The audiogram configuration of noise-induced hearing loss is characterized by a notching decrease in hearing sensitivity in the frequency region of:

Question

Quizplus · Accepted Answer

The notching decrease in hearing sensitivity in noise-induced hearing loss typically occurs at around 4000 Hz, making option D the best choice. There may also be some decrease in hearing sensitivity at higher frequencies (8000 Hz), but the hallmark feature of noise-induced hearing loss is the dip or notch at 4000 Hz. There is usually not a significant decrease in hearing sensitivity at lower frequencies (250-500 Hz or 500 Hz).
