Lost two-tone suppression degrades speech-formant coding in hearing-impaired listeners.

Evidence

Miller et al. ( 1997 ) related a reduction in 2TS in ANFs to changes in the representation of voiced vowel sounds. Weakened compressive nonlinearities contributed to a reduction in “synchrony capture” by stimulus harmonics near vowel-formant peaks. These effects likely contribute to deficits in across-CF spatio-temporal coding of temporal-fine-structure information in speech for HI listeners (e.g., Heinz et al. 2010 ). — Dijk, Pim van, Physiology, Psychoacoustics and…, 3876
