Hearing Thresholds (dB HL) for 500 to 4000 Hz by Age Group

	500 Hz	1000 Hz	2000 Hz*	4000 Hz**
Younger adults, Mean ± SD	8.33 ± 6.18	7.50 ± 5.22	3.06 ± 4.58	7.22 ± 5.75
Older adults, Mean ± SD	9.38 ± 6.56	6.56 ± 7.47	7.50 ± 7.30	16.25 ± 10.08

Notes: Hearing thresholds are for the better ear at each frequency. Hearing thresholds were not available for three young adults, although all participants met the minimum threshold requirements stated in the text.
