Participant information.

	Hearing threshold range [dB HL]	Pure-tone average (PTA) [dB HL]	Age [years]	No. of females
No hearing loss (HL; n = 8)	0–25	22.3 (7.1)	68.8 (4.6)	4
Mild HL (n = 11)	25–50	42.1 (8.4)	72.5 (5.5)	7
Moderate HL (n = 10)	50–80	63.7 (5.2)	74.6 (6.4)	5
Total (n = 29)		44.1 (17.9)	72.2 (5.8)	16

Participants grouped according to their HL (no/mild/moderate HL; first column), defined based on three ranges of hearing thresholds (second column). Values in parentheses indicate one standard deviation. Average hearing threshold levels for the three groups across 0.5, 1, 2, 4, and 8 KHz are shown in the third column. Columns four and five list participants’ mean age and number of females in the three groups, respectively. The bottom row shows average data across the entire sample of participants.
