Purpose The objective was to assess auditory sequential organization (ASO) ability in children with and without hearing loss. Method Forty children 9 to 12 years old participated in the study: 12 with sensory hearing loss (HL), 12 with central auditory processing disorder (CAPD), and 16 with normal hearing. They performed an ASO task in which they were asked to recall 2, 3, and 5 verbal and nonverbal stimuli with an interstimulus interval (ISI) of 425 ms as well as sequences of 2 elements with an ISI of 20 or 1,000 ms. Results No significant difference was found between the group of children with HL and the 2 other groups on nonverbal stimuli in all testing conditions. Regardless of ISI duration or number of elements in the sequence, children with HL had significantly fewer correct responses than children with normal hearing and children with CAPD for the verbal stimuli /ba/–/da/. Children with HL had significantly better performance than children with CAPD for the verbal a/–/da/ when the number of elements in the sequence varied. Conclusions Children with sensory HL showed impaired ASO ability when recalling verbal /ba/–/da/. Results suggest that hearing loss can induce a specific signature when processing these verbal stimuli.

The present investigation examined the ability of children with and without a hearing loss to correctly reproduce sequences of acoustic stimuli that varied in number, temporal spacing, and type. Forty-eight children took part in the investigation. They were divided into four groups: two groups of 6- and 7-year-old children, 12 with normal hearing and 12 with a sensorineural hearing loss; and two groups of 9- and 10-year-old children, 12 with normal hearing and 12 with a sensorineural hearing loss. All of the children completed auditory temporal sequencing tasks with verbal (/ba/ and /da/) and nonverbal (a 1-kHz pure tone and a wide band noise) acoustic stimuli. For the 6- and 7-year-old children, the results revealed a significant difference between the children with a hearing loss and their peers with normal hearing for immediate recall of verbal sequences. There were no significant differences in performance between the children with a hearing loss and their peers with normal hearing on the nonverbal sequencing tasks or on the nonverbal and verbal memory span tasks. For the 9- and 10-year-old children, the results did not show any significant differences in performance between the two groups of children for the reproduction of sequences containing more than two verbal or nonverbal elements nor for the auditory memory span task when the sequences consisted of verbal stimuli. For the recall of two verbal stimuli with a variable interstimulus interval (ISI) duration, the results showed that the children with a hearing loss experienced more difficulty than the children with normal hearing. Overall, the results indicated that on the auditory sequential organization tasks, the poorer performance of the children with a hearing loss is likely attributable to auditory perceptual processing deficits rather than to poorer short-term memory capabilities. Also, an analysis of the data revealed that the older children obtained significantly better results than the younger children on auditory sequential organization tasks.

Background: Previous studies in a large population of typically developing (TD) children and a smallclinical group showed high correlations between the dichotic and diotic conditions of the Dichotic Digitsdifference Test (DDdT), as well as between DDdT performance and measures of memory and attention.Purpose: The purpose of the study was to investigate the performance on the DDdT in a large clinical sample.Research Design: Correlational analysis between the DDdT diotic condition and the dichotic free recall (FR)right-ear, left-ear, and total (ear-averaged) conditions, as well as between DDdT and memory performance.Study Sample: One hundred one children (6 years, 3 months to 15 years, 0 months, mean 9 years, 6 months)were referred for assessment to the Australian Hearing Central Auditory Processing Disorder (CAPD) service.Results were compared with data from 112 TD children collected from previously published studies.Data Collection and Analysis: Z-scores were used to account for the effect of age on performance.Mean differences between clinical and TD children were investigated using analysis of variance(ANOVA). Pearson product-moment correlations determined the strength of relationships between DDdTconditions and the number memory forward (NMF) and reversed (NMR) subtests of the Test of AuditoryProcessing Skills—Third Edition.Results: Performance by the clinical group on the DDdT dichotic FR (RE, LE, and total) conditions wassignificantly correlated with the diotic condition (r = 0.7; 0.7, 0.8; p < 0.001). Significant correlations werefound between the DDdT diotic and dichotic FR conditions and the NMF (r = 0.5–0.6, p < 0.001) andNMR (r = 0.2–0.5, p < 0.025–0.001). ANOVA revealed no significant difference between the TD andclinical groups (p = 1.0000) in respect to the advantage they got from dichotic listening (calculated asdichotic FR total minus diotic score). Multiple regression revealed that diotic performance and short-termmemory accounted for 68% of the variation in dichotic performance. Random measurement erroraccounted for a further 16%.Conclusions: Factors other than dichotic performance strongly impact a child’s ability to perform a dichoticdigit listening task. This result has widespread implications in respect to the interpretation of CAPDtest results.

Abstract Introduction The auditory structures of the brainstem are involved in binaural interaction, which contributes to sound location and auditory figure-background perception. Objective To investigate the performance of young adults in the masking level difference (MLD) test, brainstem auditory-evoked potentials (BAEPs) with click stimulus, and frequency-following response (FFR), as well as to verify the correlation between the findings, considering the topographic origin of the components of these procedures. Methods A total of 20 female subjects between 18 and 30 years of age, with normal hearing and no complaints concerning central auditory processing underwent a basic audiological evaluation, as well as the MLD test, BAEP and FFR. Results The mean result on the MLD test was of 10.70 dB. There was a statistically significant difference in the absolute latencies of waves I, III and V in the BAEPs of the ears. A change in the FFR characterized by the absence of the C, E and F waves was noticed. There was a statistically significant difference in the positive correlation of wave V in the BAEPs with the MLD. There was a statistically significant difference in the positive correlation of the mean MLD and the V, A and F components of the FFR. Conclusion The mean MLD was adequate. In the BAEPs, we observed that the click stimulus transmission occurred faster in the right ear. The FFR showed absence of some components. The mean MLD correlated positively with the BAEPs and FFR.

AbstractEstrogen has been identified as playing a key role in many organ systems. Recently, estrogen has been found to be produced in the human brain and is believed contribute to central auditory processing. After menopause, a low estrogen state, many women report hearing loss but demonstrate no deficits in peripheral hearing sensitivity, which support the notion that estrogen plays an effect on central auditory processing. Although animal research on estrogen and hearing loss is extensive, there is little in the literature on the human model.The aim of this study was to evaluate relationships between hormonal changes and hearing as it relates to higher auditory function in pre- and postmenopausal (Post-M) females.A prospective, group comparison study.Twenty eight women between the ages of 18 and 70 at the University of Kentucky were recruited.Participants were separated into premenopausal and peri-/Post-M groups. Participants had normal peripheral hearing sensitivity and underwent a behavioral auditory processing battery and electrophysiological evaluation. An analysis of variance was performed to address the aims of the study.Results from the study demonstrated statistically significant difference between groups, where Post-M females had difficulties in spatial hearing abilities as reflected on the Listening in Spatialized Noise Test–Sentences test. In addition, measures on the auditory brainstem response and the middle latency response reflected statistically significant differences between groups with Post-M females having longer latencies.Results from the present study demonstrated significant differences between groups, particularly listening in noise. Females who present with auditory complaints in spite of normal hearing thresholds should have a more extensive audiological evaluation to further evaluate possible central deficits.

This is a report of a female patient in her midthirties who sustained a hemorrhage secondary to an arteriovenous malformation in the region of the pons. The patient's initial symptoms included hearing loss and tinnitus, which were followed by the more characteristic symptoms of headache and loss of consciousness. Results of audiological testing at three months postaccident documented the presence of a hearing loss and a central auditory processing disorder, and the patient was provided an auditory rehabilitation program. Follow-up testing over the course of an additional year documented improvement in both pure-tone threshold and central test results; however, at 15 months postaccident, some auditory deficits remained, especially in the ear ipsilateral to the primary site of lesion. The anatomical correlates of these deficits are discussed, as are the potential contributions of both the auditory rehabilitation program and spontaneous recovery mechanisms to the documented improvements in auditory function.

Rule Out

A central "auditory" processing disorder (CAPD) is an auditory perceptual dysfunction that cannot be explained on the basis of peripheral hearing loss. As a concept, CAPD has not been completely validated, and many issues continue to be controversial. A primary issue of concern is whether currently used tests to evaluate CAPD are sensitive to factors that are not of an auditory perceptual nature. In this paper, we consider the case for modality specificity as a criterion for improving the specificity of diagnosing CAPD. Demonstrating the modality-specific nature of sensory processing deficits is one way to rule out nonperceptual factors as explanations for observed dysfunction.

Two Factors

Central auditory processing disorders among school-age children have been challenging to identify and treat. Many issues remain that need to be resolved. Here, we compare and contrast findings on 331 school-age children who were given two of the more common central auditory processing disorder tests (Staggered Spondaic Word [SSW] Test and the SCAN Screening Test for Auditory Processing Disorders). These results replicate and reinforce many of the psychometric findings reported earlier. The use of factor analysis with these test results was explored. Significantly, two factors emerged, including an auditory binaural separation from competition factor and a monaural low redundancy degradation factor. These findings help us define the nature of processes probed by the SCAN screening test and the SSW test. Furthermore, these findings clarify the use of SSW and SCAN because they showed both SSW Left Competing and Right Competing loading within the same factor, whereas the three subtests on SCAN sorted into two rather than three factors.

Background: In this study, optic coherence tomography (OCT) examination was performed to check whether there was any interaction between ophthalmic axonal structures in unilateral tinnitus patients, and the relationship between optic nerve thickness and cochlear nerve thickness was evaluated. Objective: The aim of the study was to evaluate the relatioship between hearing loss, tinnitus, and nerve thicknesses. Study Design: Prospective study. Setting: Tertiary referral university hospital. Patients: The study included 88 patients with unilateral tinnitus, for which no organic cause could be found in physical examination, psychiatric evaluation, or with imaging methods. Study groups were formed of the tinnitus side and control groups were formed of the healthy side as follows: Group 1 (Non-tinnitus side normal hearing values – n = 30), Group 2 (non-tinnitus side minimal hearing loss – n = 27), Group 3 (non-tinnitus side moderate hearing loss – n = 31), Group 4 (tinnitus side normal hearing values – n = 25), Group 5 (tinnitus side minimal hearing loss – n = 25), and Group 6 (tinnitus side moderate hearing loss – n = 38). Intervention: Retinal nerve fiber layer (RNFL) thickness was evaluated with OCT, and the cochlear nerve cross-sectional area was evaluated with MRI. Main Outcome Measures: RNFL measurements were taken with OCT from the subfoveal area (RNFL-SF) and 1.5 mm temporal to the fovea (RNFL-T µm) and nasal (RNFL-N µm) sectors. On MRI, 3 measurements were taken along the nerve from the cerebellopontine angle as far as the internal auditory canal, and the mean value of these 3 measurements was calculated. Results: When the groups were evaluated in respect of cochlear nerve thickness, a significant difference was seen between Group 1 and both the groups with hearing loss and the tinnitus groups. In the subgroup analysis, a statistically significant difference was determined between Group 1 and Groups 3, 4, 5, and 6 (p = 0.013, p = 0.003, p < 0.001, and p < 0.001, respectively). When the groups were evaluated in respect of the RNFL-SF (µm), RNFL-T (µm), and RNFL-N (µm) values, the differences were determined to be statistically significant (p < 0.001 for all). In the correlation analysis, a negative correlation was determined between hearing loss and cochlear nerve diameter (r: −0.184, p = 0.014), and RNFL-N (r: −0.272, p < 0.001) and between tinnitus and cochlear nerve diameter (r: −0.536, p < 0.001), and RNFL-T (r: −0.222, p < 0.009). Conclusion: The study results clearly showed a relationship between cochlear nerve fiber thickness and hearing loss and the severity of tinnitus in cases with unilateral tinnitus and that there could be neurodegenerative factors in the disease etiology. A similar relationship seen with the RNFL supports the study hypothesis.
