Age-Related Differences in Consonant Processing: Regression Analysis of Performance Intensity Slope

This study examines the relationship between performance intensity slope for various consonants and age-related differences in the signal-to-noise ratio (SNR) threshold difference. The analysis includes data from 19 consonants in both leading and coda positions, comparing older subjects with normal hearing (ONH) to younger subjects with normal hearing (YNH). Averaged values highlight significant changes in consonant processing as a function of age, emphasizing the impact on auditory perception in different age groups.

  1. Figure 8. Regression functions: regression function showing relationship between performance/intensity slope for different consonants and age-related dB signal-to-noise (SNR) ratio threshold difference for each of 19 consonants that occurred in both leading and coda syllable positions. Values have been averaged over leading and coda consonants. ONH = older subjects with normal hearing, YNH = younger subjects with normal hearing. Woods DL, Doss Z, Herron TJ, Yund EW.
