 Hi everyone, my name is Amelie and I'd like to show you the project Primage A in this short video. The basis for this work is my final thesis, which I have completed just a few months ago. Hearing loss is a burden on daily life. Fortunately, hearing aids can help. The underlying technology has developed steadily over the past decades, but it is far from perfect. Just think of the cocktail party effect. Latest hearing aid hardware usually has multiple computing cores, as well as a multitude of co-processors and accelerators. Nevertheless, power consumption must be kept to a minimum, so that hand-optimized firmware development becomes inevitable. Consequently, research and development are unnecessarily complicated and knowledge sharing is nearly impossible due to highly specialized hardware. That's why we wanted to create a behind-the-ear wearable platform, which consists of commercial of the shelf components, has approximately the performance and capabilities of a hearing aid and is easy to program. This ensures both easy testing of new algorithms in real and challenging acoustic environments and transferability to hearing aids. We have abstracted the functionality of a hearing aid and adopted it as the basis for the architecture. The shape and components of Prime Edge A have been selected carefully to ensure ease of use, see programmability and similar to hearing aid performance. I designed an electrical circuit and realized it as a four-layer PCB. Then, a fitting enclosure was constructed and 3D printed. Finally, we assembled a handful of actually working prototypes. To protect developers' hearing, we've built in safety mechanisms to limit the output level. My call you first algorithms to be tested by means of the Prime Edge A. In addition, the prototypes were characterized and calibrated, so that testing of algorithms in realistic environment is possible. Thank you for your attention. I hope to see you at the VCCA.
