What is the role of assistive listening devices (ALDs)?

Assistive listening devices (ALDs) play a crucial role in enhancing sound and facilitating better hearing, particularly in challenging listening environments. These devices are designed to improve the clarity and quality of sound in situations where background noise exists or where the distance between the listener and the sound source makes understanding difficult. For example, ALDs can include FM systems, infrared systems, and induction loop systems that help individuals hear more clearly during lectures, meetings, or social gatherings.

By providing a direct signal from the sound source to the listener, ALDs significantly reduce the impact of competing sounds and improve auditory experiences. This supplements the use of hearing aids rather than replacing them, allowing individuals who have hearing difficulties to enjoy their daily activities more effectively.

The other choices either misrepresent the function of ALDs or suggest a misunderstanding of their purpose within the context of hearing assistance.
