The hearpiece is an electro-acoustic earpiece for research and development on assistive hearing devices and hearables. It includes two balanced armature drivers as well as four microphones in each side, which are built into a one-size-fits-all acrylic shell. The hearpiece fits in about 90% of all ears and has a fit comparable to an individual earmould. It features custom transducer positioning at different positions inside a vent, as well as a microphone inside the ear canal, which opens up many possibilities for signal processing. The hearpiece is available both in a vented as well as an occluded configuration, as well as with and without microphone pre-amplifiers included in the ear.
