Analysis of pitch perception depending on the spectrum
Slávik, Martin ; Indrák, Michal (referee) ; Jirásek, Ondřej (advisor)
This thesis is dealing with the research of the influence of individual harmonic components on the perception of sound height. As a part of the work has been made an internet questionnaire on a web address www.analyzavyšek.9e.cz, where individual respondents completed listening test compound of 46 samples. This experiment is based on semantic differential method. Individual samples are compound of sine wave – tone and examined sample, which respondents evaluates on three bipolar scales. The samples were either modelled by additive synthesis or modified sampled sounds of instruments. Individual samples were divided to four major groups and other minor groups for clarity. The purpose was to find which parts, combinations and harmonic components of sound and tone can affect perception of tone height.

Spectrum analysis of nylon strings
Leznar, Adam ; Hofman, Pavel (referee) ; Jirásek, Ondřej (advisor)
This thesis discusses instruments that use nylon strings in the context of sound quality. The thesis briefly discusses the history of the instruments, where they can be encountered and where they fit within musical instruments. In addition, basic acoustical, physical and mathematical principles relevant to understanding the subject are described. The measurement process and results are then described, comparing samples according to their excitation and how their spectra change at different positions.
