Abstract

"FERRAMENTA DE REGISTRO ACúSTICA, E, MéTODO DE REGISTRO". é descrita uma ferramenta acústica que provê forma de onda de fonte programável. Inúmeras vantagens podem ser atingidas a partir da configurabilidade da forma de onda de fonte. Notavelmente, registros de atividades acústicas em múltiplas freqüências podem ser obtidos com uma única passagem. A forma de onda pode ser adaptada à freqüência para maximizar a resposta de formação e adaptada à amplitude para controle de ganho. Em uma forma de realização, a ferramenta acústica compreende: um controlador, um conversor analógico-para-digital (DAC), um transdutor acústico, e um acionador linear. O DAC converte uma forma de onda digital proveniente do controlador em uma forma de onda analógica. O transdutor acústico converte um sinal elétrico em um sinal acústico. O acionador linear recebe a forma de onda analógica a partir do DAC e responsivamente provê o sinal elétrico para o transdutor acústico. O sinal elétrico é proporcional à forma de onda analógica. A ferramenta também pode incluir uma memória para armazenar a forma de onda digital e/ou software para gerar a forma de onda digital.
