Optimización de las características absorbentes de materiales granulares reciclados

Abstract

[ES] En trabajos anteriores se ha mostrado la posibilidad de utilizar la granza de neumáticos usados para conformar materiales acústicos absorbentes con coeficientes y espectros acústicos adaptados al tipo de ruido. En este trabajo se profundiza mas en esta idea mostrando aspectos teóricos y experimentales de materiales bien monodispersos o polidispersos en los que la variación del coeficiente de absorción en función de la frecuencia puede diseñarse según criterios establecidos a priori, dando como resultado final un producto optimizado tanto bajo los aspectos acústicos como físicos para su mejor maniobrabilidad.

[EN] In this article theoretical as experimental aspects about the possibility of optimising the acoustic absorption behaviour of granular materials is shown. The frequency absorption spectra, for mono or polidisperse materials, can be modelled both under well-established criteria. In this way, a final product can be obtained, optimising their acoustic and mechanical aspects.
