Use of masks in the oral communication of hearing device users / Uso de máscara na comunicação oral para usuários de dispositivos auxiliares à audição

ABSTRACT Purpose: to assess the influence of wearing a mask on auditory-visual speech recognition, in a favorable listening situation, in hearing devices users. Methods: a cross-sectional observational study comprising 52 hearing aid users, whose speech recognition was assessed with six video-recorded lists of sentences with and without masks. The mean test results in the various situations were compared using the Friedman test with Bonferroni post hoc, the significance level being set at 5%. Results: speech recognition assessment results differed between the situations with and without masks and between mask types, with a small effect size. The post hoc, with p-values adjusted with the Bonferroni method, showed a difference between transparent masks and others. The transparent one had a higher mean (77.8%) of auditory-visual sentence recognition between the various situations. There were statistically significant differences, as the transparent mask provided a better performance than the others. Conclusion: the auditory-visual recognition of the hearing-impaired people was better with the transparent mask.

RESUMO Objetivo: avaliar a influência do uso de máscara no reconhecimento auditivo-visual de fala, em situação de escuta favorável, em usuários de dispositivos eletrônicos auxiliares à audição (DEAA). Métodos: estudo observacional transversal. Participaram 52 usuários de dispositivos auxiliares à audição que realizaram avaliação do reconhecimento de fala com seis listas de frases apresentadas em vídeo com e sem máscaras. Para comparar as médias dos resultados do teste nas diferentes situações, foi aplicado o Teste de Friedman, com pos-hoc de Bonferroni e nível de significância 5%. Resultados: houve diferença dos resultados da avaliação de reconhecimento de fala entre as diferentes situações, com e sem máscara, assim como entre os tipos de máscara, com tamanho de efeito de pequeno. O post-hoc, com valor de p ajustado pelo método de Bonferroni, mostrou diferença entre a máscara transparente e as demais. A máscara transparente apresentou maior média (77,8%) do reconhecimento auditivo-visual nas sentenças utilizadas entre as situações. Foram observadas diferenças estatisticamente significantes com desempenho superior da máscara transparente em relação aos outros tipos de máscaras. Conclusão: conclui-se que o reconhecimento auditivo-visual para os deficientes auditivos foi melhor com a máscara transparente.

Self-reported hearing difficulties and speech-in-noise test performance - what can we find behind a "normal" audiogram? / Autorrelato de dificuldades auditivas e desempenho em teste de fala com ruído - o que podemos encontrar por trás de um audiograma "normal"?

PURPOSE: To investigate complaints of difficulty understanding speech in the presence of noise in subjects without hearing loss and their performance on a speech-in-noise test. METHODS: Thirty-nine subjects aged 18 to 59 years and 11 months were divided into four groups according to their decade of life. They underwent audiometry, tympanometry, auditory processing tests, the Mini-Mental State Examination, a self-report on auditory perception combined with the Amsterdam Inventory for Auditory Disability and Handicap (Pt-AIADH), and a sentence test in silence and in noise. RESULTS: All groups scored high on the Pt-AIADH domains, with the highest average score obtained for the noise intelligibility domain. There were differences between G18 vs. G40, G18 vs. G50, and G30 vs. G50 for auditory self-perception in noise intelligibility, and differences between the youngest and all other groups on the speech-in-noise test in particular, with a lower signal-to-noise ratio for older adults. We also identified a moderate and significant correlation between intelligibility in noise and the speech-in-noise test. CONCLUSION: Normal hearers of all age groups complained of intelligibility in noise. We found that the higher an individual's auditory difficulty in this domain, the worse their performance on the speech-in-noise test; this is especially true for middle-aged adults.

OBJETIVO: Investigar a queixa de dificuldade de inteligibilidade na presença de ruído, em sujeitos sem perda auditiva e compará-la com o desempenho em um teste de fala no ruído. MÉTODO: A casuística foi constituída por 39 sujeitos de 18 a 59 anos e 11 meses foram divididos em quatro grupos em função da década de vida. Estes foram submetidos à audiometria, timpanometria, testes de processamento auditivo, mini exame do estado mental, autorrelato da percepção auditiva com o Pt-AIADH e a um teste de sentenças no silêncio e no ruído. RESULTADOS: Todos os grupos pontuaram para os domínios do Pt-AIADH, com maior pontuação média para o domínio de inteligibilidade no ruído. Houve diferenças entre o G18 vs G40, G18 vs G50, e G30 vs G50 para a autopercepção auditiva na inteligibilidade no ruído; e diferenças entre o G18 e os demais grupos no teste de fala com ruído, com menor relação sinal-ruído para os adultos mais velhos. Houve correlação moderada e significativa para a inteligibilidade no ruído e o teste de fala no ruído. CONCLUSÃO: Normo-ouvintes de todas as faixas etárias estudadas apresentaram queixa de inteligibilidade no ruído. Quanto maior a dificuldade auditiva neste domínio pior o desempenho no teste de fala com ruído, sendo mais significativo em adultos de meia idade.

Does the Number of Stimuli Influence the Formation of the Endogenous Components of the Event-Related Auditory Evoked Potentials?

Introduction The number of stimuli is important to determine the quality of auditory evoked potential records. However, there is no consensus on that number in studies, especially in the sample studied. Objectives To investigate the influence of the number of rare stimuli on forming N2 and P3 components, with different types of acoustic stimuli. Methods Cross-sectional, descriptive, comparative study, approved by the ethics committee of the institution. The sample comprised 20 normal hearing adults of both sexes, aged 18 to 29 years old, with normal scores in the mental state examination and auditory processing skills. The event-related auditory evoked potentials were performed with nonverbal (1 kHz versus 2 kHz) and verbal stimuli (/BA/ versus /DA/). The number of rare stimuli varied randomly in the recordings, with 10, 20, 30, 40, and 50 presentations. Results P3 latency was significantly higher for nonverbal stimuli with 50 rare stimuli. N2 latency did not show any difference between the type and number of stimuli. The absolute P3 and N2-P3 amplitudes showed significant differences for both types of stimuli, with higher amplitude for 10 rare stimuli, in contrast with the other ones. The linear tendency test indicated significance only for the amplitude - as the number of rare stimuli increased, the amplitude tended to decrease. Conclusion The components were identifiable in the different numbers of rare stimuli and types of stimuli. The P3 and N2-P3 latency and amplitude increased with fewer verbal and nonverbal stimuli. Recording protocols must consider the number of rare stimuli.

PURPOSE: To identify the behavioral tests used to assess auditory processing throughout adulthood, focusing on the characteristics of the target population as an interest group. RESEARCH STRATEGIES: PubMed, CINAHL, Web of Science, and Scielo, databases were searched with descriptors: "auditory perception" or "auditory perception disorders" or "auditory processing" or "central auditory processing" or "auditory processing disorders" or "central auditory processing disorders" with adults OR aging. SELECTION CRITERIA: Studies with humans included, the adult population from 18 to 64 years old, who performed at least one behavioral test to assess auditory processing in the absence of hearing loss. DATA ANALYSIS: Data extraction was performed independently, using a protocol developed by the authors that included different topics, mainly the behavioral auditory tests performed and the results found. RESULTS: Of the 867 records identified, 24 contained the information needed to answer the survey questions. CONCLUSION: Almost all studies were conducted verify performance in one or two auditory processing tests. The target target population was heterogeneous, with the most frequent persons with diabetes, stuttering, auditory processing disorder, and noise exposure. There is little information regarding benchmarks for testing in the respective age groups.

Há poucas informações sobre os padrões de referência para os testes na respectiva faixa etária.

Auditory Outcomes in Adolescents with Prenatal Alcohol Exposure.

The aim of the study was to investigate three aspects of auditory function (auditory acuity, cochlear dysfunction, and auditory processing) in adolescents with fetal alcohol exposure without phenotypic changes. Fifty-one adolescents with and without intrauterine exposure to alcohol were selected from a cohort study. The summons, evaluation, and analysis of the results were carried out blindly regarding the respective exposure to alcohol. The auditory tests were pure-tone audiometry, transient otoacoustic emissions, and behavioral assessment of auditory processing (speech-in-noise, dichotic digits, and gap-in-noise). After testing, 45 adolescents were included in the evaluation and were divided into exposed (n = 22) and non-exposed (n = 23) groups. Hearing loss was identified in one subject in the exposed group (4.5%). In the absence of hearing loss, there were no significant differences in tonal thresholds or in the magnitudes of the sensory (cochlear) responses between groups (p > 0.05). There was also no difference between the two groups regarding performance on the processing tests (speech-in-noise p = 0.71, dichotic p = 0.94, and gap-in-noise p = 0.33). However, the exposed group had more cases of hearing disorders (hearing loss plus auditory processing disorders) than the non-exposed group (22.7% vs. 4.3%).

Cortical auditory evoked potentials with different acoustic stimuli: Evidence of differences and similarities in coding in auditory processing disorders.

OBJECTIVES: The use of cortical auditory evoked potentials allows for the study of the processing of acoustic signals at the cortical level, an important step in the diagnostic evaluation process, and for the monitoring of the therapeutic process associated with auditory processing disorders (APD). The differences and similarities in the acoustic coding between different types of stimuli in the context of APD remain unknown to this date. METHODS: A total of 37 children aged between 7 and 11 years, with and without APDs (identified based on verbal and non-verbal tests), all with a suitable intelligence quotient with respect to their chronological age, were assessed. Components P1 and N1 were studied using verbal and non-verbal stimuli. RESULTS: The comparison between stimuli in each group revealed that the control group had higher latency and amplitude values for speech stimuli, except for the P1 amplitude, while the group with APDs had different results with respect to the amplitudes of P1 and N1, yielding higher values for speech sounds. The differences between the groups varied according to the type of stimulus: the difference was in amplitude for the verbal stimulus and latency for the non-verbal stimulus. CONCLUSION: The records of components P1 and N1 revealed that the children with APDs performed the coding underlying the detection and identification of acoustic signals, whether verbal and non-verbal, according to a different pattern than the children in the control group.

Differential Cortical Pattern in Auditory Task Oddball Paradigm in Children Exposed to Alcohol during Pregnancy.

The negative effects of fetal alcohol exposure on child development are well documented. This study investigated the electrophysiological processing of cortical level acoustic signals in a group of 21 children prenatally exposed to alcohol. Participants aged 13-14 years at the time of the study were recruited from a longitudinal cohort sample. The study employed an observational, cross-sectional blind design and participants were divided into two groups: with and without fetal exposure to alcohol. Neurophysiological measures recorded N1, P2, N2, P3, P3a, and P3b components using the Oddball paradigm. Our results showed that the mothers' sociodemographic conditions at the time of birth, as well as the children's birth weights were homogeneous between the groups, though the Apgar score was lower in the exposed group (EG). The neurophysiological components that showed different results in the groups were P2 and P3a. P2 amplitude was higher in the midline central electrode (Cz) compared to the midline parietal electrode (Pz), demonstrating a group interaction for exposed children. For P3a there was an interaction of group and electrode position, and the EG showed higher amplitudes in Cz compared to the unEG. However, the Apgar score did not influence these results. In conclusion, children who had fetal exposure to alcohol presented electrophysiological recordings distinct from the control group. These differences occurred both in the P2 component - which reflects a bottom-up mechanism of auditory processing - as well as the P3a component, which may reflect the participation of supra-modal hearing mechanisms.

Cross-cultural adaptation of the Amsterdam inventory for auditory disability and handicap to Brazilian Portuguese / Adaptação transcultural do Amsterdam inventory for auditory disability and handicap para o português do Brasil

Abstract Introduction Patient-reported outcome measures, inventory and or questionnaire, allow patients to present their perspective of the impact of their individual condition on a day-to-day basis, independent of the analysis of test results by the expert clinician. Outcome measures are recommended when there is evidence showing their reliability, validity and sensitivity. There are standardized patient-reported outcome measures for hearing in English language; however, other languages lack these instruments. Objective Adapt the Amsterdam inventory for auditory disability and handicap to Brazilian Portuguese and analyze its validation measures. Methods We conducted two studies. In Study 1, we translated and adapted the Amsterdam inventory for auditory disability and handicap to Brazilian Portuguese according to good practice guidelines; this included the pre-test stage. In Study 2, we administered the Portuguese version to adults with and without hearing loss (n = 31 and 18, respectively) and analyzed the measures of instrument validation, reliability, and reproducibility. Moreover, we calculated the correlation between pure tone thresholds and scores on the questionnaire. Results The results obtained in Study 1 demonstrated the feasibility of the translation process and the instrument's cultural adaptation, as well as its applicability, resulting in the Portuguese version of the Amsterdam inventory for auditory disability and handicap. In Study 2, the results revealed construct values for the questions and domains, as well as for the total reliable score. The intra-interviewer test-retest condition showed excellent reproducibility (ICC = 0.97). Finally, there was a strong positive correlation (r = 0.83) between the mean pure tone threshold and the hearing difficulties values, as measured by the instrument's scores. Conclusion The English version of the Amsterdam inventory for auditory disability and handicap could be translated and adapted to Brazilian Portuguese. An analyses of the validation process yielded reliable, consistent, and stable results.

Differences and similarities in the long-latency auditory evoked potential recording of P1-N1 for different sound stimuli / Diferenças e similaridades no registro do potencial evocado auditivo P1-N1 para distintos estímulos sonoros

ABSTRACT Purpose: this study aimed at illustrating the similarities and differences in the recording of components P1 and N1 for verbal and non-verbal stimuli, in an adult sample population, for reference purposes. Methods: twenty-one adult, eutrophic individuals of both sexes were recruited for this study. The long-latency auditory evoked potential was detected by bilateral stimulation in both ears, using simultaneous recording, with non-verbal stimuli and the syllable /da/. Results: for non-verbal and speech stimuli, N1 was identified in 100.0% of the participants, whereas P1 was observed in 85.7% and 95.2% individuals for non-verbal and speech stimuli, respectively. Significant differences were observed for the P1 and N1 amplitudes between the ears (p <0.05); the P1 component, in the left ear, was higher than that in the right ear, whereas the N1 component was higher in the right one. Regarding the stimuli, the amplitude and latency values of N1 were higher for speech, whereas in P1, different results were obtained only in latency. Conclusion: the N1 component was the most frequently detected one. Differences in latency and amplitude for each stimuli occurred only for N1, which can be justified by its role in the process of speech discrimination.

RESUMO Objetivo: caracterizar as similaridades e diferenças do registro das componentes P1 e N1 para os estímulos verbal e não verbal, em uma população adulta, para fins de referência. Métodos: foram estudados 21 sujeitos adultos jovens, eutróficos, de ambos os sexos. O potencial evocado auditivo de longa latência foi pesquisado com estimulação bilateral e registro simultâneo das duas orelhas, com o estímulo clique e a sílaba /da/. Resultados: a N1 foi identificada em 100,0% da população, para os estímulos clique e fala, enquanto que a P1 foi observada em 85,7% e 95,2% dos sujeitos, para os respectivos estímulos. Foram observadas diferenças significantes para a amplitude de P1 e N1 entre as orelhas (p <0.05), sendo na P1 os valores da esquerda superiores à direita e para N1 foi o inverso. Entre os estímulos os valores de amplitude e latência da N1 foram maiores para a fala, enquanto na P1, apenas a latência obteve resultados distintos. Conclusão: a componente N1 foi a mais frequente. Apenas para N1 a diferença entre os tipos de estímulos ocorreram para latência e amplitude, o que pode ser justificado pelo seu papel no processo da discriminação de fala.

Association between the Unterberger-Fukuda test and vectoelectronystagmography / Associação entre a prova de Unterberger-Fukuda e o exame de vectoeletronistagmografia

ABSTRACT Purpose: to study and characterize anteroposterior and angular deviations in the Unterberger-Fukuda Test (UFT) in relation to the results of the caloric tests in patients complaining of dizziness or vertigo. Methods: 44 subjects-men and women between 20 and 79 years of age-who had symptoms of vertigo or dizziness and had been referred for vectoelectronystagmography were examined. The exclusion criteria were gait difficulties arising from orthopedic and/or spinal disorders, and syndromes or neurological diseases that affect balance. Two procedures were performed: vectoelectronystagmography and UFT. Results: the caloric test showed that 25.00% of the patients had hyporeflexia-the most frequent result. In the open-eyes UFT, only 2.30% presented altered results in anteroposterior displacement. In the closed-eyes test, the equivalent value was 31.80%. Anteroposterior deviation showed a greater correlation with age than the angular one. Abnormal results in the caloric test were associated with the UFT. Conclusion: the results of the closed-eyes UFT were associated with the caloric test. Anteroposterior deviation was correlated with age, while angular deviation was not.

RESUMO Objetivo: estudar e caracterizar os desvios anteroposteriores e angulares da Prova de Unterberger-Fukuda (PUF) em função do resultado da prova calórica, em sujeitos com queixa de tontura e ou vertigem. Métodos: foram avaliados 44 sujeitos, de ambos os sexos, com idade entre 20 a 79 anos, com queixa de vertigem e ou tontura, encaminhados para exame de vectoeletronistagmografia. Os critérios de exclusão foram a identificação de dificuldades de marcha decorrentes de alterações ortopédicas e ou de coluna, assim como síndromes e doenças neurológicas que afetam o equilíbrio. Foram realizados dois procedimentos, a PUF e o exame de vectonistagmografia. Resultados: na prova calórica o tipo de alteração mais frequente foi a hiporreflexia 25,00%, da casuística total. Para o resultado da PUF apenas 2,30% apresentou resultados alterados no deslocamento anteroposterior, de olhos abertos, na etapa de olhos fechados o mesmo tipo de ocorrência foi de 31,80%. O desvio anteroposterior mostrou maior correlação com o aumento da idade, em relação ao do tipo angular. Houve associação entre os resultados alterados na prova calórica e a PUF. Conclusão: os resultados da PUF de olhos fechados apresentaram associação com a prova calórica, o desvio do tipo anteroposterior esteve correlacionado ao aumento da idade, o angular não.

What we know of the central auditory disorders in children exposed to alcohol during pregnancy? Systematic review. / O que sabemos das alterações auditivas centrais em crianças expostas ao álcool na gestação? Revisão sistemática.

PURPOSE: To identify the effects of alcohol intake during pregnancy on the central auditory nervous system in relation to their possible diagnosis, Fetal Alcohol Syndrome, partial Fetal Alcohol Syndrome, Alcohol-Related Birth Defects and Alcohol-Related Neurodevelopmental Disorder, his extension and the hearing assessment method. RESEARCH STRATEGY: Systematic and integrative review searched the databases PubMed, LILACS and SciELO, with terms in Portuguese and English "fetal alcohol syndrome", "alcohol-related disorders" associated with "hearing". Selection criteria: We identified 123 abstracts, six were selected and published until May 2015. DATA ANALYSIS: Were listed topics to be answered, characterization of the sample; the diagnosis result of fetal exposure; method of hearing assessment and described results. RESULTS: Among the behavioral assessments, Verbal Dichotic Tests with syllables and sentences and Speech in Noise Test, were used. Among the electrophysiological tests, the Brainstem Auditory Evoked Potential was detected change neural synchrony, and Long-Latency Auditory Evoked Potential - P300, early latency values. CONCLUSION: There is evidence that children exposed to alcohol in utero present central auditory nervous system involvement signals, but it was not possible to identify the influence of different subtypes and their losses. Cortical auditory pathways were the most investigated and the electrophysiological method as used with an unexpected result in two of them, early N2 and P300 latency.

RESUMO Objetivo Identificar os efeitos da ingestão de álcool na gestação sobre o sistema nervoso auditivo central em relação aos seus possíveis diagnósticos, Síndrome Fetal do Álcool, Síndrome Fetal do Álcool Parcial, Distúrbios ao Nascimento Relacionados ao Álcool e Distúrbio do Neurodesenvolvimento Relacionado ao Álcool, sua extensão e o método de avaliação auditiva. Estratégia de pesquisa Busca sistemática e integrativa nas bases de dados PubMed, LILACS e SciELO, com os termos em português e inglês “síndrome fetal do álcool”, “desordens relacionadas ao uso do álcool” associadas a “audição”. Critérios de seleção Dos 123 resumos identificados, foram seis selecionados, publicados até maio de 2015. Análise dos dados Foram elencados tópicos a serem respondidos, caracterização da casuística; o diagnóstico decorrente da exposição fetal nas crianças; método de avaliação auditiva; e resultados descritos. Resultados Entre as avaliações comportamentais, foram utilizados os testes dicóticos verbais com sílabas e com sentenças e o teste fala com ruído. Entre os testes eletrofisiológicos, no Potencial Evocado Auditivo de Tronco Encefálico, foi detectada alteração de sincronia neural, e no Potencial Evocado Auditivo de Longa Latência – P300, valores de latência precoces. Conclusão Existem evidências de que as crianças e adultos jovens expostos ao álcool na gestação apresentam sinais de comprometimento do sistema nervoso auditivo central, mas não foi possível caracterizar essas alterações nos diferentes subtipos diagnósticos do espectro. As vias auditivas corticais foram as mais investigadas e o método eletrofisiológico o mais utilizado, com um resultado inesperado em dois deles, a latência precoce da N2 e da P300.

Variables in P300 recording: task type and electrode position.

PURPOSE: To analyze the latency and amplitude of P300 responses obtained with electrodes positioned at Cz and Fz and in different tasks of infrequent stimulus identification in normal hearing individuals. METHODS: Forty adults of both genders participated in the study. Three recordings with three different tasks were obtained for the identification of the infrequent stimulus; simultaneous recordings were obtained from Cz and Fz positions. RESULTS: Cz position showed significantly greater amplitudes and lower latencies than Fz. Regarding the three tasks, only "pronouncing the word 'thin'" was different from "raising a finger", with lowest latencies for the verbal task. Regarding amplitude, significantly higher values were observed for "raising a finger", followed by "pronouncing the word 'thin'" and mental counting. CONCLUSION: Cz obtained the best values, highest amplitude and lowest latency. Lowest latencies were obtained for the task of "pronouncing the word 'thin'" and the highest amplitudes were obtained for "raising a finger".

What Can We Learn about Auditory Processing from Adult Hearing Questionnaires?

BACKGROUND: Questionnaires addressing auditory disability may identify and quantify specific symptoms in adult patients with listening difficulties. PURPOSE: (1) To assess validity of the Speech, Spatial, and Qualities of Hearing Scale (SSQ), the (Modified) Amsterdam Inventory for Auditory Disability (mAIAD), and the Hyperacusis Questionnaire (HYP) in adult patients experiencing listening difficulties in the presence of a normal audiogram. (2) To examine which individual questionnaire items give the worse scores in clinical participants with an auditory processing disorder (APD). RESEARCH DESIGN: A prospective correlational analysis study. STUDY SAMPLE: Clinical participants (N = 58) referred for assessment because of listening difficulties in the presence of normal audiometric thresholds to audiology/ear, nose, and throat or audiovestibular medicine clinics. Normal control participants (N = 30). DATA COLLECTION AND ANALYSIS: The mAIAD, HYP, and the SSQ were administered to a clinical population of nonneurological adults who were referred for auditory processing (AP) assessment because of hearing complaints, in the presence of normal audiogram and cochlear function, and to a sample of age-matched normal-hearing controls, before the AP testing. Clinical participants with abnormal results in at least one ear and in at least two tests of AP (and at least one of these tests to be nonspeech) were classified as clinical APD (N = 39), and the remaining (16 of whom had a single test abnormality) as clinical non-APD (N = 19). RESULTS: The SSQ correlated strongly with the mAIAD and the HYP, and correlation was similar within the clinical group and the normal controls. All questionnaire total scores and subscores (except sound distinction of mAIAD) were significantly worse in the clinical APD versus the normal group, while questionnaire total scores and most subscores indicated greater listening difficulties for the clinical non-APD versus the normal subgroups. Overall, the clinical non-APD group tended to give better scores than the APD in all questionnaires administered. Correlation was strong for the worse-ear gaps-in-noise threshold with the SSQ, mAIAD, and HYP; strong to moderate for the speech in babble and left-ear dichotic digit test scores (at p < 0.01); and weak to moderate for the remaining AP tests except the frequency pattern test that did not correlate. The worse-scored items in all three questionnaires concerned speech-in-noise questions. This is similar to worse-scored items by hearing-impaired participants as reported in the literature. Worse-scored items of the clinical group also included quality aspects of listening questions from the SSQ, which most likely pertain to cognitive aspects of listening, such as ability to ignore other sounds and listening effort. CONCLUSIONS: Hearing questionnaires may help assess symptoms of adults with APD. The listening difficulties and needs of adults with APD to some extent overlap with those of hearing-impaired listeners, but there are significant differences. The correlation of the gaps-in-noise and duration pattern (but not frequency pattern) tests with the questionnaire scores indicates that temporal processing deficits may play an important role in clinical presentation.
