tSeveral researchers have studied primitive cultures to determine the influence of aging on hearing acuity in the absence of occupational noise. These
studies found aging effects on
hearing, but observed no
sex difference in the hearing loss.

tAnimal studies have also found no sex difference.
Hunter KP, 1987
tIt has been proposed that the difference between male and female thresholds as a function of age, is due to environmental factors. The most important of which is noise exposure. Kryter KD, 1983
