What is a hearing aid primarily designed to do?

A hearing aid is fundamentally designed to amplify sound before it reaches the receptor organs, specifically the ears. This amplification allows individuals with hearing loss to better hear sounds that they may struggle to detect on their own. By increasing the volume of incoming sounds, hearing aids help users engage in conversations and enjoy auditory experiences that would otherwise be challenging.

While hearing aids can reduce background noise to some extent, this is typically an additional feature rather than their primary function. Similarly, while they can facilitate easier speech comprehension by making sounds louder and clearer, the core purpose remains focused on amplification. As for providing sound feedback, generally, hearing aids are designed to minimize feedback that can be disruptive, rather than enhance it. Thus, the primary role of a hearing aid is effectively to amplify sound before it enters the auditory system, making option B the most accurate response.
