Which of the following statements regarding hearing aids is correct?

The correct statement is that hearing aids cannot restore hearing to normal levels. Hearing aids are designed to amplify sound and make it easier for individuals with hearing loss to hear, but they do not cure hearing loss or bring an individual's hearing back to a normal range. They assist in improving a person's ability to hear sounds, such as speech, but the level of comprehension and clarity may still be affected by the underlying condition causing the hearing loss.

The other statements are misleading. While some individuals who use hearing aids may be elderly, many younger individuals also benefit from them due to various types of hearing loss. Additionally, not all hearing aids require a prescription; there are over-the-counter options available as well. Finally, hearing aids are not a solution that completely restores hearing, which further underscores the importance of understanding their function and limitations.
