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, lectures, or other audio sources. Common types of ALDs include hearing aids, FM systems, and induction loop systems. ALDs can be used in various settings, such as classrooms, theaters, and places of worship. They are particularly beneficial for people who struggle in noisy environments or have difficulty hearing from a distance. By enhancing sound clarity, ALDs improve communication and overall quality of life for those with hearing impairments.
