Design of Desktop Spirometer
Monsportová, Kateřina ; Buganská, Tamara (referee) ; Rubínová, Dana (advisor)
The theme of this bachelor thesis is a design of tabletop spirometer. The main goal is to design a device with innovative appearance and shaping, which will provide complex and professional pulmonary examination. The thesis is based on an analysis of the current market and was created with a regard to ergonomic and technical aspects. The final product finds its application in specialized consulting rooms and in general practitioner's office.

The analysis of the clarinet spectrum from different manufacturers
Suchánek, Tomáš ; Mojdl, Edgar (referee) ; Jirásek, Ondřej (advisor)
Bachelor’s thesis focuses on spectral analysis of six B clarinets made by manufacturers Buffet Crampon, RZ Woodwind Manufacturing and Yamaha. Instruments were tested by two professional musicians with different timbral preferences and the resulting spectrum is then applied to how psychoacoustic measurements define timbre perception. Furthermore, the impact of different dynamics or reeds is discussed and significant part of analysis also describes directivity patterns of individual higher harmonics or characteristic formant areas.

The Analysis of spectrum and polar pattern of French horn with different mouthpieces and different elastic resonators
Holba, Stanislav ; Ketner, Zbyněk (referee) ; Jirásek, Ondřej (advisor)
This bachelor thesis deals with the French horn and adjusting mouthpieces for this instrument. The work briefly describes the French horn, its structure, production materials, history and development, and the description of the timbre possibilities. Furthermore, the work explains the use of the fast Fourier transform algorithm in the context of analysis. A list of characteristics features of individual tools and mouthpieces used for analysis follows. The work then compares selected tone samples of natural and valve French horns from various manufacturers, their harmonic spectra, and directional characteristics. For specific tones, a list of chosen psychoacoustic quantities is given. The obtained values are linked with the mechanical characteristics of individual instruments and mouthpieces.
