Personal and audiometric characteristics of participants. Classification criteria refer to Clark (1981). Uses and abuses of hearing loss classification. Asha, 23(7), 493–500. For each ear we tested frequencies at 125, 250, 500, 750, 1000, 1500, 2000, 3000, 4000, 6000, and 8000 Hz, through a pure tone audiometry.
