• The Caustic in the Acoustics of Historic Interiors

  Publikacja

  • A. Kulowski

  - APPLIED ACOUSTICS - Rok 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...

  The aim of this study was to develop a method of visual recording and analyzing the vibrations of guitar strings using high-speed cameras and dedicated video processing algorithms. The recording of a plucked string reveals the way in which the deformations propagate, composing the standing and travelling wave. The paper compares the results for a few selected models of classical and acoustic guitars, and it involves processing...

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

  Publikacja

  • A. Kulowski

  - APPLIED ACOUSTICS - Rok 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...

• Modelling and Measurement of Folk Guitar: Truss Rod and Strings in Numerical Analysis of Tone

  Publikacja

  • P. M. Bielski
  • M. Kujawa
  • I. Lubowiecka

  - Archives of Acoustics - Rok 2019

  The study makes an attempt to model a complete vibrating guitar including its non-linear features, specifically the tension-compression of truss rod and tension of strings. The purpose of such a model is to examine the influence of design parameters on tone. Most experimental studies are flawed by uncertainties introduced by materials and assembly of an instrument. Since numerical modelling of instruments allows for deterministic...

• Comparison of two methods of sound extraction from guitar string video recordings

  Publikacja

  • M. Zaporowska
  • A. Czyżewski

  - Rok 2020

  A comparison of two sound extraction methods from guitar string video recordings is presented in the paper. A brief overview of highframe rate camera technology and possible applications are included. The method using the image analysis from two such cameras is presented. The cameras are placed at the angle of 90 degrees for recording the image in three planes. The results achieved...
