We anticipate that the outcome of this work will be a battery of assessments that will guide hearing aid processing for older patients with hearing loss.","overall_status":"Completed","phases":[],"study_type":"INTERVENTIONAL","sponsor":"Northwestern University","enrollment":49,"countries":["United States"],"start_date":"2015-07-01","completion_date":"2017-07-01","last_update_date":"2020-11-17","source_url":"https://clinicaltrials.gov/study/NCT02448706","editorial_summary":"A registered study indexed because it matched monitored longevity research terms.
