Abstract(s)
A perda auditiva pode ocorrer em diferentes etapas do desenvolvimento na vida do ser humano. Nas pessoas com deficiência auditiva, o impacto na comunicação tem repercussão nos campos profissional, social e familiar. Uma alternativa de reabilitação é a adaptação de próteses auditivas. Este estudo teve
como objetivos comparar a eficácia do sistema de processamento de sinal ChannelFreeTM (“livre de canal”) e MultiChannel (“com canais”), descrever, comparar e relacionar o perfil audiológico e os benefícios subjetivos e objetivos obtidos por pessoas com deficiência auditiva neurossensorial. Foram avaliados
30 indivíduos com idades compreendidas entre os 32 e os 79 anos, com perdas auditivas neurossensoriais de grau moderado a severo bilateral e com experiência de uso continuado de próteses auditivas, há mais de dois anos. Os resultados apresentados indicam pontos importantes do perfil audiológico e medidas de autoavaliação da capacidade de comunicação das pessoas com deficiência auditiva com perda auditiva de natureza neurossensorial, bem como diferença significativa na idade dos participantes. Conclui-se, que o benefício do sistema de processamento de sinal ChannelFreeTM em comparação com o sistema de sinal MultiChannel, fornece uma compreensão fonética para amplificação dos sons mais suaves da fala, sem excesso da amplificação nas altas frequências, ajustando a amplificação adequadamente em todas as
frequências, sem degradação do contraste espetral.
Hearing loss can occur at different stages of development in human life. In people with hearing disabilities, its impact on communication has repercussions on professional, social and family areas. This study aims to describe, compare and relate the audiological profile and subjective and objective benefit obtained by people suffering from neurossensorial hearing loss, and also: compare the individual performance of the systems; bring face to face the benefits before and after the systems; analyse the results of the study and, lastly, present its final results. For this purpose, 30 individuals aged between 32 and 79 years, with neurossensorial hearing loss from moderate to severe bilateral, and with experience of continued use of hearing aids for over two years were evaluated. The results presented indicate important aspects of the audiological profile and measures of self-assessment of communication skills of people with hearing loss and neurossensorial hearing loss nature, as well as a significant difference in the age of the participants. We can conclude, therefore, that the benefit of the ChannelFreeTM signal processing compared with the MultiChannel signal system provides a phonetic understanding for amplification of the softest sounds of speech without excessive amplification at high frequencies, properly adjusting the amplification in all frequencies without degradation of the spectral contrast.
