Subjective evaluation of background noise in audio systems
 Falešník, Vlastimil ; Mach, Václav (referee) ; Rášo, Ondřej (advisor)
In this bachelor thesis, the effect of additive background noise on audio recordings was researched. This kind of noise often occurs when these recordings are being restored. The most frequent effort is to suppress these unwanted noises. While suppressing the noises, the most problematic part is that it always depends on subjective evaluation of the listener. Practical impacts of these noises were researched throughout two listening tests. Afterwards, it was necessary to choose proper (ordinal) evaluating scale. The listening tests established the subjective assessment of jammed additive noise degree. Finally, the effect of selected parameters on subjective perceived quality was determined.
