The purpose of this letter is to refute the comments written by Smits, Goverts, and Versfeld (2018).
Refutations to each issue including the fixed mathematical relationship between dynamic range (DR) and a fitting constant (Q value), deviating results for small DRs, and determination of Speech Intelligibility Index (SII) model parameters are described.
Although Smits et al. (2018) correctly identified several issues, those comments do not diminish the results of the original article (Jin, Kates, & Arehart, 2017) in providing new insights for the SII.
Jin et al. (2017) clearly provided the impact of languages and DR on the SII, which was the main result of the study.
