Bunch¹ was the first investigator to demonstrate quantitatively the progressive diminution of hearing acuity for pure tones, particularly of the high frequencies, as a function of age. Later studies^2-3 confirmed his findings. As a result of this research, the American Standards Association⁴ established curves of average hearing level for men and for women to age 65 inclusive. Later curves of the average hearing level to be expected with age were published from the Wisconsin Hearing Survey data.^5-6 None of the large-scale studies included norms for tonal acuity above age 65. However, Sataloff and Menduke⁷ reported data for the age range of 64 to 91 years. They found very little additional hearing decrement for pure tones after age 65, and interpreted their finding to be consonant with previous research. There was, however, considerable variability in tonal acuity in advanced age.

In England, Hinchcliffe^8-9 has recently . . . [Full Text PDF of this Article]
