Article describes the development of a new acoustical seal and coupling technology for hearing devices. The core element of this technology is the Ambrose Diaphonic Ear Lens (ADEL), a user voice-activated expandable balloon that provides an acoustical seal and coupling of a hearing aid to the listener’s ear. A key component is a diaphonic valve used to inflate the ADEL bubble in the ear. This valve harvests sound energy from the hearing aid speaker to pump air into the bubble, while not compromising the sound quality produced by the device. The ADEL inflatable ear coupling provides the ability to fit virtually any ear canal with a single, non-custom device. With the technology, there is also potential for protecting the ear against loud sounds and creating an open ear sensation even though the ear is sealed. The ADEL is expected to eliminate safety issues related to taking an ear impression, such as perforated eardrums. Additionally, remakes and modifications often required by a custom earpiece would be eliminated.
