Preoperative PTA reported in dB HL, rounded to nearest whole number. Preoperative aided CNC for the ear-to-be implanted reported in percent correct. Age at cochlear implantation reported in years.

The signal-to-noise ratio (SNR) column indicates the subjects who were (+) versus who were not (−) assessed at 0 dB SNR on the sentence recognition in noise task.

NIHL: noise-induced hearing loss; PTA: pure tone average.
