The analysis of psychoacoustic perception of chords composed from different full and variously colored signals

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
