Relation between psychophysical data and speech perception for hearing-impaired subjects. I.
In heterogeneous group of ten hearing-impaired adolescents, relations are studied between several psychophysical test results and speech reception thresholds in quiet and noise. To examine the results, data-reduction techniques were used to extract the most relevant parameters. High correlations were found between the intelligibility of speech in noise on the one side, and vowel-perception parameters resulting from INDSCAL analysis (frequency resolution parameters, critical bandwidth and critical ratio) and audiogram parameters on the other.
