Assistive listening devices (ALDs) are tools designed to help individuals with hearing difficulties better understand sounds and speech. These devices amplify sound and reduce background noise, making it easier for users to hear conversations in various environments, such as classrooms, theaters, or public spaces. Common types of ALDs include hearing aids, FM systems, and loop systems. ALDs can be used in conjunction with hearing aids or as standalone devices. They are beneficial for people with mild to severe hearing loss, enhancing their ability to communicate and engage in social activities. By improving sound clarity, ALDs contribute to a better quality of life for those with hearing challenges.
