- ItemAcesso aberto (Open Access)Audiometria de reforço visual com diferentes estímulos sonoros em crianças ouvintes e deficientes auditivas: estudo comparativo(Universidade Federal de São Paulo (UNIFESP), 2006-12-31) Vieira, Eliara Pinto [UNIFESP]; Azevedo, Marisa Frasson de [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Objetivo: Verificar os Níveis Mínimos de Respostas (NMR) através de Audiometria de Reforço Visual (ARV) em campo livre, em 50 crianças ouvintes e 25 deficientes auditivos, considerando as variáveis: lado de apresentação sonora, sexo, idade e tipo de estímulo. Método: Realizou-se ARV com tons puros modulados e com Sistema Sonar. Resultados: Não houve diferença estatisticamente significante entre MNR em relação ao lado de apresentação. Os NMR em 500 e 2000Hz do Sistema Sonar, foram menores no sexo masculino nos ouvintes. Neste grupo houve diminuição dos NMR com aumento da idade, para ambos estímulos. Ao comparar NMR com os dois estímulos houve diferença estatisticamente significante a favor do Sistema Sonar apenas para ouvintes com menos de dois anos. Conclusão: Em ouvintes os NMR reduzem com avanço da idade independente do estímulo, porém estes são inferiores com o Sistema Sonar. Nos deficientes auditivos não houve diferença significativa em relação a nenhuma variável estudada.
- ItemAcesso aberto (Open Access)Avaliação do processamento auditivo em crianças nascidas pré-termo(Sociedade Brasileira de Fonoaudiologia, 2011-01-01) Gallo, Julia [UNIFESP]; Dias, Karin Ziliotto [UNIFESP]; Pereira, Liliane Desgualdo [UNIFESP]; Azevedo, Marisa Frasson de [UNIFESP]; Sousa, Elaine Colombo [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)PURPOSE: To verify the performance of children born preterm on auditory processing evaluation, and to correlate the data with behavioral hearing assessment carried out at 12 months of age, comparing the results to those of auditory processing evaluation of children born full-term. METHODS: Participants were 30 children with ages between 4 and 7 years, who were divided into two groups: Group 1 (children born preterm), and Group 2 (children born full-term). The auditory processing results of Group 1 were correlated to data obtained from the behavioral auditory evaluation carried out at 12 months of age. The results were compared between groups. RESULTS: Subjects in Group 1 presented at least one risk indicator for hearing loss at birth. In the behavioral auditory assessment carried out at 12 months of age, 38% of the children in Group 1 were at risk for central auditory processing deficits, and 93.75% presented auditory processing deficits on the evaluation. Significant differences were found between the groups for the temporal order test, the PSI test with ipsilateral competitive message, and the speech-in-noise test. The delay in sound localization ability was associated to temporal processing deficits. CONCLUSION: Children born preterm have worse performance in auditory processing evaluation than children born full-term. Delay in sound localization at 12 months is associated to deficits on the physiological mechanism of temporal processing in the auditory processing evaluation carried out between 4 and 7 years.
- ItemAcesso aberto (Open Access)Avaliação dos comportamentos auditivos de figura-fundo e de resolução temporal e da percepção de limitações de atividades comunicativas em crianças e adolescentes portadores de deficiência auditiva unilateral(Universidade Federal de São Paulo (UNIFESP), 2010-01-27) Vieira, Márcia Ribeiro [UNIFESP]; Pereira, Liliane Desgualdo [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Purpose: To test the hearing behavior of figure-to-ground and temporal resolution and the self-perception of limitations on activities of children and adolescents with unilateral hearing loss. Methods: Participated 38 individuals, between the age of 8 and 19 (average 12.32), divided into: experimental group (with unilateral hearing loss) and control group (normal-hearing individuals), each one formed of 19 individuals, matched according to their gender, age and educational level. They have all been submitted to anamneses, to a complete audiology test and to the procedures of study: a self-report questionnaire of limitations on communicative activities with questions about noisy and silent situations, and sound localization. The participants have been submitted to the Gap-In-Noise and the Pediatric Speech Intelligibility tests at 0, -10 and -15 reference. The statistical analysis has been done through non-parametric tests at the significance level of 0.05. Results: In the experimental group the unilateral hearing loss has been classified as profound in most participants, having started at the pre-schooling stage, with unknown or undefined etiologies (e.g. meningitis, traumas, mumps and measles). Most individuals have presented complaints of learning difficulties, and have shown limitations on communicative activities, of moderate degree predominantly, and especially in noisy situations. The degree and the ear with unilateral hearing loss have not interfered in the severity of the limitation. The worst results, both at the thresholds of gap detection and the Pediatric Speech Intelligibility test on the good ear, have been found in the experimental group. There was no correlation between the thresholds of gap detection on the good ear and the side of the bad one. Conclusions: Individuals with unilateral hearing loss present limitations on communicative activities, especially in noisy environments which are related to worse hearing abilities of temporal resolution and figure-to-ground.
- ItemSomente MetadadadosDos limiares de audibilidade nas alta frequências em pacientes com insuficiência renal crônica submetido ao tratamento conservador(Universidade Federal de São Paulo (UNIFESP), 2000) Zeigelboim, Bianca Simone [UNIFESP]; Mangabeira-Albernaz, Pedro Luiz [UNIFESP]O presente estudo, teve como objetivo, investigar o comportamento auditivo nas altas frequencias de 9000 ate 18000 Hz, em pacientes com insufiCiência renal cronica submetidos ao tratamento conservador, no periodo de um ano, comparados com um grupo controle da mesma faixa etaria. A amostra estudada, constou de 133 individuos classificados em dois grupos: controle e conservador. O grupo controle, compreendeu 96 individuos, sendo 34 do sexo masculino e 62 do sexo feminino. O grupo conservador, constou de 37 pacientes renais cronicos, sendo 19 do sexo masculino e 18 do sexo feminino. A faixa etaria estudada foi de 30 a 59 anos em ambos os grupo Realizaram-se em ambos os grupos, os seguintes procedimentos: otoscopia, avaliacao audiologica basica e audiometria de altas frequencias. Da analise do grupo controle, observou-se que: a) nao houve diferenca significante dos limiares de audibilidade com relacao as variaveis lado e sexo, em todas as faixas etarias estudadas e frequencias testadas; b) notou-se que com o aumento das frequencias, o numero de individuos capazes de responder em cada grupo etario diminuiu e c) verificou-se um declinio da sensibilidade auditiva com o avanco da idade em todas as faixas etarias estudadas. Comparando os dados obtidos no grupo controle com o grupo conservador (1ª e 2ª avaliacoes), verificou-se, um declinio da sensibilidade auditiva em todas as faixas etarias estudadas principalmente com relacao a 2a avaliacao, sendo esta, mais acentuada na faixa etaria de 50 a 59 anos. Com isso, verificou-se que a audiometria de altas frequencias e um importante recurso, nao so para a deteccao precoce da perda auditiva, como de seu monitoramento
- ItemAcesso aberto (Open Access)Elaboração da versão em Português Brasileiro do teste de identificação de sentenças dicóticas (DSI)(Sociedade Brasileira de Fonoaudiologia, 2010-12-01) Andrade, Adriana Neves de [UNIFESP]; Gil, Daniela [UNIFESP]; Iorio, Maria Cecilia Martinelli [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)PURPOSE: To develop the Brazilian Portuguese version of the dichotic sentence idenfication test (DSI). METHODS: The sentences used in the Portuguese version of DSI test were extracted from the Synthetic Sentece Identification (SSI) test in Portuguese. A method of combination was used in order to create 45 pairs of sentences, each pair corresponding to a test item. The items were divided into five groups, each group corresponding to a specific test condition. For this purpose, a computer program was designed in the Matlab 7.0 computing platform, using the Monte Carlo method, or the brute force method, for the distribution of items in each group. The sentences were edited, recorded and finalized; for manipulation of data it was used the CaKewalk Sonar 2.2 program. Finally, the Sound Forge program was used for finalization and standardization of the recording. RESULTS: As a result, a compact disc with six tracks was obtained to be used as part of the behavioral assessment of auditory processing, including the following tracks: calibration, practice, binaural integration, directed attention to the right and to the left ears. The use of the calibration and auditory training tracks is recommended for use in the rehabilitation of auditory processing disorders. CONCLUSION: The compact disc with the Brazilian Portuguese version of the DSI test consisted of six tracks: calibration, practice, binaural integration, directed attention to the right and to the left ears and auditory training.
- ItemAcesso aberto (Open Access)A influência dos aspectos cognitivos e dos processos auditivos na aclimatização das próteses auditivas em idosos(Sociedade Brasileira de Fonoaudiologia, 2012-01-01) Pinheiro, Maria Madalena Canina [UNIFESP]; Iorio, Maria Cecilia Martinelli [UNIFESP]; Miranda, Elisiane Crestani [UNIFESP]; Dias, Karin Ziliotto [UNIFESP]; Pereira, Liliane Desgualdo [UNIFESP]; Universidade Federal de Santa Catarina; Universidade Federal de São Paulo (UNIFESP); Santa Casa de São Paulo Faculdade de Ciências MédicasPURPOSE: To verify the speech recognition processes in a monoaural task and in a binaural integration task with dichotic listening, and to compare them to the cognitive processing in elderly subjects pre and post hearing aid acclimatization. METHODS: Participants were 60 elderly subjects of both genders, ranging in age from 61 to 85 years. They were evaluated for cognitive aspects by means of the Mini-Mental State Examination (MMSE) and the Alzheimer's Disease Assessment Scale (ADAS-Cog). To evaluate speech processes in a monoaural task and in a binaural integration task with dichotic listening, the Percentage Index of Speech Recognition Test (PISR) and the Dichotic Digits Test (DDT) were completed before and after using the hearing aid. Data was descriptively presented and compared with non-parametric tests. RESULTS: Speech recognition at the PISR was low (mean 69.6%) and the DDT presented better digit recognition on the right ear (mean 74.1%) than on the left ear (mean 61.1%). The sample presented improved performance on speech tests after the use of hearing aids, with relevant difference between the means of the first and the second evaluations. The PISR was not correlated with cognitive aspects. The DDT was associated with both cognitive tests, especially for the left ear. CONCLUSION: All subjects were acclimatized, because there was improvement in speech recognition following the use of hearing aids. Subjects with cognitive problems present poorer performance in speech recognition processes with dichotic listening.
- ItemAcesso aberto (Open Access)Percepção de limitações de atividades comunicativas, resolução temporal e figura-fundo em perda auditiva unilateral(Sociedade Brasileira de Fonoaudiologia, 2011-12-01) Vieira, Márcia Ribeiro [UNIFESP]; Nishihata, Regiane [UNIFESP]; Chiari, Brasilia Maria [UNIFESP]; Pereira, Liliane Desgualdo [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)PURPOSE: To evaluate the hearing behavior of figure-to-ground and temporal resolution, and the self-perception of limitations on communicative activities of children and adolescents with unilateral hearing loss. METHODS: Participants were 38 individuals, with ages between 8 and 19 years, divided into: experimental group (with unilateral hearing loss) and control group (normal-hearing individuals), each comprising 19 individuals, matched according to gender, age and educational level. All subjects carried out anamnesis, audiological evaluation, and the procedures of study: a self-report questionnaire of limitations on communicative activities, and the auditory processing tests Gaps-in-Noise and Pediatric Speech Intelligibility Test. Statistical analysis was conducted using non-parametric tests. RESULTS: In the experimental group the unilateral hearing loss was profound in most participants, having started during the pre-school stage, with unknown or identified etiologies (e.g. meningitis, traumas, mumps and measles). Most subjects presented learning difficulties complaints, and showed predominantly moderate limitations on communicative activities, mainly in noisy situations. The worst results were observed in the experimental group, both for the thresholds of gap detection and the Pediatric Speech Intelligibility Test carried out in the normal ear. There was no significant correlation between the thresholds of gap detection on the normal ear and the side of the ear with hearing loss. CONCLUSION: Individuals with unilateral hearing loss present limitations on communicative activities, especially in noisy environments, associated with worse auditory processing abilities of temporal resolution and figure-to-ground.
- ItemSomente MetadadadosProcessamento auditivo em idosos(Universidade Federal de São Paulo (UNIFESP), 2004) Pinheiro, Maria Madalena Canina [UNIFESP]; Pereira, Liliane Desgualdo [UNIFESP]Objetivo: Caracterizar o aspecto da interacao de sons verbais e nao verbais em idosos com e sem perda auditiva por meio dos testes de Fusao Binaural (FB), Localizacao Sonora em Cinco Direcoes (LS), Lateralizacao Temporal (LT) e do Teste Pediatrico de Inteligibilidade da Fala em escuta Monotica (Pediatric Sentence Identification-PSIMCI),levando em conta cada procedimento, grau e configuracao da perda auditiva. Metodos: 110 idosos, 88 do sexo feminino e 22 do sexo masculino, na faixa etaria dos 60 a 85 anos com audicao normal ou com perda auditiva neurossensorial de grau ate moderadamente-severo, simetrica foram incluidos neste estudo. Os audiogramas possibilitaram a classificacao em grupos quanto ao grau e quanto a configuracao audiometrica da perda auditiva. O comportamento auditivo comum a todos os testes selecionados foi denominado de interacao. A analise foi feita por procedimento isolado, combinado e por grupos do grau e da configuracao audiometrica. Resultados: Ocorreram mais individuos com inabilidade no teste de FB do que no teste de LS. Ao aumentarmos a intensidade da competicao o desempenho do idoso piora no teste PSIMCI. Os resultados por orelha sao semelhantes do teste de LT, entretanto ocorreu uma tendencia da tecnica ascendente apresentar um indice de lateralizacao menor do que a descendente. No estudo combinado dos procedimentos houve uma dependencia estatisticamente significante entre o teste de LS com o de LT e entre o teste de FB com o teste PSI-MCI. Os procedimentos que apresentaram uma dependencia estatisticamente significante com os grupos do grau foram o teste de LS, teste LT e PSI-MCI (-10). O teste de LS apresentou dependencia estatisticamente significante com os grupos da configuracao audiometrica. O grupo com perda auditiva apenas em frequencias altas (GFA) foi o que apresentou menores indices de lateralizacao e se diferenciou estatisticamente dos demais grupos da configuracao Conclusao: Idosos apresentam dificuldade no processo de interacao binaural quando a informacao auditiva nao esta completa. O grau da perda auditiva interferiu principalmente nos comportamentos auditivos de localizacao e lateralizacao. A configuracao audiometrica interferiu no comportamento auditivo de localizacao. Ainda, para o indice de lateralizacao temporal houve interferencia da configuracao com perda auditiva em frequencias baixas e medias
- ItemAcesso aberto (Open Access)Processamento temporal, localização e fechamento auditivo em portadores de perda auditiva unilateral(Sociedade Brasileira de Fonoaudiologia, 2012-01-01) Nishihata, Regiane [UNIFESP]; Vieira, Márcia Ribeiro [UNIFESP]; Pereira, Liliane Desgualdo [UNIFESP]; Chiari, Brasilia Maria [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)PURPOSE: To assess the behaviors of temporal resolution and temporal ordering, sound localization, and auditory closure, and to investigate possible associations with complaints of learning, communication and language difficulties in individuals with unilateral hearing loss. METHODS: Participants were 26 individuals with ages between 8 and 15 years, divided into two groups: Unilateral hearing loss group; and Normal hearing group. Each group was composed of 13 individuals, matched by gender, age and educational level. All subjects were submitted to anamnesis, peripheral hearing evaluation, and auditory processing evaluation through behavioral tests of sound localization, sequential memory, Random Detection Gap test, and speech-in-noise test. Nonparametric statistical tests were used to compare the groups, considering the presence or absence of hearing loss and the ear with hearing loss. RESULTS: Unilateral hearing loss started during preschool, and had unknown or identified etiologies, such as meningitis, traumas or mumps. Most individuals reported delays in speech, language and learning developments, especially those with hearing loss in the right ear. The group with hearing loss had worse responses in the abilities of temporal ordering and resolution, sound localization and auditory closure. Individuals with hearing loss in the left ear showed worse results than those with hearing loss in the right ear in all abilities, except in sound localization. CONCLUSION: The presence of unilateral hearing loss causes sound localization, auditory closure, temporal ordering and temporal resolution difficulties. Individuals with unilateral hearing loss in the right ear have more complaints than those with unilateral hearing loss in the left ear. Individuals with hearing loss in the left ear have more difficulties in auditory closure, temporal resolution, and temporal ordering.
- ItemAcesso aberto (Open Access)Scale of Auditory Behaviors e testes auditivos comportamentais para avaliação do processamento auditivo em crianças falantes do português europeu(Sociedade Brasileira de Fonoaudiologia, 2013-01-01) Nunes, Cristiane Lima; Pereira, Liliane Desgualdo [UNIFESP]; Carvalho, Graça Simões De; Universidade do Minho Instituto de Educação Centro de Investigação em Estudos da Criança; Universidade Federal de São Paulo (UNIFESP)PURPOSE: The objective of this research was to assess the auditory abilities of Portuguese children and compare such abilities to the score of the Scale of Auditory Behaviors (SAB). METHODS: Fifty-one children were evaluated with audiometry, speech audiometry, acoustic immittance measures, and eight behavioral tests involving dichotic listening, monotic listening, temporal processing, and sound localization. Their parents filled in the SAB questionnaire adapted to European A. SAB scores and auditory tests scores were submitted to Pearson's correlation coefficient. RESULTS: There is significant correlation between the score on SAB questionnaire and the auditory processing tests. The greatest coefficient was observed in temporal processing test (p=0.000). CONCLUSION: There was correlation between the score of SAB and the performance in auditory processing tests, suggesting that the SAB may be used for auditory processing screening.
- ItemAcesso aberto (Open Access)Temporal resolution with click and pure tone stimuli in youngsters with normal hearing sensitivity(Sociedade Brasileira de Fonoaudiologia, 2012-01-01) Sousa, Luciana Leal De [UNIFESP]; Dias, Karin Ziliotto [UNIFESP]; Pereira, Liliane Desgualdo [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)PURPOSE: To assess the auditory ability of temporal resolution and to compare the random gap detection test (RGDT) versions with pure tone and clicks stimuli. METHODS: Participants were 40 young individuals of both genders with ages between 18 and 25 years, and normal hearing thresholds for the sound frequencies of 250 Hz to 8 kHz. Initially, participants were submitted to the basic audiological evaluation. Then they underwent the RGDT with pure tone and clicks stimuli. Finally, we obtained the temporal acuity threshold, which corresponds to the shorter silence interval in which the patient perceives two sounds, for each type of stimulus, called final temporal acuity threshold for pure tones (mean of the thresholds obtained for 500 Hz, 1k, 2k and 4 kHz), and temporal acuity threshold for clicks. RESULTS: The mean temporal acuity threshold for the sound frequency of 500 Hz was 7.25 ms; for the frequency of 1 kHz was 7.25 ms; for 2 kHz was 6.73 ms; for the frequency of 4 kHz was 6.03 ms. The final temporal acuity threshold was 6.72 ms. The mean temporal acuity threshold for clicks was 6.43 ms. No difference was found between the temporal acuity thresholds obtained with pure tone and clicks stimuli. CONCLUSION: There is no difference in the performance of individuals on the auditory ability of temporal resolution, regardless of the auditory stimulus used.
- ItemAcesso aberto (Open Access)Teste de padrão harmônico em escuta dicótica com dígitos - TDDH(Sociedade Brasileira de Fonoaudiologia, 2007-12-01) Ríos, Alejandro Arroyo; Rezende, Alessandra Giannico De [UNIFESP]; Pela, Sandra Maria [UNIFESP]; Ortiz, Karin Zazo [UNIFESP]; Pereira, Liliane Desgualdo [UNIFESP]; Universidad de la Frontera Escola de Medicina Departamento de Especialidades Médicas; Universidade Federal de São Paulo (UNIFESP)PURPOSE: The aims of this study are the development of an auditory processing test with musical stimuli in dichotic tasks, the characterization of the performance of normal hearing subjects and the comparison between the results and those in the Digits Dichotic Test (TDD). METHODS: The auditory processing test with musical stimuli was elaborated with harmonic digits. The test was denominated Harmonic Pattern Dichotic Digits Test (TDDH) and comprised biaural integration and two stages of biaural separation (left/right), each one with 20 items made up of four harmonic digits. It was applied in 40 individuals of both sexes. They were all adults, their ages ranged from 19 to 52 years old and they spoke Brazilian Portuguese. RESULTS: The results were compared to results of the TDD applied in the same individuals. The individuals had approximately 99% success in all the stages, their performance was higher than the one observed in the TDD - stages of biaural separation. CONCLUSION: We believe that the test elaborated for this study showed applicability in normal hearing individuals. The use of musical stimuli seems to make the performance of individuals easier than the dichotic verbal tests.
- ItemAcesso aberto (Open Access)Triagem da Afinação Vocal: comparação do desempenho de musicistas e não musicistas(Sociedade Brasileira de Fonoaudiologia, 2012-01-01) Moreti, Felipe Thiago Gomes [UNIFESP]; Pereira, Liliane Desgualdo [UNIFESP]; Gielow, Ingrid [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)PURPOSE: To develop a simple and quick-to-apply procedure for pitch-matching scanning that contains vocal imitation tasks of musical sounds of different tones and the temporal ordination of three different tones; to verify its applicability, by comparing the performance of musicians and non-musicians. METHODS: Participants were 32 adults of both genders without vocal, hearing and/or auditory processing complaints. They were equally divided into two groups: musicians group - MG and non-musicians group - NMG. All participants underwent the Pitch-matching Scanning that included musical stimuli compatible with men and women singing vocal range gathered into two types of tasks: isolate tones and three-tone sequences. Participants were instructed to listen to them and to reproduce them vocally. Voice samples were recorded, analyzed acoustically, and right and wrong matches for the two tasks were characterized. The variables regarding the comparison between groups and types of tasks were statistically analyzed. RESULTS: A difference was found between groups, and the MG presented greater number of right matches in both tasks. CONCLUSION: The Pitch-matching Scanning was developed and was sensitive to evaluate and compare the performance between groups. Thus, it can be used as a tool for pitch-matching tracking. Musicians presented better performance than non-musicians in the Pitch-matching Scanning.
