The doctor was testing Ann's ability to distinguish between two similar pitches, which is known as the difference threshold or just noticeable difference (JND). Therefore, the correct choice is D. Auditory convergence refers to the process by which multiple auditory signals combine to create a single perception. Refractory threshold is not related to hearing, and absolute threshold refers to the minimum intensity of a stimulus that can be detected by a sense organ.
