With nearly seven million passengers moving through Port Columbus International airport every year, the jarring sound of airplane noise may be painfully familiar. NASA expects U.S. air traffic to double or triple by 2025, a projection that has engineers working hard to silence the roar. Engineers at Ohio State University have applied for a patent on technology called plasma actuators that could reduce jet noise.
