When Ramani Ramakrishnan worked on a project for NASA from 2007 - 2011, the stakes were sky high. An aero acoustician, he was part of a team tasked with building the world’s largest reverberation test chamber. The $80 million facility was used to run acoustic fatigue tests on the Orion, the spacecraft designed to carry astronauts to Mars. To ensure components such as heat shields could withstand launch and reentry, his team installed 24 exponential horns up a 52-foot wall in a room full of nitrogen gas—and turned them on full blast. “One hundred and sixty-three decibels,” Ramakrishnan says. “It was the loudest sound ever made by humans.”

While the NASA work was thrilling, he gets just as much satisfaction from solving acoustic challenges here on earth. One of the top noise control specialists in Canada, Ramakrishnan is often called to consult on projects as varied as housing developments near airports to innovations in the burgeoning field of active noise cancellation. It’s work he both enjoys and takes seriously. “Whether it's hearing loss or structural damage, sounds and vibrations can cause major problems,” he says. “Now, as a professor, I’m proud to show the next generation how to solve them.”
