Abstract
Hearing aids are sophisticated electronic devices designed to improve hearing in individuals with hearing impairment. This article explores the working principles, structural components, and signal processing mechanisms of modern hearing aids. The study focuses on how sound waves are captured, amplified, processed, and delivered to the auditory system. Special attention is given to digital hearing aids, which utilize advanced algorithms for noise reduction and sound clarity. Understanding the functional mechanisms of hearing aids is essential for improving clinical outcomes and patient satisfaction. This paper follows the IMRAD structure to provide a comprehensive overview of hearing aid technology.
