Final answer:
A person with mild hearing loss in a quiet environment may have difficulty understanding speech, particularly when it comes to higher frequencies and female voices.
Step-by-step explanation:
A person with a mild degree of hearing loss in a quiet environment may have difficulty understanding speech. Higher frequencies are not as well perceived, so speech may sound indistinct. This can be particularly challenging when trying to understand female voices, which are usually characterized by higher frequencies. Thus, a person with a mild degree of hearing loss may have difficulty understanding normal conversation, especially with women.
