Aparelhos auditivos biauriculares têm como objetivo a compensação de limitações na audição humana. Consistem em dois dispositivos de amplificação sonora posicionados nas orelhas, que trocam informações entre si, de forma a propiciar maior inteligibilidade e qualidade da fala. Este trabalho tem como objetivo apresentar um novo modelo matemático para a predição de desempenho do processo de redução de ruído quando a taxa de comunicação entre os dois aparelhos é diminuída para economizar energia. O modelo convencional para a quantização é generalizado para incluir também a saturação. Resultados de simulação indicam maior acurácia na capacidade de predição de desempenho.
