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.

• Study Time Perspective: PROSPECTIVE

Study Groups

Patients with unilateral sudden deafness with complete recovery of peripheral hearing

The patients who recovered from sudden deafness underwent speech recognition rate tests under different masking conditions and different signal-to-noise ratio conditions within 2 weeks after complete recovery of peripheral hearing and were followed up 3 times at 1, 6, and 12 months after recovery. The test content is the same as the first time.

speech in noise test

Intervention Type: DIAGNOSTIC_TEST

The noise masker was a stream of steady-state speech-spectrum noise, whose spectrum was representative of the average spectrum of target sentences. The speech masker was a 47-s loop of digitally combined continuous recordings for Chinese nonsense sentences. Patients from the idiopathic sudden sensorineural hearing loss (ISSNHL) group and control group were tested bilateral (left, right) speech-in-noise (SIN) perception of various signal-to-noise ratios (SNRs) under speech and noise masking conditions. Each participant has to complete four consequent levels of SNRs (-12, -8, -4, 0 decibel (dB) for most of control group, -8, -4, 0, 4 dB for ISSNHL group). In addition, the benefits of spatial separation cues under these two types of masking were analyzed.

Healthy control group

Age-, gender-, and educational-matched healthy controls were enrolled as healthy control group to test speech recognition rates under different masking conditions and different signal-to-noise ratio conditions.
