YOU are doing it better!

from The ASHA Leader, February 15, 2011

American adults hear better than their grandparents did at the ame age, according to a study in the December 2010 Ear and Hearing.

Researchers compared hearing data from two national surveys (1959-1962 and 1999-2004) and discovered that men and women todya across the age spectrum have better hearign then their counterparts decades earlier, primarily in the higher frequencies (2000-6000Hz), although hearing in the middle frequency of 1000Hz was roughly the same.

Although the cause for improvement is not clear, researchers noted a viariety of possible factors, including fewer perople who smoke, better health care for people with diabetes and cardiovascular disease, and better care for childhood otitis media.

In addition, vaccines developed in the intervening years protect children from rubella and meningitis. Researchers also noted a decline in noisy manufacturing jobs and an increase in workplace hearing consrvation programs.
