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.

The analysis of psychoacoustic perception of chords composed from different full and variously colored signals
Vejmělka, Daniel ; Musil, Jaroslav (referee) ; Jirásek, Ondřej (advisor)
This thesis is dealing with the impact of frequency spectrum of musical sounds on psycho-acoustical perception of the listener. It studies how differently filled harmonic spectrums can influence listener’s ability to determine individual notes in a chord and what influence, on recognizability of a chord, inharmonic elements have. It explores different methods of psycho-acoustic measurements and further data processing. The experiment is based on a method of paired comparisons and was realized in a form of listening test with more than 100 participants. The test is focused on typical representatives of different groups of musical instruments. It studies the impact of different colors of sound used in different types of chords. It further deals with statistical processing of the recovered data.
