The study further aims to examine whether cognitive and cortical mechanisms provide compensatory support for speech perception in challenging listening environments.",[54],"Hidden Hearing Loss",[56,57],"Cochlear Synaptopathy","Age-related Hearing Loss","2026-06-09",{"date":60,"type":61},"2026-06-12","ACTUAL",{"date":63,"type":50},"2026-06-15",{"date":65,"type":50},"2027-05-30",{"name":5,"class":6},1]
