What is one main purpose of assistive listening devices (ALDs)?

Enhancing sound amplification or captioning is a primary purpose of assistive listening devices (ALDs) because these devices are specifically designed to improve the user’s ability to hear in challenging listening environments. Unlike hearing aids that are primarily used for general hearing assistance, ALDs focus on delivering sound more directly to the user's ears, often bypassing environmental noise and distance factors that can hinder comprehension. For example, devices like FM systems and induction loop systems can amplify speech sounds in settings such as classrooms, theatres, or public spaces, facilitating clearer communication.

In addition, many ALDs provide captioning options for users who may benefit from visual text to supplement auditory information, making conversations and media more accessible. This is particularly valuable for individuals with varying degrees of hearing loss, ensuring that they receive auditory information in a manner that suits their needs, thus enhancing overall communication effectiveness.
