  • Smartphone-based hearing aid
    Patent number: 10993046
    Abstract: The present invention relates to a smartphone-based hearing aid which does not employ a separate power supply or digital signal processing device and instead has an analogue interface unit, configured with a single integrated circuit chip, connected between a plurality of microphones and a smartphone, thereby realizing a compact size, reducing the cost and enhancing the audio performance. Instead of employing a digital signal processing chip which is essentially used in the existing hearing aids or personal sound amplifiers, the smartphone-based hearing aid according to the present invention utilizes components such as a smartphone-embedded application processor (AP), RAM, digital-analogue converter, speaker and display and is therefore affordable.
