University of Bath researchers have developed a graphene-based light material that can reduce aircraft engine noise and improve passenger comfort.
The graphene oxide-polyvinyl alcohol aerogel weighs just 2.1kg per cubic meter, making it the lightest sound insulation material ever manufactured. It could be used as insulation within aircraft engines to reduce noise by up to 16 decibels – reducing the 105-decibel roar of a jet engine taking off to a sound closer to that of a hair-dryer.
