The Sound Check study, conducted by researchers at NORC at the University of Chicago and funded by the Centers for Disease Control and Prevention, found that nearly 38 million Americans—more than 1 in 9—suffer from some form of bilateral hearing loss. The rate increases to just under 1 in 7 for people ages 35 and older and 1 out of every 1.4 people ages 75 and older.
