Average pure-tone thresholds for the test ear of EHI listeners across CENTER, MARGIN, ONSET, and OFFSET conditions ( per condition) displayed by broken lines in dB HL (ANSI, 1996). Solid line displays the LTASS in dB HL when calibrated at the SPL level.
Temporal waveforms of the syllable “mean” (/min/) extracted from a test sentence, “What did you mean by that rattlesnake gag?”. Top waveform of “mean” is from the original sentence with no interruption. Portions inside the boxes from second to fifth waveforms display four different subsegmental cues preserved in each condition (CENTER, MARGIN, ONSET, and OFFSET from second to fifth waveforms) for the 50% proportion of duration, while the regions outside the boxes are replaced with SSN.
Root-mean-square amplitude spectra of the concatenated 42 sentences processed in the four conditions (CENTER, MARGIN, ONSET, and OFFSET) as a function of frequency. Note that all sentences used in the current study were low-pass filtered at .
Mean number of words correct in percentage in each of four conditions for YNH and EHI listeners with 50% duration (YNH-50 and EHI-50) and for YNH and EHI listeners with 70% duration (YNH-70 and EHI-70). Error bars indicate standard errors.
Scatter plots of data for word scores by EHI-70 as a function of high-PTA (from 1, 2, and ) in the left panel and as a function of age in the right panel.
Spectra of the concatenated sentences used in VIN and CIN conditions (from KBL07) displayed as unfilled circles and unfilled squares, respectively. The filled triangles show the amplitude spectra of the concatenated sentences across the four subsegmental conditions with 50% duration (Sub-50).
The first row shows the duration (%) in each condition across current and KBL07 studies. The score of words correct (%) with standard errors (SEs) is displayed in the second row for both YNH and EHI listeners.
Examples of the four error types for incorrect words (phonetically matched word, MW; phonetically unmatched word, UW; phonetically matched pseudoword, MP; and phonetically unmatched pseudoword, UP).
Distribution (%) of four types of errors for the incorrect word responses pooled across conditions.
Spearman rank correlations for the sentence ranking between groups. The first column and row show the mean group performance [ of words correct (%) across conditions and errors]. Significant correlations are marked with .
