Resumen:
Una universidad checa ha desarrollado un material absorbente acústico con membrana nanofibrosa para aplicaciones en acústica de estancias, transporte y control de ruidos. Este material absorbente resuelve los problemas de ruido de un amplio espectro de frecuencias y es más ligero y delgado que otros materiales. La universidad ofrece diferentes tipos de paneles acústicos con membrana nanofibrosa para fines de demostración y evaluación en laboratorio o in situ. Estos paneles tienen un tamaño de 500 x 600 mm, aunque el tamaño final depende de la aplicación, producción y condiciones de manipulación. La membrana resonante se fabrica con una anchura de 500 mm a escala semi-industrial y con una anchura de 1600 mm a escala industrial. La universidad busca socios interesados en continuar con la investigación y desarrollo para establecer un acuerdo de cooperación técnica, así como empresas interesadas en la producción bajo un acuerdo de licencia.

Tittle:
Sound absorbing material with nanofibrous resonant membrane
Summary:
A Czech university has developed a sound absorbing panel with nanofibrous membrane for applications in room acoustic, transportation and noise control. The sound absorbing material solves noise problem of wide frequency spectrum and is lighter and thinner than others. The scientists are looking for partners interested in further research and development based on a technical cooperation agreement and for companies interested in production under a license agreement.
Description:
Sound absorbing material solves noise problem of wide frequency spectrum.

The Czech researchers offer different types of acoustic panels with nanofibrous membrane for demonstration and evaluation in the laboratory and in-situ having size 500 x 600 mm. The final panel size is dependent on application, production and manipulation conditions. The nanofibrous resonant membrane can be made in 500 mm width in a semi-industrial scale and in 1600 mm width in an industrial scale. The nanofibrous layer is produced in the Czech Republic.

The sample contains for example foam of 10 mm thickness with resonant nanofibrous membrane protected by the thin nonwoven of 20-30 g.m-2 basis weight on the face of the sample.

The sample contains for example perforated panel of 1 mm thickness with resonant nanofibrous membrane protected by the thin nonwoven of 20-30 g.m-2 basis weight on the back of the sample.

The installation distance between wall and sample of 1 mm thickness is effective from 10 mm to 50 mm. The distance can be utilized for light or sound source installation.

The researchers expected in the case of a licensing agreement acquiring a license from the interested partner, where the subject of a license will be know-how for manufacturing the resonant nanofibrous membrane.

Additionally, a joint further research and development or adaptation of the material offered for the specific purposes based on a technical cooperation agreement (e.g. also within a suitable European project such as Horizon 2020) is possible.
Advantages and Innovations:
- Sound absorbing material solves noise problem of wide frequency spectrum from 300 to 10 000 Hz.
- The material is lighter and thinner than others. The thickness is in the range of 2-50mm. The basis weight is in the range of 20-3000 g.m-2.
- The nanofibrous resonant membrane can be applied onto the face of almost any sound absorbing material such as foam, fibrous stuff or any compressible material.
- The price of resonant nanofibrous membrane is close to 2 Euros per 1m2, which should be acceptable with regard to value for price ratio.
