Abstract

"SISTEMA E MéTODO PARA A FORMAçãO DE FEIXES UTILIZANDO UM CONJUNTO DE MICROFONES". A capacidade de se combinar múltiplos sinais de áudio capturados a partir dos microfones de um conjunto de microfones é freq³entemente usada em sistemas de formação de feixes. Tipicamente, a formação de feixes envolve o processamento dos sinais de áudio de saída do conjunto de microfones de tal modo a fazer com que o conjunto de microfones atue como um microfone altamente direcional. Em outras palavras, a formação de feixes provê um 'feixe de escuta' que aponta para uma fonte sonora em particular enquanto com freq³ência filtra outros sons. Um 'formador de feixes genérico', conforme descrito no presente documento automaticamente desenha um conjunto de feixes (isto é, uma formação de feixes) que cobrem uma faixa de espaço angular desejada dentro de uma área de pesquisa predeterminada. O desenho de feixe é uma função da geometria e das características operacionais do microfone, e também dos modelos de ruido do ambiente em torno do conjunto de microfones. Uma vantagem do formador de feixes genérico é que o mesmo é aplicável à qualquer geometria de conjunto de microfones e tipo de microfone.
