Abstract: Hearing is one of the most basic human senses. Research shows that 97 percent of the total population of elderly people suffer from hearing loss. This project is designed to address problems that the existing hearing aid users face throughout their use of the product which includes prices, high maintenance, sensitivity to noise, limited functional range and low-quality sound produced. This project aims to provide a hearing aid with noise filtration using Noise Reduction (NR) algorithm. NR algorithm which uses Multi-channel Wiener Filter is implemented to reduce noise and improve speech intelligibility. The proponents create a program for the Intel compute stick using NR algorithm to function as the filter and for the Raspberry Pi as the user interface of the device. The signal gathered by the microphone was processed by the Intel compute stick then outputted through the earphone audio output. The system is tested through simulation in terms of filtering the noise.
