Analysis of the spectra of violas with respect to their different bodies
Smola, Ondřej ; Indrák, Michal (referee) ; Jirásek, Ondřej (advisor)
This work focuses on the spectral analysis of three different violas, the modern one, the renaissance one and viola da gamba. Further the work focuses on the formant areas, resonance modes of its resonance corpus and how the resonance modes influence the tembre of the instruments. The theoretical part deals with the history of viola, acoustic-mechanical features, which influence the wood resonance. The practical part focuses on creating the graphic forms of required data needed for spectral analysis, identifying the resonance modes of the instruments and directional characteristics. The sound spectrums of all instruments are compared across the whole practical part. The practical part contains spectrograms, graphs of LPC analysis, graphs of directional radiation and table with formant frequencies of both instruments.
