New graphene-based aerogel could reduce aircraft engine noise

University of Bath researchers have developed a graphene-based light material that can reduce aircraft engine noise and improve passenger comfort.

Meringue-like material could make aircraft as quiet as a hairdryer image

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.
