World NM: Graphene-based, meringue-like material dampens airplane engine noise001328

Researchers at the University of Bath, in Britain, have developed a new graphene-based material that significantly reduces aircraft engine noise.
When scientists tested the new aerogel material’s sound absorption abilities, they successfully reduced the roar of an airplane engine by 16 decibels, making a jumbo jet sound more like a hair dryer.
The team plans to test the panels in cars and helicopters, as well as airplanes.
