The transparent earpiece 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. 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 earpiece is commercially available both in a vented as well as an occluded version. A scientific paper contianing a detailled description and acoustic evaluation is available here
The Transparent Earpiece will be made available in two versions, one with and one without microphone pre-amps included onboard. The product can be obtained through our partner InEar GmbH, Dieburg.
