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.

Psychoacoustic model of human hearing
Lepa, Ondřej ; Smékal, Zdeněk (referee) ; Sysel, Petr (advisor)
This thesis deals with human auditory system and psychoacoustics. Deals with psychoacoustic model of standard MPEG following the norm ISO/IEC 13818-3, Information technology - Generic coding of moving pictures and associated audio information Part 3: Audio. Closer look is given to determination of PAM, to methods of masking and what potential of masking it has. Next the simple computation of psychoacoustic values is~done in Matlab environment.
