摘要:
QuickSIN test presents a comparative method for assessing hearing impairment. Hearing comparison is based upon keyword perception in test sentences which are masked with babble-type of noise. One's degree of hearing impairment is estimated based on the number of correctly perceived keywords, compared to the person with perfect hearing. The essential parameter during the creation of QuickSIN stimulus sentences is SNR50% (207, 208 and 210), which represents the ratio between speech and noise levels at which the person with perfect hearing perceives 50% of the keywords. Stimulus sentences (215) are obtained after mixing (214) test sentences (204) and noise (213) in a particularly defined energy ratio (SNR). The noise level used for masking of the test sentences (213) depends on the test sentence position in the list, and also on the SNR50%. In order to achieve good keyword perception balance, noise level needs to be adjusted in time, energy, and spectral domains compared to the test sentences (212). After that, the overall test sentence level is set according to both the position of the stimulus sentence in the list, and the SNR50% value (213).QuickSIN test je komparativna metoda procene oštećenja sluha. Komparacija sluha je bazirana na percepciji ključnih reči u test rečenicama koje su maskirane bukom tipa žamor. Stepen oštećenja sluha neke osobe se procenjuje u zavisnosti od toga koliko je ključnih reči ta osoba uspela pravilno da percipira u poređenju sa osobom koja ima neoštećen sluh. Osnovni parametar u kreiranju stimulus rečenica, za QuickSIN test, je vrednost SNR50% (207, 208 i 210), koja predstavlja onaj odnos govora i ometajuće buke pri kome osoba sa neoštećenim sluhom percipira 50% ključnih reči. Stimulus rečenice za QuickSIN test (215) se dobijaju miksovanjem (214) test rečenica (204) i ometajuće buke (213) u tačno definisanom energetskom odnosu (SNR). Nivo ometajuće buke kojim se maskiraju test rečenice (213) zavisi od redosleda stimulus rečenice u listi i
