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.
