A Survey of Recent Advances in Hearing Aid Technologies and Trends

Abstract

Hearing aids are small electronic devices worn in or behind the ear to amplify sound for individuals with hearing loss. They work by capturing sound through a microphone, processing it electronically, and then delivering it through a speaker into the ear canal. Modern hearing aids come with various features like noise reduction, directional microphones, and wireless connectivity, making them more effective and convenient for users. This survey paper provides an overview of recent advances in hearing aid technologies, exploring the evolving landscape of assistive devices designed to improve the auditory experience for individuals with hearing impairments. The paper reviews key aspects of hearing aids, including signal processing techniques, device designs, connectivity options, and user-centric features. The survey encompasses highlighting innovative solutions aimed at addressing the diverse needs of hearing-impaired individuals.
