Audiologists are experts in providing specialized treatment for evaluating and managing hearing loss through hearing technology. The purpose of this study is to review the education status of major foreign countries regarding the training of audiologists, their certification management systems, and the audiology education regulations according to international standards; this study compares these with the domestic (i.e., Republic of Korea) education status, certification management system, and audiology education regulations. The regulations, reports, and official documents related to domestic and overseas regarding audiology systems were reviewed and compared. The domestic audiologist education and qualification system is in fair conformity with foreign countries and international standards, but there are areas that need to be improved. If the domestic audiologist qualification system is improved to comply with advanced foreign national audiologist qualification systems and international standards, it will be possible to cultivate a more professional domestic audiologist workforce.

Despite the significant contribution of hearing assistive devices, medications, and surgery to restoring auditory periphery, a large number of people with hearing loss still struggle with understanding speech. This leads many studies on speech perception to move towards the central auditory functions by looking at associated brain activities using macroscopic recording tools such as electroencephalography (EEG). Up until a few years ago, however, limitation has been given to the brain scientists who attempted to investigate speech perception mechanisms using the EEG. In particular, short duration of speech segments has inevitably been used to elicit auditory evoked potential, even though they were too brief to be considered as speech. Today, however, advance in neural engineering and better understanding of neural mechanism have better facilitated brain scientists to perform studies with running stream of continuous speech and expand the scope of EEG studies to include comprehension of more realistic speech envelope. The purpose of this study is to review literatures on neural tracking to speech envelope to discuss it in Audiology perspective. This review article consists of seven subjects including introduction, neural tracking theories, neural tracking measure, signal processing & analysis, literature review on neural tracking associated with hearing loss, application of neural tracking to audiology, and conclusion. We noted that neural tracking has potential to be used in clinical sets to objectively evaluate speech comprehension for people with hearing loss in the future.

The purpose of this study was to identify the differences in language ability and executive functions of children with cochlear implants (CI) and their peer normal hearing (NH) children, and to find out whether the auditory history (duration of CI use, age at implantation) of CI group plays a role as a moderator in controlling the effect size of the differences of the CI and NH groups. A total of 77 articles were searched, 11 studies which met the inclusive and exclusive criteria were selected from three electronic databases (Academic Search Complete, PsycInfo, PubMed). As a result, significant differences were identified in language ability and the five executive function subtypes (working memory, inhibition, shifting, emotion control, and sustained sequential processing) between two groups. But, the hearing history of CI group (duration of CI use, age at implantation) did not appear as a significant moderator. In conclusion, CI children’s language ability and executive function should be precisely monitored and regularly evaluated. In addition, we discussed the possibility that some executive function abilities (plan/organize, attention, and visuo-spatial organization) will remain in CI group. For the follow-up study, we need to identify various factors that support the CI children.

Purpose: The aim of this study was to compose the test for music perception and analyze the characteristic of cochlear implant users’ music perception. Methods: The test was made up with the pitch, melody, and timbre factors, using three low and high frequencies, six music genres, and four types of musical instruments correspondingly. The tests were conducted to 10 normal-hearing (NH) young adults and 10 young cochlear-implant (CI) users. Results: All the music perception tests showed significant differences between NH and CI group [F(1, 4) = 0.018, p = 0.019]. In the pitch test, CI group showed significantly lower correction rate(51.3%) than NH group (82.7%) did with higher correction rates in low frequencies. In the melody test, CI group showed significantly lower correction rate (29.7%) than NH group (95.8%) did with the highest performance in folk songs (51.7%). In the timbre test, CI group showed significantly reduced performance (22.5%) than NH group (65.8%) did. For both CI and NH groups, the pitched percussion showed the highest scores (45% and 100%) while the woodwind showed the lowest scores (13.3% and 48.3%). Conclusion: Out of three tests, CI group showed better performance in pitch perception than melody and timber perception. CI group showed better performances in low pitch sounds, melodies of familiar genre, and sound of pitched percussion instruments’ timber showing complicated music perception ability. To enhance the music perception ability for CI users by aural rehabilitation, more specified and systematic music perception test material should be developed.

Purpose: For comparison of a semantic knowledge processing of the elderly, particularly the normal individuals and individuals with subjective memory impairment, this study aims to clarify what factors of semantic knowledge task could sensitively discriminate between the two groups by conducting various types of tasks and analyzing the aspects. Methods: High/low frequency category fluency test, concrete/abstract noun word defining test, and semantic association task were performed by 30 normal subjects and 30 subjective memory impaired subjects over 65 years old. Total and each subcategory scores were assessed for the category fluency test and word defining test, and correct response and reaction time were measured for the semantic association task. Results: It was found that there were significant differences between the two groups in the total score of the category fluency task (p < 0.001), low-frequency category score, abstract noun word defining task score (p < 0.05), and reaction time of semantic association task (p < 0.01). Conclusion: The result showed that in case of a target word with lower contact frequency and more abstract concept, the elderly with subjective memory impairment have difficulties in neural-networking activation of semantic knowledge and control of interruption stimulation when approaching a target word, with increased reaction time. This findings demonstrate that a semantic and lexical task has a clinical significance in discriminating a subjective memory impairment group.

The elderly with hearing loss have often experienced spatial hearing deficits when only wearing hearing aids. This case study aimed to investigate whether auditory training for spatial hearing loss could improve the spatial hearing ability of the elderly who wear hearing aids. Two older adults (males, aged 75 years and 78 years) who were wearing bilateral hearing aids participated. They had symmetric sensorineural hearing loss. A total of 16 auditory-training sessions (40 minutes, twice per week) for auditory training for spatial hearing ability provided. For outcome measurements, we assessed speech reception thresholds (SRTs) and spatial release from masking (SRM), using two types of noise, steady-state noise and speech-like noise at pre- and post-auditory training. Both subjects increased SRTs after the auditory training, but the SRM of only one participant improved. Also, there were no masking effects for SRM in terms of noise types. Both subjects reported that their trained hearing skills helped in communication with their families and friends. These results suggested that audiologists can consider auditory training for focusing on the spatial hearing loss for the elderly hearing aids users.

Adults who stutter (AWS) may have difficulty in coordination of speech-related muscles movement. Therefore enhancement of coordiantion of speech-related muscles may result in a decrease in disfluency. The current study is a case report of two AWS with intellectual disabilities who received Nanta treatment, non-verbal music therapy technique focusing on coordination of muscles. Two AWS with intellectual disabilities received Nanta treatment for 15 sessions. The Nanta treatment is made up of two goals; body movement to rhythm and speech-related movement to rhythm. Disfluency frequencies for conversation samples were measured pre-treatment, every second treatment, and post-treatment. In addition, a communication test was conducted pre- and post-treatment. Both participants showed a decrease in disfluency frequencies. Moreover there were individualized differences in the changing pattern. However, the participants did not show a positive change in communication attitude. The Nanta treatment may have been effective in reducing disfluency frequencies for the participants of the current study, especially because the treatment was based on non-verbal techniques. These results emphasize that stuttering treatment should be individualized according to the client s characteristics.
