This research paper investigates the role of the primary auditory cortex in fine-grained loudness perception. It presents a case study of a 46-year-old male with bilateral lesions in the primary auditory cortex due to ischemic infarcts, resulting in profound deafness and altered sound perception. The study compares his auditory thresholds and loudness discrimination with normal controls, suggesting that the primary auditory cortex is crucial for fine-grained intensity discrimination, while the auditory brainstem can mediate coarse loudness perception.
