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.

Návrh konstrukce vybraných typů mysliveckých zařízení
Ketner, Zbyněk
The aim of this thesis is to propose the construction of selected types of hunting equipment and subsequently implement as part of targeted Business Training Forest Enterprise Masaryk Forest Křtiny. For inspiration, the proposals include a literary resources devoted to this topic, consultation with users of these devices in routine practice and personal experience. During implementation are used ideas and improvements, which may facilitate the construction or use of these devices. Within the work it is necessary to make economic calculation and determine the benefits or disadvantages of the implementation of the construction of these facilities as part of targeted actions for student collaboration. It is necessary to compare the selected types of devices with similar devices on the market.
