Clinical Trial 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.

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.

Intervention

Diagnostic Test:
• speech in noise 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.
