Hearing Health Foundation (HHF)’s scientists study sensory cells in various species to better understand how they are damaged and how they can be regenerated to restore human hearing.
This quest is the premise of our upcoming Operation Regrow campaign. Your donation will be generously doubled by anonymous donors.
Below are five of the most breathtaking images from our scientists’ labs showcasing the beauty of the hearing and balance functions.

New in Hearing and Balance Research
The causes behind residual hearing loss following cochlear implantation are complex and varied. Studies such as this one provide clues as to what to focus on in order to improve the acoustic experience of cochlear implant recipients.
