Abstract
Patente de Invenção: "DISPOSITIVOS ACúSTICOS". Processo de reduzir características que ocorrem em freq³ências específicas, tal como em coincidência. Um painel (11) apresenta excitadores (13, 15) dispostos para reduzir a característica. Os excitadores podem ser acionados em fase, embora sejam espaçados entre si por uma distância substancialmente igual à metade do comprimento de onda das ondas de flexão no painel nesta freq³ência específica.Invention Patent: "ACOUSTIC DEVICES". Process of reducing characteristics that occur at specific frequencies, such as coincidence. A panel (11) has exciters (13, 15) arranged to reduce the characteristic. The exciters can be driven in phase, although they are spaced apart by a distance substantially equal to half the wavelength of the bending waves on the panel at this specific frequency.
