The CU Hearing Research Laboratory is recruiting participants for a research study on how our ability to hear interacts with our ability to listen (focus our attention) in difficult listening situations, such as distorted or noisy speech. We are interested in whether measures of attention and memory can help us choose hearing aid settings that make speech more clear. You may be eligible if you are age 18 years or older with normal hearing or with hearing loss in both ears. Please contact us if you may be interested in participating in this study.
