The purpose of the experiments reported was to establish a
scale of hearing thresholds and intelligibility thresholds
for Croatian sounds. The test material for the experiments
consisted of all possible CV-type syllables.
The result of the experiments show that the hearing thresholds
depend on the vocalic syllable nucleus. The paradox
is that the intelligibility thresholds for consonants are
not related to the relative intensity of their noise parts,
but primarily to the hearing threshold of the vowel in the
syllable. Consonants in a syllable with /i/ have a 9 dB
higher intelligibility threshold than consonants in a syllable
with an /a/ vowel.
These results support the well-known thesis that cues for
the identification of consonants reside within vowel
transients and not in the noise parts of the consonant.
