Each test group contained 10 conditions corresponding to 10 randomly selected lists of Mandarin version of Hearing in Noise (MHINT) materials. The participants enrolled for testing in SSN ranged from 21 to 36 years old (average = 24.9); the participants enrolled for testing in SAM SSN ranged from 21 to 26 years old (average = 22.6); and the participants enrolled for testing in SAM white noise ranged from 20 to 27 years old (average = 23.8)
