IoT based Smart and Efficient Hearing Aid using ARM Cortex Microcontroller

Hearing loss is often associated with poor performance and incident dementia that leads to reduced social engagements, loneliness, and depression. Hearing aids are a solution for hearing loss. Traditional Hearing aids are an electroacoustic device that blocks noise and enhances target sound out of a multi-source mixture. In some cases when the source objects are devices such as mobiles, laptops, or television a higher distortion happens when the traditional hearing aid amplifies the multi-source mixture which leads the wearer unable to extract the exact information conveyed. This paper proposes a smart internet of things based hearing aid which is cost-effective, reliable, and secured. The smart hearing aid compounds the properties of system on- chip property of micro-controllers which allows the user to connect the internet of things based device directly to the hearing aid, therefore, limiting the multi-source mixture. The micro-controller is equipped with an advance digital signal processor that helps in the separation of acoustic sounds and functions more enhanced compared to the traditional ear aids commercially produced.
