Description
  • Prace se zabyva subjektivni psychoakusticke hodnoceni nekolika kodovacich formatu pomoci mnoziny psychometrickych metod. Dalsi klicove poznatky je vhodny vyber kritickych signalu, testovacich metodologii a poslouchacu. Autor se pokusi navrhovat a zprovoznit rada testu, jejichz vystup muze byt interpretovan jak QoS daneho algoritmus. Tri psychometricke metody byly pouzite. Konstantni metoda, parove srovnavani a DBTS. Vysledky jsou statisticke zpracovane. (cs)
  • The paper focuses on the subjective psychoacoustic evaluation of some chosen audio coding technologies by a set of psychometric methods. Key parts for the test implementation are the suitable selection of critical signals, testing methodologies and listeners in order to perform an efective test. Based on theoretical and experimental issues from psychoacoustics, the author tries to design and implement a set of tests, which output can be interpreted as the Quality of Service of a given compression algorithm. Three psychometric methods are applied. The constant method, the pair comparison, and the DBTS method recommended by the ITU-1114-1. Results are processed statistically.
