Abstract

"DISPOSITIVO DE COMUNICAçãO COM EQUALIZAçãO ATIVA E MéTODO PARA O MESMO". Dispositivo de comunicação (10, 110) que inclui um dispositivo auditivo (14), um sensor (20) e um circuito de equalização ativa (22). O dispositivo auditivo (14) transmite um sinal de saída acústico (59) do dispositivo de comunicação (10, 110). O sensor (20) está localizado proximamente ao dispositivo auditivo (14) e mede uma pressão acústica (61) no dispositivo auditivo (14) e gera um sinal de resposta (56). O circuito de equalização ativa (22) é acoplado ao sensor (20) e equaliza o sinal de saída acústica (59) utilizando o sinal de resposta (56).
