Sažetak
The sensitivity of human hearing is one of the important aspects determining daily living and acoustic comfort. In this paper, the ability of people to discriminate between frequency spectra obtained by filtering out different frequency bands from the spectrum of broadband noise stimuli was tested. Subjective laboratory listening tests were designed and optimized, using the three-alternative forced choice method. The width of the frequency gaps was varied in between 1, 2, 4, 8, 12 and 16 semitones, and reductions 0.3, 0.5, 1, 2, 3, 5, 10 and 20dB were applied. The gaps were created symmetrically (on a logarithmic scale) around two central frequencies: 125Hz and 2000Hz. Altogether 39 subjects were tested.
