustics is the forum for all environmental and vibroacoustics fields. Particularly it concerns traffic noise, vibroacoustics of machines, room acoustics, building acoustics, noise protection and similar problems.
