BSc Bartłomiej Chojnacki – an Accoustic Engineering student at the Faculty of Mechanical Engineering and Robotics is the only Pole to have made it to the finals of the AES Student Design Competition – an international audio industry event. His acoustic scale modeling project  won second place.

The Student Design Competition is held twice a year (in one of European cities and in New York) as an event accompanying the conventions of the Audio Engineering Society– the largest global association of sound engineers. The competition is addressed to students from all over the world and involves presentation of hardware or software design for any audio application. It is open to both teams and individual contestants.

The award-winning project presented by our student was named Acoustic scale modeling – development of a stand for scattering measurement and involved designing a stand for acoustic scale measurement of scattering coefficient. Acoustic reduction models (created in scale, for example: 1:8) require the knowledge of acoustic parameters of materials in a totally different range of frequencies (in the case of the project in question it was 800-40 000Hz). Mr Chojnacki designed a device consisting of a dedicated sound source and a turntable, which enables conducting scattering coefficient measurements for various acoustic diffusers.

The Student Design Competition, which was held together with the 143rd Audio Engineering Society convention from 18 to 21 October, featured 45 projects qualified for this year’s finals. These were selected from all projects entered for the competition on the basis of technical documentation and project descriptions, which took the form of several pages’ long scientific publications. Then, already during the convention, the organisers announced top seven projects, whose authors were asked to deliver project presentations for the jury consisting of the most renowned specialists in the field: Professor Owen Curtin, working for one of the best professional recording studios in the US – Bridge Sound and Stage, Charlie DaVane – leading engineer at MathWorks, where MATLAB software was developed, Robin Lobel – creator of SpectralLayer software, Steinunn Arnardottir, who is head of software division at Native Instruments -  German company manufacturing music software and hardware and, last but not least, Charlie Slee – head of the British section of the Audio Engineering Society and  engineer at Big Bear Audio, which is a company designing and creating products for the acoustics sector. The jury conducted evaluation based on three criteria, which were: the innovative character and complexity of the projects submitted as well as the technical content of the presentation.

As the runner-up, our student was awarded with USD 2500 worth of books, electronic sub-assemblies and a MATLAB licence in addition to the cash award of USD 2000 founded by API –  company founded by Saul Walker, who was a prominent pioneer of audio projects.

During his visit to the United States, Bartłomiej Chojnacki was accompanied by his faculty advisor – dr. inż. Adam Pilch of the Department of Mechanics and Vibroacoustics. Both the visit to the US and the participation in the competition would not have been possible without funds provided by Najlepsi z Najlepszych 2.0 – a scheme financed by the Ministry of Science and Higher Education.

Bartłomiej Chojnacki is the Chairman of the Board of Architectural Acoustics Student Society associated with AGH-UST Technical Acoustics Laboratory. It is worthy of note that in the last year’s edition of the Student Design Competition, held in Paris, Bartłomiej also finished second best while this year he won the title of the ‘Student Nobel’.
