Intelligent materials for reducing noise


Development Opportunity, Licensing Opportunity

Researchers in the EU programme Intelligent Materials for Active Noise Reduction (InMAR), demonstrated examples of intelligent materials developed to reduce noise and vibration in products such as cars and trains in an exhibition in Darmstadt, Germany last week.

Inmar was a Euro 27 million, four-year research and development project involving 41 partners from 13 countries, and was coordinated by the Fraunhofer LBF in Darmstadt.

In total Inmar included 23 projects. On display was a gearbox mounting of a car which actively reduces vibration transmission in the body; a compressor for an air conditioning system, in which oscillations are reduced with an active vibration absorber; and a sound-proofed window for blocking low frequency sounds such as aircraft noise, or the bass sound from discos.
