Which statement about conductive hearing loss in loud environments is true?

In conductive hearing loss, the problem lies in the outer or middle ear, which reduces the amount of sound that reaches the inner ear. Because the inner ear and auditory nerve are still functioning, a louder environment can sometimes push more acoustic energy through the attenuated pathway, making sounds more audible than in a quiet setting. There’s no recruitment like you can see with many sensorineural losses, so increasing loudness doesn’t cause a sudden rush of extra loudness and distortion in the same way. That’s why a person with conductive loss might actually hear better in a loud environment than in a quiet one. So, the statement that hearing may be better in loud environments fits with how conductive loss works. It isn’t about being unaffected by loudness, and it’s not about vestibular effects, so those options don’t apply.
