AGH UST students of the Special Interest Group of Architectural Acoustics have had another success in the international Student Design Competition, winning silver and bronze medals for audio projects. 

Kamil Piotrowski was awarded a silver medal for the project “Multichannel control room designing with the help of High-Order Ambisonic microphone”, which constitutes a part of his master thesis. The author tries to use the so-called “ambisonic microphone” for purely engineering purposes. This type of microphones is designed mainly for recording and reproducing sound in 3D. Kamil Piotrowski showed another use, which will eventually make it easier for acousticians to design playback rooms such as small “home cinemas” and recording studios. On the basis of the procedure and software developed by the AGH UST student, the location system of acoustic defects for this type of rooms becomes a lot easier. 

Adam Szwajcowski was awarded a bronze medal for the project “Method of Directional Characteristics Compression via 4D Shape Representation”, which consists in developing an abstract mathematical model in which frequency constitutes the fourth spatial dimension. Such an approach to reality enables the representation of acoustic directional characteristics in the form of a single four-dimensional shape. The author had designed an algorithm based on the parametrisation of such a shape, thanks to which it is possible to achieve an infinite resolution in space and frequency at a simultaneously significant reduction in the size of files. 

The Student Design Competition took place in Dublin on 20-23 March 2019 within the framework of the 146th Audio Engineering Society Convention, organised by the largest international organisation of sound engineers – Audio Engineering Society. The President of the organisation in Europe (Chair on Europe and International AES SDA) is Bartłomiej Chojnacki, MSc, an AGH UST doctoral student. 

The Student Interest Group of Architectural Acoustics operates at the Laboratory of Technical Acoustics at the Department of Mechanics and Vibroacoustics of the Faculty of Mechanical Engineering and Robotics. The supervisor and scientific mentor of the group is Adam Pilch, DSc. 

The participation of the students in the competition in Dublin was funded from a grant awarded by the Ministry of Science and Higher Education within the framework of the competition “Najlepsi z Najlepszych 3.0” (English: The Best of the Best 3.0).
