What are assistive listening devices primarily designed for?

Assistive listening devices are primarily designed to enhance speech perception. This is crucial for individuals who may have hearing difficulties, as these devices focus specifically on improving the clarity of spoken words, making it easier for users to understand dialogue in various settings. By filtering out background noise and amplifying important sounds, assistive listening devices support users in conversations, lectures, and social interactions, hence their focus on enhancing speech over general sound amplification or other functionalities. This targeted support is vital for effective communication, particularly in environments where background noise might interfere.
