Purpose Check the number of vocal symptoms reported by teachers and the relationship with the self-perception of the limitations of daily activities associated to the voice, personal, occupational and clinical aspects. Methods Refers to a study performed by the analysis of secondary data from medical records of teachers attended at the voice ambulatory of a teaching hospital. The informations of interest were: age, number of taught shifts, parallel activities to teaching, fan use, conversational noise, dust, construction noise, external noise, screaming, smoking habit, hydration, pellet use, physical activity associated with speech, type and degree of dysphonia, proprioceptive vocal symptoms and responses to the Protocol of the Profile of Participation and Vocal Activities (PPVA). It was realized a descriptive and inferential analysis. Results Were collected informations of 103 medical records, where it was found high prevalence of vocal symptoms, with the most frequent: fatigue after prolonged use of the voice, dry throat, throat clearing and burning. It was observed an association between the number of vocal symptoms and the scream habit, conversational noise and perception of the impact of dysphonia by teachers. The number of self-reported vocal symptoms was positively correlated with all parameters evaluated by PPVA. Conclusion There is high frequency of proprioceptive vocal symptoms among the teachers. The noise of conversation and scream habit are associated with the number of vocal symptoms, as well as the parameters of self-perception of the impact of dysphonia contained in the PPVA.

Objetivo Avaliar o reconhecimento de fala, considerando a previsibilidade da palavra a partir de um teste elaborado. Metodos Foi realizada anamnese, testes de rastreio de comprometimento cognitivo e depressao e avaliacao audiologica convencional. Foi desenvolvido um Teste de Reconhecimento de Fala utilizando Frases de Previsibilidade Alta e Baixa e aplicado a 36 idosos (G1 e G3 - grupos sem perda auditiva ate 4 kHz e G2 e G4 - grupos com perda auditiva neurossensorial de grau leve a moderado). Dois grupos realizaram o teste no silencio e com ruido (relacao sinal/ruido +5 dB) e os outros dois grupos somente com ruido (relacoes +5 dB e 0 dB). Resultados O teste de reconhecimento de fala revelou, de modo geral, maior pontuacao nas frases de previsibilidade alta e melhores desempenhos para os grupos sem perda auditiva. No silencio, os idosos sem e com perda auditiva obtiveram pontuacao maxima igual e as menores pontuacoes ocorreram na condicao de ruido mais intenso. O beneficio da previsibilidade foi positivo para os grupos 1, 2 e 3. O grupo 4 apresentou comportamento variado quanto ao uso da previsibilidade (ora positivo, ora negativo). Conclusao Com a populacao de idosos avaliados e as diferencas observadas em um dos grupos considerados, nao foi possivel compreender, com exatidao, como os idosos se beneficiam do apoio da previsibilidade. A perda auditiva e a presenca do ruido influenciaram negativamente o desempenho no teste. Faz-se necessaria a continuidade desta linha de pesquisa para determinar a validade do material elaborado.

Objetivo: Caracterizar os valores de reflectância e absorvância de banda larga em lactentes com integridade de orelha media. Metodos: Foram analisados os valores de reflectância e absorvância de banda larga, para os estimulos chirp e tom puro, de 31 orelhas de 18 lactentes, na faixa etaria de 10 dias a cinco meses de idade. Considerou-se como criterios de inclusao: ausencia de fator de risco para deficiencia auditiva, timpanometria com sonda de 1000 Hz, sugerindo normalidade de orelha media e presenca de emissoes otoacusticas evocadas por estimulo transiente, na triagem auditiva neonatal. Resultados: Os valores de reflectância mostraram-se maiores para as baixas frequencias, reduzindo para as medias e aumentando, novamente, para as frequencias altas, enquanto para os valores de absorvância, o comportamento foi o oposto. Nao existiu diferenca significativa entre os estimulos chirp e tom puro. Conclusao: Observou-se um comportamento tipico das medidas estudadas, caracterizado por maior reflectância nas frequencias graves e maior absorvância para as frequencias medias.

Purpose: Investigate the effect of age in stressed vowels identification in Brazilian Portuguese in children. Methods: The hearing-perceptual performance of 155 children, between 5 and 9 years old (divided in 2 groups: G1 and G2) was evaluated with the use of a software named Perception Evaluation Auditive & Visuelle (PERCEVAL), in a task of stressed vowels identification in Brazilian Portuguese. Acoustic and visual stimuli were presented, asking a child to choose the corresponding picture according to the word listened, between two possibilities of images shown on a computer screen. The presentation time of the stimuli and the children's reaction were calculated, automatically, by the software. Results: The group of older children (G2) presented a better hearing-perceptual accuracy, comparing to the accuracy of the younger children's group (G1). As to the reaction time, the G1 has always presented a higher reaction time comparing to the children in G2, for both the mistakes and successes. As to the standard of mistakes, generally, the groups didn't differ. The analysis of correlation between age and accuracy showed that the children from G1 presented a positive correlation with the age. However, it didn't happen with the children from G2. Conclusion: The hearing-perceptual ability, concerning the identification of vocalic contrasts, seems to occur gradually and stabilizes at 9 years old.

Purpose: To identify in the literature the use of psychometry in Speech Therapy, besides the processes used in the search for validity evidence for the instruments in that field. Research strategy: The databases investigated were MEDLINE (accessed via PubMed), LILACS, Scopus, and SciELO. The descriptors used were “Validation studies,” “Validity of tests,” “Speech, Language and Hearing Sciences,” and “Valid” (followed by a truncation element) in Portuguese, English, and Spanish. Selection criteria: The review included studies that performed some type of validation of tests in Speech Therapy. The survey found 296 papers, 48 of which were included. Most studies were published by international journals in Speech Therapy and with broad-age-group samples. Results: The main area assessed by the instruments was language (20 studies), followed by audiology (13 studies). The year with the highest number of publications was 2014 and the main type of search for validity evidence was based on the internal structure. Conclusion: The principles of search for validity evidence are still scarcely used for instruments in Speech Therapy. However, most studies were developed in recent years, which shows the current trend for focusing on the need for enhancing the instruments.

Purpose: This paper presents the methodology and research tools of a self-reported household survey of speech, language, swallowing and hearing (SLS-H) disorders implemented in southern Brazil. Methods: For the conduction of the study itself, a long step of planning and pilot activities was conducted. This included selection and training of field staff, development, test and retest measurement instrument of self- reported SLS-H disorders and approach techniques and completion of the questionnaires have been tested and applied, because of the complexity of the study. Results: The average time of interview varied from 35 to 15 minutes depending of interviewers experience and for both groups after some fieldwork the average time spent declined. The occurrence of “do not know or didn't inform” answer ranged from 0.2% (95% CI 0.0;1.6) and 6.1% (95% CI 2.8;11.3). Its lowest occurrence was for questions relating to the history of hoarseness and tinnitus by proxys. Incidence was higher for the question related to the perception of change in vocal emission associated with aging. Conclusion: Household survey is feasible and relevant to verify the burden of SLS-H disorders in the general population, although it required extensive knowledge of the study, selection and ongoing training of interviewers to increase the chance of participation, and logistics for the analysis and classification of the information collected.
目的:本文介绍了在巴西南部实施的语音、语言、吞咽和听力障碍(SLS-H)自我报告的家庭调查的方法和研究工具。方法:为了研究本身的开展，进行了长时间的规划和试点活动。由于研究的复杂性，包括现场工作人员的选择和培训，自我报告的SLS-H障碍的开发，测试和重新测试测量仪器和方法技术以及完成问卷的测试和应用。结果:根据面试官的经验，平均面试时间从35到15分钟不等，经过一些实地工作后，两组的平均时间都有所下降。回答“不知道或未告知”的发生率从0.2% (95% CI 0.0;1.6)到6.1% (95% CI 2.8;11.3)不等。其发生率最低的是与代理的声音嘶哑和耳鸣病史有关的问题。在与衰老相关的声音发射变化的感知相关的问题中，发病率更高。结论:入户调查对于验证一般人群SLS-H障碍负担是可行和相关的，但它需要广泛的研究知识，对访谈者的选择和持续培训以增加参与的机会，以及对收集到的信息进行分析和分类的后勤工作。

Purpose: Characterize and measure the voice self-perception of patients pre and post speech therapy treatment using the Indice de Desvantagem Vocal (IDV) protocol, adapted from the Voice Handicap Index (VHI) protocol. Methods: This is a cross-sectional study using a database of patients seen in a speech therapy service. Results: The sample comprised 23 patients, 16 (69.6%) of whom female and seven (30.4%) male. The mean age was 58 years and the mean therapy duration was three months with 11 sessions. Among the types of dysphonia found, organic was the most frequent (47.8%) followed by functional (30.7%) and organic-functional (21.7%). The protocol's total score median decreased prior to intervention compared to the post-intervention period, which means a lower voice handicap. Moreover, 80% of the protocol's questions significantly differed when compared pre and post speech therapy. Conclusion: A difference was found in voice perception after speech therapy intervention, indicated by lower scores in the IDV items. The findings show the importance of using the IDV protocol in clinical practice to help the speech therapist target the treatment and understand the voice behavior of dysphonic patients. Further research is suggested given the instrument's efficacy.

Purpose: To establish the audiological profile of agricultural drivers simultaneously exposed to noise and hydrocarbons. Methods: The study comprised analysis of the medical records of agricultural drivers with hearing complaints, from an agricultural company of Lencois Paulista (SP), Brazil, within the Environmental Risk Prevention Program. The information analyzed included age, period of simultaneous exposure to noise and hydrocarbons and testing of reference pure tone audiometry. Survival models for grouped data (proportional risk and logistic) were adjusted to analyze the influence of age and period of exposure of hearing thresholds. Results: It was observed that the effects of age and period of simultaneous exposure to noise and hydrocarbons were significant for hearing loss in proportional risk and logistic models. Conclusion: It is fundamental to develop actions for the prevention of hearing loss in agricultural drivers exposed to the agents noise and hydrocarbons.

Purpose: Systematically review the scientific literature on Middle Latency Response (MLR) in Brazilian children and adolescents. Research strategy: We searched articles published since 2009 in Portuguese, English or Spanish at MEDLINE, SciELO, BIREME and LILACS electronic basis. Selected articles involved the use of MLR in children and / or Brazilian adolescents. After screening process, articles were analyzed according to “Strengthening the Reporting of Observational Studies in Epidemiology” (STROBE) initiative. Selection criteria: Repeated articles (due to database repetition) and case reports were excluded. Results: From 1315 identified articles, eight were selected for the review. It was predominantly observed: cross-sectional studies (75%); click stimulation (100%), with rate up to 11/s (100%) and 70 dBHL intensity (88%); filtering high-pass 10 Hz (50%) and low-pass 200 Hz (75%); electrode array with actives placed at C3/C4, references at A1/A2 and neutral at Fpz (88%); Na-Pa amplitude as main measure of comparison and normality; and the use of ANOVA test (63%) for statistical analyses. The average latency of Pa wave and Na-Pa amplitude in normal-hearing children and adolescents of the studies was 32 milliseconds and 1.57 microvolts respectively. Conclusion: There is no consensus on MLR collection parameters in Brazilian children and adolescents. Still, the Pa latency average and Na-Pa amplitude found in Brazilian normal-hearing children and adolescents evaluated on the eight articles of this review agreed with normative parameters established internationally.

Purpose: To characterize the Long-Latency Auditory Evoked Potentials (LLAEP) (P1, N1, P2, N2, P300) with acoustic stimuli presented in sound field system in children with normal hearing, as well as to verify the stability of these potentials. Methods: This prospective, longitudinal study comprised 17 children with ages between 6 and 13 years and hearing thresholds within normal. The LLAEP P1, N1, P2, N2, P300 were recorded with speech stimuli and tone burst presented in sound field system, in three different moments: initial assessment (M0), three months after the initial assessment (M3), and nine months after the initial assessment (M9). Results: When the speech stimuli was used, there was a decrease in the latency values of components P1 (M0xM3/M0xM9/M0xM3xM9) and P2 (M0xM9), as well as an increase in the amplitude of P300 (M0xM3) over time. With the tone bust stimuli, it was verified a decrease in the latency values of P300 (M0xM9) over time. Conclusion: it was possible to identify the components of the LLAEP in most individuals. The P1, N1, P2, N2 (tone burst) and N1 and N2 (speech) did not change their latencies and amplitudes between the different moments of evaluation, suggesting stability of this potential in the period of 9 months. The P300 was the component most sensitive to the time intervals considered, since it presented modifications over time that indicated maturation of the central auditory nervous system. The latencies of all components obtained with speech stimulus were higher than with tone bursts, indicating that different stimuli generate different cortical responses.
