Lightest Sound Insulation Ever Created Will Make Aircraft Engines 80% Quieter

Posted by in categories: government, transportation

In aviation, any advancement in design must either reduce weight or the benefit has to be worth the extra weight. Researchers at the University of Bath seem to have achieved the perfect balance between the two by developing a way to reduce aircraft engine noise by up to 80% while adding almost no extra weight.

As Green Car Congress reports, the research team at the University of Bath developed a graphene oxide-polyvinyl alcohol aerogel, which only weighs 2.1kg (4.6lbs) per cubic meter and therefore makes it the lightest sound insulation ever manufactured.

Researchers developed a graphene aerogel that reduces engine noise to the same level as a hair dryer.
