General Interest

We have several research ongoing research projects at any time. Please review the list below and let us know if you are interested in any of the ongoing studies. Our projects typically require you to fill out questionnaires about your hearing or general health. They may also involve tests of your hearing. These tests are done using earphones that are similar to the ear buds used to listen to music or speak on the telephone. Our research projects are held in Evanston on the campus of Northwestern University. Although we often have projects with multiple centers around the country. Parking in Evanston is provided and each session lasts 2 to 3 hours at the longest.
If you or your child are interested in participating in a study please contact us at: or call (847) 467-0123.
