RESUMO Objetivo construir e aplicar um material de apoio para respostas ao teste do índice percentual de reconhecimento de fala em crianças. Método estudo descritivo exploratório. A primeira etapa, elaboração de um material, foi realizada pela avaliação de 31 fonoaudiólogos (juízes), com palavras monossílabas e dissílabas, regulares e frequentes, que pertencem ao vocabulário das crianças e figuras que pudessem representar essas palavras. A segunda etapa constituiu-se da aplicabilidade do material em 30 crianças na faixa etária de 2 a 4 anos e 11 meses, com audição normal. Resultados o material foi constituído por 25 palavras e seis pranchas com seis figuras. As palavras selecionadas pelos fonoaudiólogos tiveram como critério o fonema inicial e figuras reais, coloridas e próximas do cotidiano das crianças. A média de acertos apresentada pelas crianças no índice percentual de reconhecimento de fala com apoio das figuras foi de 93% (± 8% desvio padrão) e sem, de 64% (± 25% desvio padrão). Ao comparar os resultados obtidos com e sem o apoio das figuras, observou-se diferença significativa para 15 das 25 palavras do teste, sendo maior o número de acertos quando se utilizou com apoio de figuras. Na comparação entre os acertos e erros obtidos no teste, utilizando as figuras como apoio, houve diferença significativa apenas para a palavra “cão” (p=0,0079). Conclusão houve concordância entre os juízes em relação às palavras e figuras; a aplicação foi rápida e fácil, possibilitando a avaliação e o monitoramento sistematizado da habilidade de percepção de fala independentemente da capacidade de verbalização da criança.

ABSTRACT Purpose To prepare and apply support material for responses to the Speech Recognition Percentage Index (SRPI) test in children. Methods This is a descriptive, exploratory study conducted in two phases: in the first phase, 31 speech-language pathologists (referees) prepared material composed of regular, frequently used monosyllabic and disyllabic words belonging to the vocabulary of children and figures that could represent these words; the second phase consisted in the application of this material to 30 normal-hearing children aged 2 to 4 years and 11 months. Results The material consisted of 25 words and six boards with six figures each. The word selection criterion adopted by the referees included the initial phoneme and real, colorful figures familiar to the children. The mean scores of the children in the SRPI test were 93% (SD ± 8%) with the support of figures and 64% (SD ± 25%) without figure support. Comparison between the results obtained with and without the support of figures showed significant difference for 15 of the 25 test words, with higher scores with the use of supporting figures. Comparison between correct and incorrect responses using the support of figures showed significant difference only for the word “dog” (“cão”) (p=0.0079). Conclusion There was agreement among the referees with respect to the words and figures. The SRPI test can be rapidly and easily applied, allowing evaluation and systematic monitoring of speech perception ability regardless of child verbalization capacity.

Introduction: The effects of lead on children's health have been widely studied. AIM: To analyze the correlation between the long latency auditory evoked potential N2 and cognitive P3 with the level of lead poisoning in Brazilian children. METHODS: This retrospective study evaluated 20 children ranging in age from 7 to 14 years at the time of audiological and electrophysiological evaluations. We performed periodic surveys of the lead concentration in the blood and basic audiological evaluations. Furthermore, we studied the auditory evoked potential long latency N2 and cognitive P3 by analyzing the absolute latency of the N2 and P3 potentials and the P3 amplitude recorded at Cz. At the time of audiological and electrophysiological evaluations, the average concentration of lead in the blood was less than 10 ug/dL. RESULTS: In conventional audiologic evaluations, all children had hearing thresholds below 20 dBHL for the frequencies tested and normal tympanometry findings; the auditory evoked potential long latency N2 and cognitive P3 were present in 95% of children. No significant correlations were found between the blood lead concentration and latency (p = 0.821) or amplitude (p = 0.411) of the P3 potential. However, the latency of the N2 potential increased with the concentration of lead in the blood, with a significant correlation (p = 0.030). CONCLUSION: Among Brazilian children with low lead exposure, a significant correlation was found between blood lead levels and the average latency of the auditory evoked potential long latency N2; however, a significant correlation was not observed for the amplitude and latency of the cognitive potential P3.

OBJETIVO: avaliar as medidas repetidas da resposta de ressonância da orelha externa sem (REUR) e com uso de amplificação (REAR) e o ganho de inserção (REIG), realizados face a face e via teleconsulta. MÉTODO: estudo prospectivo longitudinal. Foram realizadas quatro repetições da REUR, REAR e REIG (com estímulo speech noise apresentado em 65 dB NPS e 0º azimute) em 19 orelhas de adultos ouvintes normais, via face a face (F) e teleconsulta síncrona por controle remoto de aplicativo (T) e vídeo interativo. O software Polycom PVX foi utilizado para compartilhamento e transmissão de áudio e vídeo. A conexão foi realizada via LAN (Local Area Network) USP na velocidade de 384 kbps Foi calculado o erro causal (Dalhberg) entre as quatro medidas para frequências de 250 a 8000 Hz. RESULTADOS: os erros casuais entre as medidas F e T foram muito semelhantes, sendo maiores nas frequências acima de 4 kHz. As diferenças e variações entre as medidas F e T estavam dentro da magnitude de variabilidade do procedimento de medidas com microfone sonda. CONCLUSÃO: as medidas com microfone sonda via teleconsulta fornece resultados confiáveis e similares aos obtidos pelo procedimento padrão.

PURPOSE: to evaluate the repeated measurements of the real ear unaided response (REUR), real ear aided response (REAR) and insertion gain (REIG) conducted as face to face (F) and via telecounselling (T). METHOD: longitudinal prospective study. Four measures of REUR, REAR and REIG (carried out with speech noise stimulus presented at 65 dB SPL at 0° azimuth) were obtained in 19 ears in normal hearing adults, face to face and via synchronous telecounsellings with remote control of the real ear equipment and interactive video. Polycom PVX software was used for desktop sharing and video and audio transmission. The Loca Area Network (LAN) USP was used for the connection (transmission rate: 384 kbps). Dahlberg’s casual errors were calculated for obtaining the measures for frequencies from 250 to 8000 Hz. RESULTS: casual errors between F and T measures were very similar, being greater for frequencies above 4 kHz. The differences between F and T measures were no greater than the variability reported for real ear measures. CONCLUSION: probe microphone measures obtained via telecounselling provides reliable results and similar to those obtained by standard procedures.
