PATIENTS CAREERS CONTACT ABOUT OUR SCIENCE PIPELINE & PROGRAMS HEARING LOSS INVESTORS & MEDIA Millions are impacted by hearing loss. We're seeking to restore the clarity they've lost. LEARN MORE Reimagining Treatments for Hearing Loss More than 40 million people in the U.S. struggle with acquired sensorineural hearing loss, the most common type of hearing loss. This condition affects more than just hearing; it’s about communication and speech perception. Individuals may have difficulty speaking on the phone, struggle in school or at work and become socially isolated. What may start as a minor inconvenience can get progressively worse and is associated with other serious medical conditions like depression and dementia. Current treatments can help make sounds louder, but we’re leading the creation of the first-ever disease-modifying therapy for sensorineural hearing loss — one that aims to restore hearing function and enhance the ability to clearly understand speech.
