The hearing loss of deaf participants was confirmed by testing hearing thresholds with audiometry (see Methods and Materials) in the Institute of Speech and Hearing Science at East China Normal University. The averaged hearing thresholds in decibels of each participant are reported in the table. Profoundly deaf group: , 9 females, mean age = 20.84 ± 1.68 years; residual hearing group: , 11 females, mean age = 20.73 ± 2.05 years. SL: sign language. Note: ototoxic drugs mean the misuse of antibiotics.
