  - Automatyka / Automatics - Year 2013

  This paper presents the concept of an acoustic processor of the mine countermeasure sonar. Developed at the Department of Marine Electronics Systems, Gdansk University of Technology, the acoustic processor is an element of the MG-89, a modernised underwater acoustic station. The focus of the article is on the modules of the processor. They are responsible for sampling analogue signals and implementing the algorithms controlling...

• The Caustic in the Acoustics of Historic Interiors

  Publication

  • A. Kulowski

  - APPLIED ACOUSTICS - Year 2018

  In the paper, caustics are discussed as ordered forms of focus broadening occurring in concave mirrors. Presented are examples of caustics formed in natural conditions and application of the phenomenon in different fields of science and technology. Against this factual background, the possibility to observe caustics in rooms is pointed out. Special emphasis is put on large rooms of historic character, as such interiors frequently...

• Analysis of a caustic formed by a spherical reflector: Impact of a caustic on architectural acoustics

  Publication

  • A. Kulowski

  - APPLIED ACOUSTICS - Year 2020

  Focusing sound in rooms intended for listening to music or speech is an acoustic defect. Design recommendations provide remedial steps to effectively prevent this. However, there is a category of objects of high historical or architectural value in which the sound focus correction is limited or even abandoned. This also applies to indoor or outdoor concert shells, installations for teaching and acoustic presentations, etc. The...

  - Year 2005

  W artykule przedstawiono metody cyfrowego przetwarzania sygnału kompleksowego w procesorze akustycznym systemu radiohydroboi. Omówiono ogólną postać systemu oraz sygnału kompleksowego. Opisano dwie alternatywne metody przetwarzania sygnału: pierwszą w dziedzinie czasu, drugą w dziedzinie częstotliwości. Zaprezentowano schematy blokowe algorytmów obu sposobów przetwarzania. Omówiono problemy praktycznej realizacji poszczególnych...
