Insertion units which are microperforated for use as sound absorbers.

Abstract

[ES]El objeto de la presente patente consiste en el diseño y realización de materiales y dispositivos absorbentes a una onda acústica alternativos a los materiales fibrosos o porosos y con características de absorción acústica análogas o superiores a los materiales microperforados. Los dispositivos incorporan mallas o elementos acústicos similares con luces submilimétricas, pudiéndose insertar de manera sencilla, en las superficies expuestas a la onda sonora. Las características del espectro de absorción resultante dependen del adecuado diseño de los mismos: luz de la malla, número de elementos a insertar para una superficie de área determinada, tamaño de la cavidad posterior (con posibilidad de regulación individual), etc. Los dispositivos presentan excelentes propiedades mecánicas que permiten de forma sencilla su instalación y posterior limpieza sin pérdida de sus características acústicas, lo que les hacen idóneos para los tratamientos acústicos en los que la higiene, limpieza, y/o situaciones extraordinarias de uso son primordiales.

[EN]The invention relates to the design and production of devices and materials which can absorb an acoustic wave, which provide an alternative to fibrous or porous materials and which have similar or better sound absorption properties than microperforated materials. The inventive devices include meshes or similar acoustic elements with submillimetric holes, which can be easily inserted into surfaces that are exposed to the acoustic wave. The characteristics of the resulting absorption spectrum depend on the design of said elements, namely: hole in the mesh, number of elements to be inserted for a determined surface area, size of the rear cavity (with optional individual adjustment), etc. In addition, the devices have excellent mechanical properties which enable easy insertion and cleaning without the loss of acoustic characteristics. In this way, the devices are suitable for acoustical treatments in which hygiene, cleanliness and/or extraordinary usage situations are essential factors.
