Abstract Objectives Our study aimed to verify the evidence of auditory training employed in the audiological treatment of tinnitus in adults and older adults. Methods Scoping review based on a search for articles in journals available in MEDLINE (PubMed), Embase (Elsevier), LILACS (BVS), and Cochrane Library. Titles and abstracts of the retrieved articles were assessed by peers, following the eligibility criteria; they were afterward read in full text, and the references were hand searched in the results found. Studies’ level of evidence was classified into very high (Level A+), high (Level A), moderate (Level B), limited (Level C), low (Level D), or very low (Level D−) based on the Critically Appraised Topics. Results 2160 records were identified in the searching stage and 15 studies were eligible for data extraction. Study design, sample characterization, auditory training tasks, sound stimuli, outcome measures, and results were extracted. Frequency discrimination training was the most frequent strategy, followed by auditory attentional skills training and multisensory training. Almost all studies with daily auditory training sessions reported significant benefits demonstrated in at least one outcome measure. Studies that used auditory discrimination training and attentional auditory skill stimulation to treat tinnitus obtained quality evidence levels ranging from limited to high (C‒A) and studies that applied multisensory training or attentional training combined with counseling and passive listening in tinnitus patients reached a high-quality evidence level (A). Conclusion Recent studies had higher levels of evidence and considered attentional factors and multisensory pathways in auditory training strategies.

Abstract Introduction Peripheral hearing loss, besides causing inadequate auditory input, can lead to distortions in the tonotopic auditory map and reorganization of neural networks. Therefore, the processing of temporal aspects of a sound stimulus and, consequently, the effectiveness of human communication can be negatively impacted. Objective To test the temporal ordering and auditory resolution of people with mild and moderate sensorineural hearing loss and to compare them with the those of people with normal hearing. Methods A total of 19 right-handed individuals aged 16 to 59 years with mild to moderate postlingually acquired symmetric bilateral sensorineural hearing loss participated in the study. They were submitted to frequency and duration pattern tests and a random gap detection test. Results The mean correct response rate in the frequency pattern test was of 66.3%, and, in the duration pattern test, 71.7%. The mean threshold in the random gap detection test was of 14.1 ms. A comparison with the criteria established for normal subjects without peripheral hearing loss revealed that more than half the subjects had abnormal results in the temporal ordering test, while a smaller fraction had reduced temporal resolution. Conclusions The performance of the subjects with acquired sensorineural hearing loss was poorer than that of the participants without peripheral hearing loss. Their results on the temporal ordering test were also poorer than in the temporal resolution test, demonstrating the importance of analyzing both these auditory skills in people with peripheral hearing loss. input networks Therefore consequently impacted 1 righthanded right handed 5 study 663 66 3 66.3% 717 71 7 71.7% 141 14 14. ms 6 66.3 71.7 66. 71.

Abstract Introduction: Traumatic brain injury can impair the central auditory pathways and auditory cortex. Hence, individuals who suffered a traumatic brain injury may be at risk of central auditory processing disorders, which can be identified with behavioral tests that assess central auditory function. Objective: To characterize and compare the performance of children and adolescents with and without a history of traumatic brain injury in behavioral tests that assess central auditory processing. Method: The sample comprised 8- to 18-year-old individuals of both sexes who suffered moderate or severe closed traumatic brain injury 3 to 24 months before their participation in the study and whose hearing thresholds were normal. These individuals were matched for sex and age with other subjects without a history of traumatic brain injury and submitted to behavioral assessment of the central auditory processing with special tests to assess hearing skills (namely, auditory closure, figure-ground, and temporal processing), selected according to their chronological age and response-ability. Results: The study group performed statistically worse than the comparison group in auditory closure, figure-ground in verbal dichotic listening, and temporal ordering. The central auditory processing tests with abnormal results in the comparison group were different from those in the study group. Conclusion: Central auditory processing disorders were identified in all subjects of the study group, especially involving auditory closure and temporal processing skills, in comparison with subjects without a history of traumatic brain injury.

Abstract Introduction Dysphonia is an oral communication disorder. The voice and hearing are interrelated aspects. Hearing is an important sensory input for monitoring the vocal pattern. The relation between hearing abilities and dysphonia represents a contribution both in scientific and in clinical terms, especially in cases in which satisfactory results are not achieved in the therapeutic process. Objective To characterize long-latency auditory evoked potential (P300) with tonal and complex stimuli, and to make a behavioral evaluation of auditory processing in adults with behavioral dysphonia. Method The sample used for the present study consisted of 20 subjects from both genders with ages ranging from 18 and 58, who were diagnosed with behavioral dysphonia. The evaluations occurred in a single 2-hour session, in which the procedures of clinical history, pure tone and speech audiometries, acoustic immittance measures, and behavioral and electrophysiological evaluations of auditory processing were performed. Results The descriptive measures of P3 latency elicited by tonal and complex stimuli showed similar results for the right and left ears, without statistically significant differences. In the qualitative analysis, the results observed were within the normality patterns for the P3 component for both tonal and complex stimuli. As for the behavioral evaluation of auditory processing, abnormal results were observed in 100% of the sample. Abnormalities were found in the auditory skills of ordering and temporal resolution and figure-background obtained from the duration pattern, random gap detection, and dichotic tests (syllables and words), respectively. Conclusion The evaluated patients presented central auditory processing disorder, evidenced by behavioral assessment.

ABSTRACT Purpose: to identify the Scale of Auditory Behaviors perception after an acoustically controlled auditory training program. Methods: 23 individuals of both genders, aged 6 to 15 years, participated in this study. Inclusion criteria: to present auditory thresholds lower than 20 dBHL between 250 and 8000Hz, type A tympanometry and diagnosis of central auditory processing disorder confirmed by behavioral tests with indication of acoustically controlled auditory training which was performed in ten one-hour sessions. Hearing tests in progressively adverse listening conditions were used. In the first and last session of the acoustically controlled auditory training program, the individuals were submitted to the Scale of Auditory Behaviors. The appropriate statistical tests were applied considering a p-value less than 0.05. Results: questions Q1, Q2, Q4, Q7, Q8 and Q11 showed statistically significant results and improvement in behaviors after the acoustically controlled auditory training. On the other hand, questions Q3 and Q10 showed a tendency towards significance and the total score in the post time period increased in relation to the pre-moment, pointing to a statistically significant difference that represents complaint reductions. Conclusion: the subjective perception of the individuals and their family members could be identified by the application of SAB in the pre and post auditory training, revealing an improvement in auditory and attention behaviors.

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.

RESUMO Objetivos: verificar o funcionamento das células ciliadas externas e do sistema olivococlear eferente medial e a integridade das vias auditivas no tronco encefálico até o córtex auditivo, em indivíduos afásicos.

No potencial cognitivo, o valor médio das latências P3, mostrou-se dentro dos padrões da normalidade com maior latência nos indivíduos com afasia para o estímulo toneburst em ambas as orelhas. Observou-se diferença estatisticamente significante da amplitude P3-N2 para o estímulo toneburst, comparando as orelhas em ambos os grupos, e para o estímulo de fala apenas à orelha esquerda em ambos os grupos. Conclusões: indivíduos afásicos não apresentaram diferenças significantes quanto à supressão das emissões otoacústicas. Quanto ao potencial cognitivo, os indivíduos afásicos apresentaram maior valor de latência em relação aos indivíduos sem afasia.

ABSTRACT Purpose: to verify the functioning of the outer hair cells and the medial efferent olivocochlear system, and the integrity of the auditory pathways in the brainstem up to the auditory cortex, in aphasic individuals. Methods: the sample comprised 20 individuals - 10 without aphasia and 10 with it, aged from 21 to 58 years. The procedures used were the research of the otoacoustic emissions by a transient stimulus with and without noise, and the cognitive potential (tone-burst and speech stimuli). The findings were analyzed based on descriptive statistics. Results: the suppression effect was more present in individuals without aphasia when compared with the aphasic ones. In the cognitive potential, the mean latency values of P3 was within normality standards, with a higher latency in the individuals presented with aphasia for the tone-burst stimulus in both ears. A statistically significant difference of the P3-N2 amplitude was observed for the tone-burst stimulus, comparing the ears in both groups, and for speech stimulus only to the left ear in both groups. Conclusions: aphasic individuals did not present significant differences regarding suppression of the otoacoustic emissions. As for the cognitive potential, the aphasic individuals presented higher latency values when compared to those with no aphasia.

RESUMO Objetivo: descrever os achados audiológicos e das emissões otoacústicas em pacientes com câncer de cabeça e pescoço e compará-los com indivíduos sem a doença. Métodos: estudo observacional transversal comparativo realizado em dois grupos: Estudo: indivíduos com histórico de câncer de cabeça e pescoço submetidos à quimioterapia e/ou radioterapia; Controle: indivíduos sem a doença. A amostra foi composta por 23 indivíduos em cada grupo, pareados considerando idade e gênero. Procedimentos: meatoscopia; audiometria tonal liminar e de altas frequências; logoaudiometria e emissões otoacústicas evocadas transientes, comparados entre os grupos. Testes estatísticos: Qui-quadrado de Pearson; exato de Fisher; igualdade de duas proporções; Wilcoxon; Mann-Whitney e t de Student. Resultados: a comparação entre os grupos revelou diferença estatisticamente significante nas frequências de 3, 6, 8, 10 e 12,5kHz na audiometria tonal liminar, com melhores limiares auditivos tonais no grupo controle. Não foram observadas diferenças significantes entre os grupos nas emissões otoacústicas, quanto a resposta geral e banda de frequência. Conclusão: indivíduos com histórico de câncer de cabeça e pescoço apresentam limiares auditivos tonais mais elevados do que seus controles, sobretudo nas frequências altas, evidenciando o efeito deletério da ototoxicidade no sistema auditivo periférico de adultos. As emissões otoacústicas mostraram-se semelhantes nos dois grupos.

ABSTRACT Purpose: to describe the audiological and otoacoustic emission findings in patients who had head and neck cancer and compare them with individuals without the disease. Methods: a comparative, cross-sectional, observational study encompassing two groups: Study: individuals with a history of head and neck cancer, submitted to chemotherapy and/or radiotherapy; Control: individuals without the disease. The sample comprised 23 individuals in each group, matched for age and gender. Procedures in which the groups were compared: meatoscopy; pure-tone threshold and high-frequency audiometry; speech audiometry; transient-evoked otoacoustic emissions. Statistical tests: Pearson’s chi-square; Fisher’s exact; two-proportion Z-test; Wilcoxon; Mann-Whitney; Student’s t-test. Results: the comparison between the groups revealed statistically significant differences at the 3, 6, 8, 10, and 12.5 kHz frequencies in the pure-tone threshold audiometry, with better pure-tone auditory thresholds in the control group. No significant differences were observed between the groups in the otoacoustic emissions regarding the general response and frequency band. Conclusion: individuals with a history of head and neck cancer had higher pure-tone auditory thresholds than their controls, especially at the higher frequencies. This evidences the deleterious effect of ototoxicity on the peripheral auditory system of adults. The otoacoustic emissions were similar in the two groups.

Abstract Introduction The mismatch negativity (MMN) is a negative long-latency auditory potential elicited by any discriminable change in a repetitive aspect of auditory stimulation. This evoked potential can provide cortical information about the sound processing, including in children who use cochlear implants. Objective To identify MMN characteristics regarding latency, amplitude, and wave area in cochlear implanted children and to identify associations among language development, speech perception and family involvement. Methods This is a descriptive, observational, cross-sectional study, which compared two groups: study group-children with cochlear implant, and control group-hearing children. The children were submitted to MMN evaluation with non-verbal tone burst stimulus, differing in frequency in sound field at 70 dBHL, with SmartEP equipment (Intelligent Hearing Systems, Miami, FL, USA). Speech perception and language development questionnaires were also applied, and the family participation in the rehabilitation process was classified. Results The occurrence ofMMNwas 73.3% for the control group and 53.3% for the study group. Values of latency, amplitude and area of MMN of children using cochlear implants were similar tothose ofhearingchildren, anddidnot differbetweengroups. The occurrence of MMN was not correlated to the variables of hearing, language and family categories. Conclusion Children with cochlear implants showed similar MMN responses to those of the children in the control group, withmean latency, amplitude andarea of 208.9ms (±12.8), -2.37 μV (±0.38) and 86.5 μVms (±23.4), respectively. There was no correlation between the presence of MMN and children’s performance in the auditory and language development tests or family involvement during rehabilitation.

ABSTRACT Purpose To evaluate the influence of variables age, educational status and sex in the occurrence of pauses after the standard time in the dichotic sentence identification test. Methods This investigation included 200 right-handed subjects divided into four groups according to age: group I - from 13 to 19 years old, group II - from 20 to 29 years old, group III - from 30 to 39 years old and group IV - from 40 to 49 years old. Each group contained 50 subjects (25 men and 25 women) matched by educational level. The following eligibility criteria was adopted: Brazilian Portuguese mother language, listeners, and fluent readers independent of the educational level. It was applied the dichotic sentence identification test in the steps of binaural integration, directed listening, and it was noted the need for pauses in the test after the standard time. The descriptive and inferential statistics were performed. Results For the binaural integration stages there was a positive association between age and pause occurrence. The educational variable presented a negative association with the occurrence of pauses in all stages of the DSI test. The gender variable showed no association with the occurrence of pause in any of the test steps. Conclusion With increasing age, there is an increase in the incidence of pauses in the binaural integration stages of the test. The more years of study the less chance that the individual will need breaks to perform the test at all stages of presentation. The variable gender did not influence the occurrence of pauses.
