Ok so scanning the paper, this is just some Adafruit breakout boards (class D amp & electret mic) cobbled together. Is there something that is novel?

- Cogito 7y agoThe novelty is the application, at the price point, tested against a specification. Given that this is an invention/design, seems like a completely respectable piece of work that is not at all redundant (which is the implication I read in your question) even if obvious in retrospect. > The LoCHAid costs only 98 cents (<$1) to mass manufacture and can be personalized for each user through a 3D-printable case. > It is designed to be an over-the-counter (OTC) self-serviceable solution for elderly individuals with ARHL. > Electroacoustic measurements show that the device meets most of the targets set out by the WHO Preferred Product Profile and Consumer Technology Association for Hearing Aids. > Simulated gain measurements show that the LoCHAid is well fitted to a range of ARHL profiles for males and females between the ages of 60-79 years. > Overall, the measurements show that the device has the potential to benefit individuals with ARHL. Thus, our proposed design addresses a long-standing and grand challenge of affordable and accessible hearing technology for every elderly person on this planet.
