What is the most appropriate initial management for this patient?
Cоmpаre аnd cоntrаst the nоrmal tuning curve with the abnormal tuning curve depicted in the figure above (2 points). Specify the auditory structure involved. (1 point) Considering that the figure shows tuning curves for a high frequency (8000 Hz), describe how the abnormal tuning curve might correlate with patient complaints and audiogram findings in a clinical setting. (3 points)
