Traditional analog hearing aids is same as simple radio. They can be calibrated and adjusted for volume, bass and treble. But hearing loss is not just a technical loss of volume. Rather, hearing scantiness can intensify sensitivity and reduce tolerance to certain sounds while diminishing sensitivity to others. For instance, digital technology can tell the difference between speech and background noise, permitting one in while filtering out the other. More or less 10% of the world's population suffers from some type of hearing loss, yet only a small percentage of this statistic use a hearing aid. The stigma connected with wearing a hearing aid, customer disappointment with hearing aid performance, and the cost related with a high-performance solution are all causes of low market penetration. Through the use of digital signal processing, digital hearing aid now gives what the analog hearing aid cannot give. It suggests the possibility of performing signal-to noises strengthen, pliable gain-processing, digital feedback reduction, etc. In this paper, the simulation of simple digital hearing aid was developed using MATLAB programming language. The implementation of this configurable digital hearing aid system includes the noise reduction filter, frequency shaper function, and amplitude compacting function. This digital hearing aid system is design to adapt for mild and moderate hearing loss patient since different gain can be set to map different levels of hearing loss.
