Study population: Patients with unilateral sudden sensorineural hearing loss who was treated in the outpatient department of our hospital.

Brief summary: At present, few research on the auditory perception function and possible neural mechanisms of unilateral sudden hearing loss patients with complete or partial recovery of peripheral hearing.This project evaluate the speech perception function in noise of unilateral sudden hearing loss patients with with complete and partial hearing recovery by cognitive behavioral experiments, event-related potentials (ERPs) and functional magnetic resonance imaging (fMRI), and longitudinal follow-up to explore its underlying neural mechanisms.

Detailed description: 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.

Eligibility criteria: Inclusion Criteria:

* 18-65 years old;
* patients with unilateral idiopathic sudden sensorineural hearing loss (at least three adjacent frequencies of hearing loss ≥ 30 dB );
* the first onset;
* Contralateral hearing is normal; 5) Hearing is cured after treatment

Exclusion Criteria:

* Sudden deafness with possible definite etiology, such as Meniere's disease, large vestibular aqueduct syndrome, trauma, retrocochlear tumor, etc.;
* Severe underlying diseases, heart disease, blood disease, pregnancy, breastfeeding, etc.;
* Suffering from other central diseases that may affect speech perception disorders, such as Alzheimer's disease, etc.;
* Those who cannot cooperate with the whole study inspection;
