In clinical practice, many unilateral sudden hearing loss patients with complete and partial recovery of peripheral hearing still complain of hearing discomfort, especially difficulty in speech recognition in noisy environments. At present, there is still a lack of research on the auditory perception function and possible neural mechanisms of unilateral sudden hearing loss patients with complete or partial recovery of peripheral hearing. From the perspective of cognitive psychology, this project uses cognitive behavioral experiments, event-related potentials (ERPs) and functional magnetic resonance imaging (fMRI) to evaluate the reverberation environment of unilateral sudden hearing loss patients with complete and partial hearing recovery, and longitudinal follow-up to explore its underlying neural mechanisms. The investigators hope to understand the possible difficulties of binaural processing and auditory perception in patients with unilateral sudden deafness, and to explore the changes of central and cortical functions. This study not only has important guiding significance for the treatment and rehabilitation of patients with unilateral sudden deafness, but also expands the research group on auditory perception function and the psychological and neural mechanisms involved in binaural processing, which has important theoretical significance.
