Abstract
Hearing impairment is a growing global concern that limits communication and affects the quality of life for millions of people. Conventional hearing aids are often expensive and lack customization options, making them inaccessible for many users. This project presents an open-source, Raspberry Pibased hearing assistance device designed using readily available consumer hardware to provide an affordable and customizable solution. The system captures ambient sound through a microphone, processes it using digital signal processing (DSP) algorithms on the Raspberry Pi, and outputs enhanced audio through earphones. Noise reduction, amplification, and frequency filtering techniques are implemented to improve speech clarity in various environments. The user can control and finetune sound parameters through a simple graphical interface or mobile app for personalized hearing comfort. By utilizing opensource software libraries and low-cost hardware components, this project demonstrates a scalable, flexible, and cost-effective alternative to commercial hearing aids. The proposed system aims to bridge the gap between accessibility and advanced hearing technology, making assistive devices more inclusive and affordable for all.
