Table 1.
Listener demographics for the HL group, including: sex, age (years), etiology of hearing loss, duration of hearing loss (years), duration of hearing aid use (years), pure tone average (PTA: average air conduction threshold in dB HL at 500, 1000, and 2000 Hz), and average slope over the range between 250–4000 Hz (dB/octave). Listeners are sorted by age and are divided into two sub-groups (younger/older).
