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.
