The Innovation of oscillators in mechanical-electrical keyboard instruments
Prokop, Šimon ; Buzzi, Mario (referee) ; Jirásek, Ondřej (advisor)
The bachelor thesis deals with innovations of oscillators of mechanical-electric keyboard instruments, especially from the perspective of frequency spectrum innovations. On the basis of the original oscillators of the Rhodes Mk 7 instrument, innovative virtual models of these oscillators were created in SolidWorks, which were subsequently analyzed in Ansys. Subsequently, these assemblies were physically fabricated and tested. In the final evaluation, the signal spectra of the upgraded assemblies were compared with the original tone and the analyzed data. The theoretical part of the thesis also discusses basic signal processing methods and describes methods for evaluating sound perception using psychological acoustics.

The construction of a string instrument with sliding frets
Kotouček, Michal ; Buzzi, MgA Mario (referee) ; Jirásek, Ondřej (advisor)
This thesis describes the design and construction of a string instrument with movable frets and the creation of a computer program for calculating fret positions for various tuning systems. The theoretical part of the thesis deals with different types of tuning systems and describes the method of deriving several types of tunings, from common to exotic and experimental ones. The practical part describes the procedure of manufacture of the instrument, the principle of calculating fret positions and testing the tuning accuracy of the instrument.

Comparison of spectrum and directional dharacteristics of double reed instruments
Cočev, Jiří ; Buzzi, Mario (referee) ; Jirásek, Ondřej (advisor)
The Bachelor's thesis deals with analysis of the sound signals of double reed wind musical instruments. Research focuses mainly on properties of the reed and how properties of reed affects the overall sound of the instrument. For the description of the signals were used FFT, LPC, Autocorrelation and Cepstral analysis. In conclusion, the thesis offers possible future direction for the experimental research of double reed wind musical instruments.
