Abstract

LA PRESENTE INVENCION SE REFIERE A UN MATERIAL DE PROTECCION ACUSTICA. ESTE MATERIAL SE CARACTERIZA EN QUE COMPRENDE RESONADORES DISPUESTOS SOBRE UN SUSTRATO (2) CONSTITUIDO POR ELEMENTOS FILIFORMES Y/O DE SUPERFICIE (1) CUYAS CARACTERISTICAS DE ESTRUCTURA (DENSIDAD, MODULO DE ELASTICIDAD, MODULO DE CIZALLADO, FACTOR DE AMORTIGUACION, FACTOR PIEZOELECTRICO, ETC...) ASI COMO LA FORMA Y/0 LAS DIMENSIONES SON ELEGIDAS PARA ASOCIAR A CADA RESONADOR UNA FRECUENCIA DE RESONANCIA PREDETERMINADA, POR UNA PARTE, Y POR OTRA PARTE, ABSORBER A DICHA FRECUENCIA DE RESONANCIA LA ENERGIA DE PRESION ACUSTICA PROCEDENTE DE LA FUENTE DE RUIDO Y DISIPARLA EN FORMA DE ENERGIA MECANICA DE CALOR Y/O DE ENERGIA ELECTRICA.THE PRESENT INVENTION REFERS TO AN ACOUSTIC PROTECTION MATERIAL. THIS MATERIAL IS CHARACTERIZED IN THAT IT INCLUDES RESONATORS DISPOSED ON A SUBSTRATE (2) CONSISTING OF FILIFORM AND / OR SURFACE ELEMENTS (1) WHOSE CHARACTERISTIC FEATURES OF STRUCTURE (DENSITY, ELASTICITY MODULE, FACTOR OF EFFICIENCY, FACTOR OF EARTH ...) AS WELL AS THE FORM AND / OR DIMENSIONS ARE CHOSEN TO ASSOCIATE EACH RESONATOR WITH A PRE-DETERMINED RESONANCE FREQUENCY, ON THE ONE PART, AND ON THE OTHER PART, ABSORB SUCH RESONANCE FREQUENCY FROM THE SOUND PRESSURE ENERGY FROM THE SOURCE OF NOISE AND DISSIPATE IT IN THE FORM OF MECHANICAL HEAT ENERGY AND / OR ELECTRICAL ENERGY.
