Indian Institute of Technology Researches Eco-Friendly Sound Absorbers From Seaweed

From airplanes to apartments, most spaces are now designed with sound-absorbing materials that help dampen the droning, echoing and murmuring sounds of everyday life. But most of the acoustic materials that can cancel out human voices, traffic and music are made from plastic foams that aren’t easily recycled or degraded. Now, researchers from the Indian Institute of Technology Kanpur have created a biodegradable seaweed-derived film that effectively absorbs sounds in that frequency range.
