Final answer:
A person with low-frequency hearing loss below 1000Hz will struggle to understand speech, as they can only hear the lowest frequencies and higher frequencies are not well perceived. This can make speech sound indistinct, especially female voices.
Step-by-step explanation:
A person with a low-frequency hearing loss configuration, below 1000Hz, will have difficulty understanding speech. This is because the person will only be able to hear the lowest frequencies and will require speech to be much louder than normal to be understood. Additionally, higher frequencies, which are important for distinguishing speech sounds, are not perceived as well. This can lead to speech sounding indistinct and may particularly affect the ability to understand female voices, which are typically characterized by higher frequencies.
