Abstract
Purpose: To study an initial version of a new computer-based program for auditory processing screening of school-age children: “audBility.” Specifically, the study aimed to analyze performance in individual tasks, level of difficulty per age group, administration time and data management and propose adjustments for a final version to be validated in future research, based on the administration of “audBility” on children with good school performance. Methods: Forty-three school-age children with good school performance were selected. The program assesses hearing skills related to sound localization, competitive dichotic listening, binaural integration, auditory figure-ground, auditory closure, temporal resolution and temporal ordering, as well as a self-perception questionnaire answered by the children. Results: The mean score obtained in the questionnaire was 44.75 ± 6.3. Based on the analysis of performance in the individual tasks, improvements were made in the auditory closure and temporal resolution tests and also the research protocol was reduced and defined to adjust to administration time. It was identified a necessity of two separate modules: one for the age groups of 6 to 8 and other for 9 to 12 years, beyond the inclusion of two new versions of the questionnaire that can be answered by teachers and/or parents. Conclusion: The development of audBility is an advance in the area of central auditory processing screening in school-age children. New researches for the validation of audBility are underway, with an increased sample and comparison with the diagnostic battery. The initial results enabled the development of the final version of the protocol to be used in the validation study.

Resumo
Objetivo: estudar a versão inicial de um novo programa online de triagem do processamento auditivo em escolares: “audBility”. A partir da aplicação em crianças com bom desempenho escolar, a pesquisa teve como objetivo específico analisar o desempenho em cada tarefa, nível de dificuldade por faixa etária, tempo de aplicação, gerenciamento dos dados e propor ajustes e melhorias para a versão final, a qual posteriormente deverá ser validada em pesquisas futuras. Método: participaram 43 escolares com idades entre 8 e 11 anos e bom desempenho escolar. O programa avalia as habilidades auditivas de localização sonora, escuta dicótica competitiva (dígitos e dissílabos), integração binaural, figura-fundo, fechamento auditivo, resolução e ordenação temporal, além de um questionário de autopercepção direcionado aos escolares, baseado no instrumento “Scale of Auditory Behaviors.” Resultados: o escore médio obtido no questionário foi de 44,75 ± 6,3 pontos. A partir do desempenho em cada atividade, foram realizadas melhorias no teste de fechamento auditivo e temporais; redução e definição do protocolo de pesquisa para adequar o tempo de aplicação. Observou-se a necessidade de dois módulos, divididos para crianças na faixa etária de 6 a 8 anos e de 9 a 12 anos, e o acréscimo de duas versões do questionário, direcionados para os pais e professores. Conclusão: o desenvolvimento do audBility é um avanço na área do processamento auditivo e triagem escolar. A validação do audBility está sendo realizada com o aumento da amostra e comparação com a bateria diagnóstica. Os resultados iniciais possibilitaram o desenvolvimento da versão final do protocolo a ser utilizado no estudo de validação.
