Modelling of Hearing Aid’s Digital Signal Processor

According to the World Health Organization (WHO), hearing loss (HL) is one of the six key contributors to worldwide disease rates. It is becoming a critical issue in society, not just affecting the aging population, but also negatively impacting young people who are spending more of their spare time performing activities that expose them to excessive noise levels. In this research, we intend to design a filter as a signal processing system in a hearing aid (HA). MATLAB is used to model the digital filter structure, while Simulink is used to capture the entire design. This study examines current critical concerns in hearing aid research from the perspectives of a variety of disciplines. The study proposes a filter and signal processor model based on hearing aid experience, but first, it provides an audiogram for numerous examples to determine if the suggested model would suit or not. The work thus provides an effective compensation of missed high-frequency sounds response in patient hearing by the digital signal processor.
