Abstract

"SISTEMA DE PROCESSAMENTO DE SOM APRIMORADO PARA UTILIZAçãO COM RADIADORES DE SOM". Sistema e método de processamento de som compacto para utilizar com uma pluralidade de radiadores de som. Uma microcontroladora aceita uma pluralidade de parâmetros selecionados pelo usuário de equalização de alto-falantes e de equalização de espaço e recebe um sinal de controle de radiochamada de uma interface telefónica. Um misturador analógico combina as entradas do sinal de música e um sinal de radiochamada. o processador de sinal digital gera e filtra o ruído de máscara, e processa o ruído de máscara e a música combinada e os sinais de radiochamada com base em parâmetros selecionáveis pelo usuário para distribuição para os radiadores de som. Um amplificador de áudio modula e amplifica o sinal de saída do processador de sinal digital, e entrega o sinal de saída aos radiadores de som através de um transformador em zonas definidas. Os radiadores de som podem ser radiadores de som de painel plano ou alto-falantes do tipo convencional. o filtro de máscara utilizado com o gerador de ruído de máscara pode ser programado para formatar o ruído aleatório virtual gerado ao diminuir o ruído a uma taxa constante pela faixa de freq³ência da fala humana. A função radiochamada-sobre-música reduz o nível de som da música por uma quantidade prefixada sempre que um sinal de controle de radiochamada é recebido. Uma controladora de fala de volta também é fornecida para permitir ao individuo responder a uma radiochamada utilizando o radiador de som como um microfone.
