## TL;DR

This study shows that acoustically controlled auditory training improves and maintains auditory skills in children with school performance issues for at least three months.

## Contribution

The study demonstrates the long-term effectiveness of acoustically controlled auditory training in children with central auditory processing disorder.

## Key findings

- Children who received ACAT showed improved performance on auditory tests immediately after training.
- Improvements in auditory skills were maintained or increased three months after the intervention.
- The control group showed less improvement compared to the intervention group.

## Abstract

To investigate the effectiveness of acoustically controlled auditory training (ACAT) and the maintenance of auditory skills acquired by children with impaired school performance.

Sample consisting of 20 schoolchildren: Control Group (CG – N=10) and Intervention Group (IG – N=10), aged from 8 to 13 years old, results below expectations in a school performance screening, adequate results in a cognitive screening and diagnosed with central auditory processing disorder (CAPD) after a battery of behavioral tests. The CG did not receive any type of intervention, only evaluation and reevaluation after three months. The IG was assessed immediately after eight ACAT sessions and three months post-intervention. Auditory processing assessment and reassessment data were subjected to statistical analysis (p<0.05).

The sample was considered homogeneous regarding gender, age, education level and academic performance. Regarding CAP assessment data, both groups were homogeneous (excepting the Synthetic Sentence Identification – SSI test). Children from IG improved their performance on the Dichotic Digit, Consonant Vowel, SSI and Frequency Pattern (FPT) tests immediately after the intervention. After three months of ACAT, these values remained the same or increased, except for FPT. In the qualitative analysis, between normal and altered, the IG maintained adequate results after three months of ACAT. In the CG, six children maintained altered results and four reached normality in the reassessment after three months.

ACAT proved to be effective for rehabilitating the auditory skills of children with impaired school performance even three months after the end of the intervention.

Investigar a efetividade do Treinamento Acusticamente Controlado (TAAC) e a manutenção das habilidades auditivas adquiridas por crianças com desempenho escolar prejudicado.

Amostra constituída por 20 escolares: Grupo Controle (GC – N=10) e Grupo Intervenção (GI – N=10), com idade entre 8 e 13 anos, resultados abaixo do esperado em uma triagem de desempenho escolar, resultados adequados em um rastreio cognitivo e diagnosticados com o Transtorno do Processamento Auditivo Central (TPAC) após bateria de testes comportamentais. O GC não recebeu nenhum tipo de intervenção, apenas avaliação e reavaliação após 3 meses. O GI foi avaliado imediatamente após 8 sessões de TAAC e após 3 meses da intervenção. Dados de avaliação de PAC foram submetidos à análise estatística (p<0,05).

A amostra foi considerada homogênea quanto ao sexo, idade, escolaridade, desempenho escolar. Quanto aos dados de avaliação de PAC, ambos os grupos eram homogêneos (com exceção do teste Identificação de Sentenças Sintéticas - SSI). As crianças do GI demonstraram melhora no desempenho dos testes Dicótico de Dígitos, Consoante Vogal, SSI e Padrão de Frequência (TPF) imediatamente após a intervenção. Após 3 meses do TAAC, tais valores se mantiveram ou aumentaram, exceto TPF. Na análise qualitativa, entre normal ou alterado, o GI manteve resultados adequados após 3 meses do TAAC. No GC, seis crianças mantiveram resultados alterados e quatro atingiram a normalidade na reavaliação pós 3 meses.

O TAAC mostrou-se eficaz para a reabilitação das habilidades auditivas de crianças com desempenho escolar prejudicado mesmo após 3 meses do fim da intervenção.
