“…For people with hearing loss, the intelligibility of speech in noise is correlated with the average hearing loss at 2 and 4 kHz ( Smoorenburg, 1992 ) or 2, 3, 4, and 6 kHz ( Amos & Humes, 2007 ). For a review, see Moore (2016) . In addition, the audibility of high-frequency components is important for sound quality ( Brennan et al., 2014 ; Moore, Füllgrabe, & Stone, 2011 ; Plyler & Fleck, 2006 ; Ricketts, Dittberner, & Johnson, 2008 ), detection of word-final /s, z/ ( Füllgrabe, Baer, Stone, & Moore, 2010 ), and identification of speech in noise ( Moore, 2016 ; Plyler & Fleck, 2006 ).…”
