The scope of teleaudiology has been noted with telehealth due to Coronavirus disease (COVID-19) recently. As the notion has been around us for more than 20 years ever since 1999, it is necessary to perceive the knowledge accurately and prepare for the successful implementation of it. Therefore, the literature review including screening and diagnostic audiometry, cochlear implants and hearing aids, and aural rehabilitation, telecommunications technology regarding several fields of teleaudiology, and considerations for practicing were identified. Although overall internet-based audiological services showed benefits in terms of outcome and accessibility, uncertainties of cost-effectiveness, the optimal level of support, and a need for further studies of many aspects for teleaudiology has arisen. In the view of technology, the store-and-forward (asynchronous/hybrid) and a real-time (synchronous) methods were introduced with one applied and nine registered patents recorded from 2004 to 2020 for the invention of teleaudiology in the United States. Also, 10 checklists were suggested for planning teleaudiology practice from prior experience in hosting the teleaudiology program. Conclusively, it is hoped that this review sheds light on recognizing and improving the existing teleaudiology services and helps overcome the challenges faced in the era of pandemic and untact world to come.

This study reviewed the pathophysiology of tinnitus. Tinnitus is a symptom that a subject perceives sound regardless of external stimuli. Tinnitus sufferers have reported varying sound types, loudness, and duration of tinnitus. Also, the pathophysiology of tinnitus is also reported to be varied. We searched a web database and found 2,545 articles related to tinnitus. The selection criteria for articles to be reviewed was the year of publication, research category, participant characteristic, publication type, and area of study. Thirty-three studies on the pathophysiology of tinnitus were finally selected and reviewed. Tinnitus pathophysiology was reviewed in relation to the somatosensory, brain, and limbic systems. Fourteen sub-regions were identified to be associated with tinnitus. The data on each sub-region was also reviewed, including its primary role and the tinnitus trigger mechanism. The results of this study can be used as baseline data for studies attempting to understand the mechanism of tinnitus and develop intervention methods.

Background and Objectives: Natural and synthetic speech signals effectively stimulate cortical auditory evoked potential (CAEP). This study aimed to select the speech materials for CAEP and identify CAEP waveforms according to gender of speaker (GS) and gender of listener (GL). Subjects and Methods: Two experiments including a comparison of natural and synthetic stimuli and CAEP measurement were performed of 21 young announcers and 40 young adults.
