Acoustic Fibers (image) Massachusetts Institute of Technology Caption MIT researchers have demonstrated that they can manufacture acoustic fibers with flat surfaces, like those shown here, as well as fibers with circular cross sections. The flat fibers could prove particularly useful in acoustic imaging devices.
