The Impact

Background and Aim: Tinnitus is one of the most difficult challenges in audiology and oto­logy. Previous studies have been shown that tinn­itus may interfere with the function of central auditory system (CAS). Involvement of CAS abilities including speech perception and audi­tory processing has led to serious problems in people with tinnitus. Due to the lack of enough information about the impact of tinnitus on CAS and its function, and given that there is no standardized protocol for assessment and mana­gement of tinnitus, this study aimed to review the studies on the effect of tinnitus on the CAS function. Recent Findings: Sixteen eligible articles were reviewed. Temporal and spectral resolution, fre­quency differentiation and speech perception deficits were reported in patients with tinnitus, especially in background noise. This was repor­ted even in tinnitus patients with normal hearing. Conclusion: Assessment of central auditory pro­cessing and speech perception in noise seems to be useful for proper management of tinnitus in clinical practice.

Group 1

Background: Impairment in speech perception is a common feature of older adults. This study aimed at evaluating the acute and sub-acute (after three months) effects of auditory training on central auditory processing in older people with hearing loss. Methods: A nonrandomized study was conducted enrolling 15 older adults with hearing loss and an average age of 78.6 ± 10.9 years. All participants underwent a baseline otoscopy, tympanogram, audiogram and speech-in-noise test with a signal-noise ratio (SNR) of 10 and 15 dB. Afterwards, auditory training intervention was implemented consisting of 10 training sessions over 5 weeks. Participants were divided into two groups: group 1 (G1) underwent auditory training based on a speech-in-noise test; group 2 (G2) underwent a filtered-speech test. Auditory processing was evaluated at baseline (T0) immediately after the intervention (T1) and 3 months after the intervention (T2). Results: Group 1 were quite efficient regardless of the SNR in the right ear with statistically significant differences from T0 to T1 (p = 0.003 and p = 0.006 for 10 dB and 15 dB, respectively) and T0 to T2 (p = 0.011 and 0.015 for 10 dB and 15 dB, respectively). As for the left ear, the increase of success was statistically significant for the SNR of 10 dB and 15 dB from T0 to T1 (p = 0.001 and p = 0.014, respectively) and from T0 to T2 (p = 0.016 and p = 0.003). In G2, there was a significant variation only from T0 for T1 in the left ear for an SNR of 10 dB (p = 0.001). Conclusion: Speech perception in noise significantly improved after auditory training in old adults.

Significant Difference

Background and Aim: Frequency discrimination is an important skill in central auditory processing which plays a critical role in proper reading, writing, and speech perception. Music training is among the ways that improve this skill. Most of the reviewed literature is based on the impact of learning music on the early stages of childhood. Therefore, if the tests used in the assessment of central auditory system are proved to be effective in music training in adulthood, they could be recommended as an appropriate option for adult central auditory processing disorder rehabilitation. This study aimed to investigate the effects of learning to play stringed instruments in adulthood on frequency discrimination by pitch pattern sequence test.Methods: This cross-sectional and non-interventional study was performed on 46 normal hearing subjects aged 20-45 years, 28 non-musicians and 18 musicians who were trained to play music as an adult. They were compared by PPST. The results were analyzed by 2-way analysis of variance.Results: There was a significant difference between the average scores of the two groups, the non-musicians and the musicians, for both ears (p<0.001). On the other hand, there was no significant difference between the two test results in both groups gender wise (p>0.05).Conclusion: More correct answers of musicians indicated their better frequency discrimination compared to non-musicians, which could be a reason for improvement in the performance of the central auditory system caused by music training even in the verge of adulthood.

Background and Aim: Researchers in the fields of psychoacoustic and electrophysiology are mostly focused on demonstrating the better and different neurophysiological performance of musicians. The present study explores the imp­act of music upon the auditory system, the non-auditory system as well as the improvement of language and cognitive skills following listening to music or receiving music training. Recent Findings: Studies indicate the impact of music upon the auditory processing from the cochlea to secondary auditory cortex and other parts of the brain. Besides, the impact of music on speech perception and other cognitive proce­ssing is demonstrated. Some papers point to the bottom-up and some others to the top-down pro­cessing, which is explained in detail. Conclusion: Listening to music and receiving music training, in the long run, creates plasticity from the cochlea to the auditory cortex. Since the auditory path of musical sounds overlaps functionally with that of speech path, music hel­ps better speech perception, too. Both percep­tual and cognitive functions are involved in this process. Music engages a large area of the brain, so music can be used as a supplement in rehabi­litation programs and helps the improvement of speech and language skills.

AbstractThe pure-tone audiogram, though fundamental to audiology, presents limitations, especially in the case of central auditory involvement. Advances in auditory neuroscience underscore the considerably larger role of the central auditory nervous system (CANS) in hearing and related disorders. Given the availability of behavioral audiological tests and electrophysiological procedures that can provide better insights as to the function of the various components of the auditory system, this perspective piece reviews the limitations of the pure-tone audiogram and notes some of the advantages of other tests and procedures used in tandem with the pure-tone threshold measurement.To review and synthesize the literature regarding the utility and limitations of the pure-tone audiogram in determining dysfunction of peripheral sensory and neural systems, as well as the CANS, and to identify other tests and procedures that can supplement pure-tone thresholds and provide enhanced diagnostic insight, especially regarding problems of the central auditory system.A systematic review and synthesis of the literature.The authors independently searched and reviewed literature (journal articles, book chapters) pertaining to the limitations of the pure-tone audiogram.The pure-tone audiogram provides information as to hearing sensitivity across a selected frequency range. Normal or near-normal pure-tone thresholds sometimes are observed despite cochlear damage. There are a surprising number of patients with acoustic neuromas who have essentially normal pure-tone thresholds. In cases of central deafness, depressed pure-tone thresholds may not accurately reflect the status of the peripheral auditory system. Listening difficulties are seen in the presence of normal pure-tone thresholds. Suprathreshold procedures and a variety of other tests can provide information regarding other and often more central functions of the auditory system.The audiogram is a primary tool for determining type, degree, and configuration of hearing loss; however, it provides the clinician with information regarding only hearing sensitivity, and no information about central auditory processing or the auditory processing of real-world signals (i.e., speech, music). The pure-tone audiogram offers limited insight into functional hearing and should be viewed only as a test of hearing sensitivity. Given the limitations of the pure-tone audiogram, a brief overview is provided of available behavioral tests and electrophysiological procedures that are sensitive to the function and integrity of the central auditory system, which provide better diagnostic and rehabilitative information to the clinician and patient.

The Relationship

This paper reports a hitherto undescribed relationship between vertigo of central origin and dyscalculia. Subjects with vertigo skipped and displaced decades when counting backwards by two. The error is not recognized when presented visually. The subjects also display decrements in ability to do mental arithmetic and in central auditory processing. The results are discussed in light of the relationship between the central vestibular/auditory system and structures involved in higher cognitive function. The relationship between balance disorders and children with learning disabilities is also examined.

Auditory Analysis

Objective To investigate central auditory processing in children with unilateral stroke and to verify whether the hemisphere affected by the lesion influenced auditory competence. Method 23 children (13 male) between 7 and 16 years old were evaluated through speech-in-noise tests (auditory closure); dichotic digit test and staggered spondaic word test (selective attention); pitch pattern and duration pattern sequence tests (temporal processing) and their results were compared with control children. Auditory competence was established according to the performance in auditory analysis ability. Results Was verified similar performance between groups in auditory closure ability and pronounced deficits in selective attention and temporal processing abilities. Most children with stroke showed an impaired auditory ability in a moderate degree. Conclusion Children with stroke showed deficits in auditory processing and the degree of impairment was not related to the hemisphere affected by the lesion.
