Smartphone-based hearing aids

The present invention improves while still audio performance, reducing the extra possible to reduce the size of the size by nor not use a power device or a digital signal processing apparatus connected between a single integrated circuit analog interface consisting of a chip a plurality of microphones and a smart phone, cost It relates to a smartphone-based hearing aid can. Smartphone based hearing aid according to the invention, instead of disabling the digital signal processing chip which is essentially used as a conventional hearing aid or individual acoustic amplifier of the application processor embedded in a smart phone (AP), random access memory (RAM), a digital- by utilizing components such as analog converter, speakers and display has low-price advantage. In particular, it is possible to process when utilized in the CPU and GPU incorporated in the application processor of the smart phone using only the software of the short time the digital signal processing unit milliseconds (ms) necessary for hearing aid operation.
