  1. The PTA in the most affected ear is used to define any HL, and the PTA in the less affected ear is used to define bilateral HL. Any HL is considered present if bilateral HL is evident at either high or speech frequencies.
  2. Participants exhibiting HL either at high frequencies (3, 4, 6, and 8 kHz) or speech frequencies (0.5, 1, and 2 kHz) are classified into these categories.
  3. HL, hearing loss; CI, confidence interval; PTA, pure tone average; HFHL, high-frequency hearing loss; SFHL, speech-frequency hearing loss.
