Environmental noise and noise in the interiors, is a major concern. Companies, in sectors as varied as car industry, electric household appliances or aeronautics, focus on reduction of sound level of their products. In order to reduce noise, the use of passive acoustic absorbing materials, like foams, glass wools or rock, may represent a solution. Other materials offer absorbing properties because of their reactivity, for example, materials with resonators cavities. In this category, honeycombs type materials are employed more and more frequently, not only because of their rigidity weight ratio particularly interesting from a mechanical point of view, but also because of their acoustic properties, in particular in the nacelles of the engine...
