The Consumer Ear Disease Risk Assessment (CEDRA) tool is a questionnaire created by a multi-disciplinary and multi-institutional team of researchers and clinicians. CEDRA was designed to let consumers interested in hearing aids assess their risk for conditions and diseases that affect hearing. The questionnaire has been tested with over 300 participants, and was found to be a good predictor of their disease risk. A study with a larger sample is currently underway at several sites across the nation.

More information is available on the Research page.

CEDRA was developed with support of the Knowles Hearing Center, and NIH/NIDCD grant R21/R33 DC013115.
