PURPOSE: this study aims to assess vocal deviation in individuals with developmental stuttering. METHODS: 23 adults, 9 females and 14 males, with different degrees of stuttering (Yowa Severity Scale) mean age: 31.2 years, ranging from 23 to 45, took part in the study. Perceptual auditory analysis of vocal quality was assessed by means of GIRBAS scale, with the inclusion of extra features; selected acoustic parameters were extracted. RESULTS: vocal quality was deviated in 13% of sustained vowels samples; instability was the most prominent parameter (69.57% mild and 20% moderate deviation), followed by roughness (48.70% mild and 11.30% moderate). For connected speech, roughness was the most altered parameter (59.13% mild and 1.74% moderate), followed by inconsistent tension (46.08% mild and 3.49% moderate). The maximum phonation time measurements were variable both intra and inter-subjects. The spectrographic trace showed instability due to the presence of voice breaks (21.74%), sub-harmonics (30.43%), variable fundamental frequency (8.7%) and/or vocal quality (8.7%). Perturbation measures showed to be deviated, for both shimmer (91.30%) and jitter (34,78%). CONCLUSIONS: vocal deviations are mild in stutters, evidenced at the sustained vowel task, independently of the stuttering degree. Data suggest a phonatory system's neuromotor instability in stutters.

BACKGROUND: the voice of choir conductors. AIM: to evaluate the vocal quality of choir conductors based on the production of a sustained vowel during singing and when speaking in order to observe auditory and acoustic differences. METHOD: participants of this study were 100 choir conductors, with an equal distribution between genders. Participants were asked to produce the sustained vowel é using a singing and speaking voice. Speech samples were analyzed based on auditory-perceptive and acoustic parameters. The auditory-perceptive analysis was carried out by two speech-language pathologist, specialists in this field of knowledge. The acoustic analysis was carried out with the support of the computer software Doctor Speech (Tiger Electronics, SRD, USA, version 4.0), using the Real Analysis module. RESULTS: the auditory-perceptive analysis of the vocal quality indicated that most conductors have adapted voices, presenting more alterations in their speaking voice. The acoustic analysis indicated different values between genders and between the different production modalities. The fundamental frequency was higher in the singing voice, as well as the values for the first formant; the second formant presented lower values in the singing voice, with statistically significant results only for women. CONCLUSION: the voice of choir conductors is adapted, presenting fewer deviations in the singing voice when compared to the speaking voice. Productions differ based the voice modality, singing or speaking.

(CEFAC Saúde e Educação, 2011-10-01) Terto, Sulamita Da Silva Marcelino; Lemos, Stela Maris Aguiar [UNIFESP]; Universidade Federal de Minas Gerais Acadêmica do curso de Fonoaudiologia; Universidade Federal de São Paulo (UNIFESP)
BACKGROUND: this article was produced based on a review of articles published since 2005 in four major national journals in the fields of Speech (Pró-Fono Revista de Atualização Científica, Revista Brasileira de Otorrinolaringologia, Revista CEFAC and Revista Sociedade Brasileira de Fonoaudiologia) on the temporal aspects of hearing. This study points out to three addressed issues: temporal aspects, temporal ordering and temporal resolution. PURPOSE: to delineate the profile of knowledge production in the area of auditory temporal aspects with reference to four national journals. CONCLUSION: the survey conducted in this research showed that there is a small number of national studies related to the issue concerning the temporal aspects of hearing. Considering only the four national journals, less than 9% of the scientific production addressed this issue.

Avaliação comportamental e eletrofisiológica do processamento auditivo central em indivíduos com traumatismo cranioencefálico leve pré e pós-treinamento auditivo acusticamente controlado
(Universidade Federal de São Paulo (UNIFESP), 2019-05-28) Buriti, Ana Karina Lima [UNIFESP]; Gil, Daniela [UNIFESP]; http://lattes.cnpq.br/6363626867862971; http://lattes.cnpq.br/0641682808873805; Universidade Federal de São Paulo (UNIFESP)
Objective: To characterize and compare the behavioral and electrophysiological assessments of the central auditory processing in individuals with mild degree of traumatic brain injury, pre, post and after 6 months of acoustically controlled auditory training. Method: The sample was composed of ten individuals between 16 and 64 years after mild traumatic brain injury who underwent behavioral assessment of central auditory processing and electrophysiological assessment of hearing before and after the acomplishment of an acoustically controlled auditory training, which was organized in ten sessions. After concluding the stimulation program, we applied a self-assessment questionnaire. In order to assess the stability of the measurements, the individuals were invited to undergo a new re-assessment six months after the acoustically controlled auditory training. Results: In the behavioral assessment of central auditory processing, we noted changes in all tests, with a higher emphasis on speech in noise (90%), followed by the duration standard (80%). By comparing the pre and post assessments, we noted a statistically significant difference in the speech in noise tests in the left ear, dichotic of alternating disyllables in the right ear, sound localization and Random Gap Detecton Fusion, with better results after the acoustically controlled auditory training. In the electrophysiological assessment, we noted changes in the brain stem in the pre-assessment, besides adequacy in 100% of the individuals for wave III latency and I-III interspike interval on the right. In the assessment of the frequency following response, we noted changes in all waves due to latency delay and/or component absence, mainly for D, E, F and O waves; and after the auditory training, D and E waves on the right. For the cognitive potential, we noted a statistically significant difference for the left P3 amplitude with speech stimulus. Between the pre and post assessments, we noted P300 adequacy in 100% of the individuals on the left ear with tone burst stimulus in the post-assessment. In the self-assessment questionnaire, we noted a higher concentration of responses in a significant improvement for auditory performance aspects in noisy environments, attention and alertness level, as well as self-esteem. Conclusion: The individuals with mild traumatic brain injury show central auditory processing disorder in both behavioral and electrophysiological assessments, which was minimized after the acoustically controlled auditory training.

(Pró-Fono Produtos Especializados para Fonoaudiologia Ltda., 2010-09-01) Dutra, Marilene Danieli Simões; Cavadas, Marcia [UNIFESP]; Câmara, Volney De Magalhães; Universidade Federal do Rio de Janeiro Instituto de Estudos de Saúde Coletiva; Universidade Federal de São Paulo (UNIFESP); Universidade Federal do Rio de Janeiro Instituto de Estudos em Saúde Coletiva Faculdade de Medicina
BACKGROUND: central auditory processing and exposure to metallic mercury. AIM: to evaluate the performance on tests of central auditory processing in adolescents exposed to metallic mercury. METHOD: participants were 52 adolescents, of both genders, who presented hearing thresholds within normal limits. The study group (SG) was composed by 21 adolescents who worked on the burning of gold-mercury amalgams, on the re-burning of gold in stores that sell this metal or who lived next to gold mines or gold shops. The control group (CG) was composed by 31 adolescents who had no history of exposure to mercury. Investigation procedures included the application of a clinical, occupational and mercury exposure history questionnaire, basic audiometric assessment as well as central auditory processing tests. RESULTS: Statistical significant differences in the auditory processing tests of non-verbal sound sequence memory test (p = 0,001), frequency pattern test (p = 0,000), duration pattern test (p = 0,000) and SSW test in Portuguese (p = 0,006) were observed between SG and CG. CONCLUSION:adolescents exposed to metallic mercury presented a lower performance on most of the auditory processing tests when compared to those who had no history of exposure to mercury. The main deficit found in the study was related to difficulty in distinguishing successive brief sounds.

BACKGROUND: speech perception of elderly, in silence and in the presence of background noise. AIM: to characterize and compare the hearing abilities of elderly in a monaural speech perception test, in the presence and absence of background noise (Speech Discrimination Test - SDT and Speech Perception in Noise - SPIN). METHOD: Participants of this study were 55 subjects of both genders, 60 years old or above, distributed in two groups: Control Group (CG), constituted by elders with no hearing loss and Study Group (SG), constituted by elders with symmetrical sensorineural hearing loss. The SPIN test was used, initially with the presentation of a word list in silence and later in the presence of Speech Noise. RESULTS: no difference was observed between genders in the SDT and the SPIN test. Correlation with age was observed only in the SDT for SG. A significant difference was observed when comparing the performance of the groups in the SDT and SPIN test. Regarding the presence of substitutions in the articulation of words, it was observed that it occurred in both groups and was more frequent in SPIN test, especially for the SG. CONCLUSION: the presence of the noise during the production of speech sounds is disadvantageous for elders, independently of the presence of hearing loss, but having a higher impact for those with hearing loss problems.

(CEFAC Saúde e Educação, 2013-12-01) Cruz, Ana Carolina Almendra; Andrade, Adriana Neves de [UNIFESP]; Gil, Daniela [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
PURPOSE: to compare the performance of adults with auditory processing disorder in behavioral tests before and after formal auditory training, in order to verify the effectiveness of this approach. METHODS: this is a quantitative retrospective study for which we selected 18 individuals with auditory processing disorders evidenced by the behavioral assessment, aged between 16 and 38 years old. All subjects underwent a formal auditory training program conducted in eight sessions of 45 minutes each, twice a week. Sessions were organized in ascending order of complexity of the listening skills srech as, auditory closure, figure-ground for sentences, words, syllables and sounds and nonverbal temporal processing of sounds (analysis of the intensity, duration and frequency). For statistical purposes the results of the SSW test SSI (ICM) and Duration and frequency pattern recognitive obtained before and after auditory training, considering the ear and sex variables. RESULTS: there were no statistically significant differences between the right and left ears. Both men and women when analyzed separately showed better results in post-training. These differences were statistically significant in for duration and frequency pattern tests, for men and women. In SSW improvement in male and SSI R / S -15 females, respectively. In addition, all subjects reported better attention and better communicative performance after auditory training. CONCLUSION: the formal auditory training improves listening skills figure - ground for verbal sounds and temporal processing measured by behavioral tests in adults diagnosed with auditory processing disorders.

(Universidade Federal de São Paulo (UNIFESP), 2019-06-18) Viacelli, Sandra Nunes Alves [UNIFESP]; Pereira, Liliane Desgualdo [UNIFESP]; http://lattes.cnpq.br/0546134611213515; http://lattes.cnpq.br/4417137094868095; Universidade Federal de São Paulo (UNIFESP)
To verify the efficacy of an Intervention Program with three types of stimulation, performed in isolated and combined ways: NeuroAudiotive Stimulation (SENA); Visuomotor Stimulation; and, Acoustically Controlled Auditory Training (TAAC), in students‟ central auditory function and visual perception. Methods. Thirty students from 8 to 11 years old participated (15 boys). Children with normal auditory thresholds and difficulties in school learning were included, among those attended at the speech and language clinic of the institution. Children who were not willing to participate of the study, with evidence of neuropsychiatric disorders, altered auditory processing in one behavioral test only and normal visual perception during screening were excluded. The procedures were: evaluation of auditory processing (resolution and temporal ordering skills, figure-background in monotonic and dichotic listening and a questionnaire answered by parents about auditory behaviors in daily communication); SAB scale; visual perception evaluation (DTVP 2); and, evaluation of short evoked potential (FFR) and long latency (p300). The first evaluation performed was called time 1. After the first type of stimulation, the reevaluation was performed (time 2). After the program ended, last evaluation were performed (time 3). Children were submitted to a intervention program, with three different types of stimulation (seven and a half hours each): SENA, TAAC and VISUOMOTOR, presented in different sequences. First sequence was named GROUP 1 (SENA, VISOMOTOR, TAAC), the second one GROUP 2 (VISOMOTOR, SENA, and TAAC) and the third one, GROUP 3 (TAAC, SENA, and VISOMOTOR). Among the stimulations, two of them offered auditory stimulation, ie, TAAC and SENA, and the remaining one, visuomotor (placebo). TAAC was performed as used in clinical practice. SENA consisted of intermittent speech and music auditory stimulation, provided by headphones to the child while performing a motor activity through computer games. An analog converter was used, which allowed SENA application in three children at the same time. Visuomotor stimulation consisted of spatial orientation, balance, segmental limb awareness and visuomotor coordination activities, in groups of five children. Participants were distributed by convenience into each intervention group. The intervention groups age distribution was carefully xvi structured, being three children of 8 years, three children of 9 years, two of 10 years and two of 11 years of age, totalizing 10 participants per group. Results. A longitudinal analysis to verify the intervention program effectiveness showed a statistically significant difference between the three moments, for 95% of the analyzed variables. In a cross-sectional analysis to verify performance between groups at each time point, it was observed that at time 1 there were no statistically significant differences. At time 2 there was a statistically significant difference in E-wave latency in FFR and TPD in imitation and naming tasks for group 3, indicating effect of the intervention sequence that began with acoustically controlled auditory training. In addition, in SAB total score, we verified a statistically significant difference in performance for group 1, indicating the effect of intervention sequence that began with SENA. At time 3, statistical significance occurred for p3 latency in right and left ear in group 3, indicating effect of intervention sequence that began with acoustically controlled auditory training. Also in time 3, the improvement in TDD in group 1 left ear indicating effect of intervention sequence that began with SENA. Conclusion. There was efficacy of the therapeutic procedures used in the research. The best treatment options were group 1 (started by SENA) or group 3 (started by TAAC). The sequence should be defined by the diagnostic evaluation before the therapeutic course. We emphasize the results of this study should be interpreted in a partial way, since the sample does not allow generalizations, requiring additional research to better understand the findings for SENA.

A habilidade temporal e o reconhecimento de fala competitiva em usuários de implante coclear
(Universidade Federal de São Paulo (UNIFESP), 2020-03-05) Salvato, Carolina De Campos [UNIFESP]; Chiari, Brasilia Maria [UNIFESP]; http://lattes.cnpq.br/3118172851522969; http://lattes.cnpq.br/2465568273406624; Universidade Federal de São Paulo
Introduction: Hearing impairment (AD) can harm the subject in several contexts, which often generates negative feelings and difficulties in communication. To mitigate the commitments generated by AD, there are compensatory conducts, among them, the Cochlear Implant (CI). Although this device contributes to hearing improvement, many users still have several complaints of speech recognition in a noisy situation (competitive speech). Thus, factors other than audibility, can act in this recognition, among them the temporal ability. Objective: To verify if there is a correlation between the performance of temporal processing and the recognition of competitive and / or distorted speech in patients using Cochlear Implants. Method: Participants underwent the following assessments: anamnesis, free field audiometry with Cochlear Implant at 250 to 4000Hz sound frequencies, TPF - “Frequency Pattern Test”, TPD - “Duration Pattern Test”, SSI - Test of Sentencing Identification with Competitive Message (Synthetic Sentences Identification in Portuguese) and LSP - "List of Sentences in Portuguese" in the noise condition. The data were analyzed using the Pearson and Spearman coefficient, the Shapiro-Wilk test, the Mann-Whitney U test, the Student t test and two-dimensional scatter plots. In addition, a descriptive analysis of the data was performed using the SPSS Statistics software, version 25.0. Hypothesis: CI users with greater difficulty in temporal ability are those who have the worst performance in competitive speech. Results: There was a statistically significant relationship between the tests that assess temporal ability - SSI and TPF (appointment) - and the test that evaluates competitive speech recognition - LSP. Conclusion: CI users who performed well in the test with competitive speech in the noise condition (LSP) obtained equivalent results in the SSI tests (signal-to-noise ratio +10, 0, -10), and TPF - appointment, which assess the ability of deep figure and temporal ability, respectively.

Identificação de sentenças sintéticas (SSI) e reflexo acústico contralateral
(Pró-Fono Produtos Especializados para Fonoaudiologia Ltda., 2005-12-01) Anastasio, Adriana Ribeiro Tavares; Momensohn-santos, Teresa Maria [UNIFESP]; Pontifícia Universidade Católica de São Paulo; Universidade de São Paulo (USP); Universidade Federal de São Paulo (UNIFESP); PUC-SP Departamento de Clínica Fonoaudiológica
BACKGROUND: the study of the relationship of the contralateral acoustic reflex with the auditory skill of closure. AIM: to analyze the identification of a speech signal in the presence of competitive sounds in subjects with absence of contralateral acoustic reflex. METHOD: application of the synthetic sentence identification (SSI) test under the conditions of competitive contralateral message (SSI-CCM), with the signal-to-noise ratio of 0 and -40dB, and ipsilateral competitive message (SSI-ICM), with the signal-to-noise ratio of 0, -10, -15 and -20dB, in 43 young adults (group A = 21 subjects with contralateral acoustic reflex present in all of the investigated frequencies, and group B = 22 subjects with contralateral reflex absent at the frequency of 500Hz, or in all of the investigated frequencies, or still in some of the investigated frequencies necessarily including 500Hz), of both gender, with no hearing, otologic or learning disabilities. RESULTS: the acoustic reflex threshold was above 100dB NA in 59% of the individuals in group B and in 14% of the individuals in group A. All subjects performed according to the normal pattern suggested in the specialized literature for the SSI test. The performance of group B in the SSI-ICM test was inferior to that of group A for all the signal-to-noise ratios used, although the difference was not statistically significant. Group B, which presented an acoustic reflex threshold higher than 100dB NA or the absence of the acoustic reflex, was also the group that presented the worse performance in the SSI test. CONCLUSION: the absence of the contralateral acoustic reflex seems to interfere in the identification of the speech signal in the presence of competitive noises.

Ordenação e resolução temporal em cantores profissionais e amadores afinados e desafinados
(Pró-Fono Produtos Especializados para Fonoaudiologia Ltda., 2006-12-01) Ishii, Cintia [UNIFESP]; Arashiro, Priscila Midori [UNIFESP]; Pereira, Liliane Desgualdo [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
BACKGROUND: temporal ordering and temporal resolution. AIM: to compare the performance of professional singers with that of well tuned and out of tune amateur singers in the pitch pattern test (PPT) and in the Random Gap Detection Test (RGDT). METHOD: participants were 78 individuals, male and female, with ages ranging from 18 to 55 years. All of the participants were singers with normal hearing - previously assessed using pure tone and speech audiometry - and had no language, speech, voice or hearing complaints. Each individual answered a questionnaire concerning, among other subjects, perception about own voice when singing, number of years of professional singing, difficulties when singing new songs and number of years of music study. For the objective assessment the PPT and the RGDT were used in order to investigate temporal ordering and temporal resolution respectively. RESULTS: regarding the RGDT, there was no statistically significant difference between the groups and variables. As for the PPT, it was observed that professional singers presented a better performance, with statistic significance, when compared to well tuned amateur singers and these a better performance when compared to out of tune amateur singers. The performance in the PPT was related to specialized training and study of music theory. CONCLUSION: the RGDT did not prove to be a sensitive test to distinguish professional and amateur singers. On the other hand, the PPT did. The performance in the PPT reflects the number of years of specialized auditory training and music theory study.

Percepção Espacial / Visuomotora Associada Ao Processamento Auditivo Em Crianças Na Fase Escolar: Intervenção E Reedução
(Universidade Federal de São Paulo (UNIFESP), 2017-09-04) Goncalves, Fatima Aparecida [UNIFESP]; Pereira, Liliane Desgualdo [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
Abstract: The discrepancy in temporal and spatial/motor orientation is pointed out in the literature as co-occurring in learning disorder cases. However, educational and therapeutical practices focus temporal stimulation, which is directly linked to language mechanisms, whereas despite acknowledged as associated, spatial/motor orientation is not emphasized. Researches show that both plasticity and maturation of sensory and perceptual systems are affected by stimulation, once stimulus and experience activate and reinforce specific neural pathways. This study brings a multisensory therapeutical/educational intervention group approach, held inside the school to improve auditory perceptual capacity and spatial and motor organization of the school age child as well as social interaction in small groups. Objective: this paper aims to verify the efficacyduto of an intervention program involving spatial/motor and auditory intervention in children from ages 9 to 11, with no cognitive alterations. Method: 162 children from public schools, from both genders, considered cognitively adequate according to Raven Progressive Matrix (1992) were divided into four groups: three experimental groups: multisensory group; auditory/motor group; and motor/auditory group - which received stimulation sessions; and a control group without stimulation. All groups were evaluated by means of Motor Development Scale; Simplified Evaluation of Central Auditory Processing; Visuospatial Test from Luria/Nebraska Neuropsychological Battery and Scale of auditory behaviors (SAB). The experimental groups were evaluated and re-evaluated after eight weeks without intervention. They then received different types of intervention involving auditory and spatial/motor aspects combined and isolated. They were re-evaluated after eight stimulation sessions (4 weeks) so that the groups of isolated stimulation could change the stimulated aspect and once more, after eight more stimulation sessions (4 more weeks). The control group was evaluated in the beginning of the program and re-evaluated after 16 weeks. Results: in the experimental groups, there was significant effect (p < 0,01) in comparison between instants with and without intervention in relation to variables which were: balance, spatial organization, temporal organization and transition of time structures (dictation) on the motor scale; verbal and nonverbal sequential memory; and for the score referring to the auditory, attention, and total score in SAB. There was no statistical significance in the variables of the visuospatial test. There was also a significant effect in the comparison between intervention groups on the following variables: temporal organization (p<0,01) and score referring to the attention aspect and total score in SAB scale (p<0,02). Conclusion: The three experimental groups benefited from the intervention, especially after the first eight sessions of stimulation (4 hours training), with more significance to the groups of isolated stimulation, auditory/motor and motor/auditory. The experimental groups differed statistically from the control group on most studied aspects.

Processamento temporal em idosos: o efeito da habilidade de resolução temporal em tarefas de ordenação de série de sons
(CEFAC Saúde e Educação, 2013-10-01) Mesquita, Loriane Gratão De [UNIFESP]; Pereira, Liliane Desgualdo [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
PURPOSE: to determine the effect on the ability of temporal resolution in the temporal ordering of a series of sounds with time of stimulation and varied interval inter-stimulus in an elderly population with or without hearing loss. METHOD: 10 (ten) elderly individuals with hearing loss from mild to moderate, who did or did not use hearing aids and 5 (five) subjects without hearing loss, aged from 60 to 80 years old, were tested for temporal ordering of series of sounds with pure tone, named standard pattern of Duraction, and musical tone, named standard test for melodic duration and temporal resolution Gaps-in-Noise test or GIN test. RESULTS: in the analysis of the test of temporal resolution as the percentage of correct identification, it was found that the group with no hearing loss has a higher percentage of identification of gaps than the group with hearing loss. Thus, individuals with hearing loss had worse threshold detection gaps (average of 1.4 milliseconds) than individuals without hearing loss (4.6 milliseconds). In the analysis of each test of ordering series of sounds, there were no statistically significant differences between groups. There was no significant correlation between the performance of the elderly with and without hearing loss among the temporal processing tests. CONCLUSION: the ability of temporal resolution does not affect the ability of temporal ordering of a series of sounds with duration of stimulation and varied inter-stimulus intervals in the elderly with or without hearing loss.

Purpose the aim of this study was to attempt to correlate data from auditory processing with the data collected during the interview of children and teenagers. Method we analyzed the information from medical records of 51 patients of both genders, ages 5 to 20 years, assisted at the auditory processing evaluation service, UNIFESP. The features observed in the interview were: learning difficulties, presence of depression / motivation, use of medication, need for psychological treatment or pedagogical, and problems with attention and memory. Results we found 86% of cases with learning difficulties, 43% were receiving psychological treatment or pedagogical, 37% had problems with attention and memory, and 33% were using medication. None of these symptoms, however, could be associated with changes in temporal processing (ordinance and resolution) and recognition of non-verbal sounds in dichotic task (selective attention). Conclusion it is necessary to produce new studies to discuss the emotional and social issues received during the interview that possibly are related to auditory processing disorders and learning difficulties.

Resolução temporal auditiva na migrânea menstrual
(CEFAC Saúde e Educação, 2014-06-01) Cibian, Aline Priscila; Pereira, Liliane Desgualdo [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
Purposeto verify auditory behavior of temporal resolution in women with Menstrual Migraine. Method40 women had participated, age between 18 to 31 years, 20 of them had presented menstrual migraine (study group) and 20 had not (control group). All of them were submitted to procedures which are part of an audiology’s routine. These procedures were made to characterize the peripheral hearing and to exclude people with hearing loss. They were also requested to answer a questionnaire elaborated for the researcher and submitted to the test Gap in noise. These procedures were carried out both in the precocious follicular phase and in the delayed luteal phase for volunteers who did not use any type of contraceptive, because in these periods the levels of the female hormones are higher and similar to those that used contraceptive. Resultin the group of study, the values for the threshold gap and the percentage of rightness, regarding to the left ear were significant and statistically different relative to the control group. Within the right ear, the results were similar considering the two groups. Conclusionthe temporal resolution in women with menstrual migraine, measure in a specific noise segment, regarding to the right ear, was similar for women without this complain, while in the left ear, the average of thresholds gap were different and those with migraine had the worst thresholds.

BACKGROUND: speech comprehension difficulty is a very common complaint of individuals with tinnitus with and without hearing loss. This study was conducted in order to analyze if tinnitus interferes in auditory processing and speech comprehension in individuals with normal hearing levels. AIM: to asses and compare the auditory behavior of temporal resolution and selective attention of adults with normal hearing levels with and without tinnitus. METHOD: 45 individuals, 15 with continuous tinnitus and 30 without tinnitus were selected and assessed by three auditory processing tests: Speech in Noise Test, Dichotic Digits Test and Gaps in Noise. After that, the results of each group were compared by appropriated statistic's tests; one of them was ANOVA. RESULTS: there were no significant statistical differences between the groups and both ears. CONCLUSION: tinnitus did not interfere in the auditory abilities of selective attention and temporal resolution.

Introdução: Com o processo de envelhecimento observam-se modificações estruturais e fisiológicas diversas em todo o corpo humano. O processamento temporal declina com o aumento da idade, independente da presença ou não de perda auditiva. Habilidades do processamento temporal são a base do processamento auditivo,podendo influenciar diretamente na qualidade da comunicação. Objetivo Geral: Investigar o efeito do processo de envelhecimento no comportamento auditivo de resolução temporal. Método: Participaram do estudo 16 pessoas de faixa etária média de 67,8 anos e média de 7 anos de escolaridade, com audiometria dentro dos valores de normalidade até 4KHz e timpanometria com curva tipo A bilateralmente. Foram realizados os testes Gap In Noise (GIN), anamnese, medida de independência funcional (MIF), escala de depressão geriátrica (GDS), mini exame do estado mental(MEEM), teste ADAS-COG, avaliação audiológica básica, teste dicótico de digitos(TDD) e teste padrão de duração (TPD). Resultados: Todos os idosos disseram "escutar bem", entretanto, 68,8% dos idosos tiveram queixa de "dificuldade de comunicação em ambientes ruidosos". Os idosos tiveram um bom desempenho no IPRF na orelha direita (90% de acertos) e esquerda(91% de acertos). No TDD, a média de acertos manteve-se acima de 88% para a orelha direita(95%) e esquerda (89,8%). A média de acertos no TPD foi de 68,5%. A pontuação média na MIF foi de 121,3 pontos, na escala de depressão geriátrica(GDS), 4,5 pontos (dp=3,5) e no Mini Exame do Estado Mental (MEEM), 26,6 pontos (dp=2,3). Os valores médios observados do limiar de detecção de gap (Teste GIN) foram 10,2 ms na orelha direita e 9,1ms na orelha esquerda. Houve uma tendência em diminuir o limiar de detecção de gap no teste GIN com a melhora da capacidade funcional, avaliada através da MIF.Houve também uma tendência de queda do limiar de detecção de gap com o aumento do MEEM na orelha direita. Não houve correlação entre os limiares de detecção de gap e a porcentagem de acertos no IPRF. Observou-se uma tendência de queda do limiar na orelha direita com o aumento da porcentagem de acertos nos testes dicótico de dígitos e padrão de duração. Há correlação entre o limiar de detecção de gap na orelha direita e a pontuação geral no ADAS-COG. Conclusão: O processo de envelhecimento influencia no comportamento auditivo de resolução temporal.
