“…Several hypotheses have been proposed to account for the age‐related SPiN decline, but a consensus about the underlying mechanisms is still lacking. Several studies have suggested that normal aging of the peripheral auditory system, called presbycusis , is the main contributing factor to SPiN difficulties in aging (e.g., Akeroyd, 2008; Divenyi & Haupt, 1997; Humes & Christopherson, 1991; Humes & Roberts, 1990; Jerger, Jerger, & Pirozzolo, 1991; Souza & Turner, 1994), but evidence suggesting that SPiN decline cannot be explained solely by presbycusis is accumulating (Bilodeau‐Mercure, Lortie, Sato, Guitton, & Tremblay, 2015; Fostick, Ben‐Artzi, & Babkoff, 2013; Jin, Liu, & Sladen, 2014; Tremblay et al, 2019).…”
