New material developed by MIT researchers able to block out sound entirely
A fiber made up of silk and other common materials has the potential to block out sound entirely — not just amplify it.
Researchers at the Massachusetts Institute of Technology stumbled onto what one called a “very radical” discovery — the new material they had created, akin to silk, could function much in the way a wall does, only at a fraction of the thickness. Yoel Fink, a professor of Materials Science and Engineering at MIT told MassLive fibers are “ubiquitous” in human life, and have been for centuries. The sound-suppression work published recently in the journal “ Advanced Materials ” builds on initial efforts by the same group of researchers to create what Fink described as a hyper-sensitive microphone.
