Abstract

trata-se de uma unidade de cálculo para um sistema de som que compreende meios de entrada, um processador e meios de saída. os meios de entrada têm o propósito de receber um fluxo de áudio a ser reproduzido com o uso do sistema de som. os meios de saída têm o propósito de controlar o sistema de som com base em uma primeira e uma segunda pluralidades de sinais de áudio individuais. o processador é configurado para calcular a primeira pluralidade de sinais de áudio de modo que a formação de feixe seja realizada pela matriz e para calcular a segunda pluralidade de sinais de áudio individuais para realizar, com o uso do sistema de som, a supressão direta de som, de modo que o som seja cancelado em uma direção de escuta. ademais, o processador filtra pelo menos a segunda pluralidade com o uso de uma segunda característica de passa-banda que compreende uma segunda porção da faixa de frequência inteira.
