Finding the age at which the baseline audiogram was taken and recording the corresponding values of age corrections at 1000 Hz through 6000 Hz Subtract the values found in step (i) (B) from the value found in step (i) (A) The differences calculated in step (ii) represented that portion of the change in hearing that may be due to aging.

in the most recent audiogram is 25, yielding 22 after adjustment. Then the hearing threshold in the baseline audiogram at 4000 Hz (5) is subtracted from the adjusted annual audiogram hearing threshold at 4000 Hz (22). Thus the age-corrected threshold shift would be 17 dB (as opposed to a threshold shift of 20 dB without age correction).

Results: The new age-correction values are presented as 2 options. The preferred option is to replace the current OSHA tables with the values derived from the NHANES median better-ear thresholds for ages 20-75 years.

The OSHA age-correction tables are illustrated in figure 1. For example, consider a man whose right-ear baseline thresholds at age 20 years were 10, 15 and 15 dB hearing level at 2, 3 and 4 kHz, respectively; his baseline PTA234 is therefore 13.3 dB. Assume that several years later, at age 40 years, his right-ear PTA234 is now 25 dB.

Objectives: The US Occupational Safety and Health Administration (OSHA) Noise Standard provides the option for employers to apply age corrections to employee audiograms to consider the contribution of ageing when determining whether a standard threshold shift has occurred.

Go to Table A-1 and find the age correction values (in dB) for 4000 Hz at age 27 and age 32. The difference represents the amount of hearing loss that may be attributed to aging in the time period between the baseline audiogram and the most recent audiogram. In this example, the difference at 4000 Hz is 3 dB.
