If a tree falls in the
forest, how well you hear the "Tim-berrrr!" may depend on heredity or previous
acoustic exposure. If you've often been exposed to loud noise levels or you have
a family history of hearing loss, your sense of hearing may be impaired. Doctors
at the Mayo Clinic estimate that one-third of Americans over age 60 and one-half
over age 75 have some type of hearing impairment.
Hearing difficulties aren't limited to the elderly alone. Of the babies born
in Wichita, a small but significant number must routinely be fitted with hearing
aids.
"Can You Hear Me Now? The Special Sense of Hearing" is January's Live &
Learn lecture at the KU School of Medicine-Wichita.
