ETS researcher enhances “affordable product that promotes safety,” according to industry partner
To help overcome the increasing risk of hearing loss suffered by construction workers, EERS, a Quebec-based start-up, is developing technology to address this common industrial worksite complaint.
They’ve developed a “smart” device, called SonX, which is designed to block loud noises while allowing the wearers to clearly hear each other’s speech through the earpiece itself. It uses noise-blocking ear plugs fitted with advanced in-ear microphones. The protective hardware also allows employers to monitor their employees’ safety by automatically collecting environmental and health data such as noise levels and ear exposure times. But despite the leading-edge design, there was still room for improvement.
Through Mitacs’ research fellowship program, EERS teamed up with Rachel Bouserhal, a postdoctoral fellow from École de Technologie Supérieure in Montreal. Using her background in electrical and audio engineering, Rachel developed an algorithm that, when programmed into the earpiece, enhances the sound quality of speech that is projected to the wearer.
“My research will help improve sound levels in the in-ear microphone so that it provides clearer voices for better quality communication,” says Rachel.
“Traditional headsets and microphones pick up a lot of noise and are hard to use with other protective devices. So, our solution was to put everything in one device inside the ear.”
Following the release of SonX, EERS plans to further improve their product by exploring the possibility of using jaw movements such as chewing and speaking to power the ear plugs, thereby increasing the use life of the plugs. They also plan to incorporate a brainwave scanner that could detect what sounds on which the wearer is focused.
“Our goal is to develop an affordable product that promotes safety in the workplace,” says EERS founder and CEO Nick Laperle. “Working with Rachel and other Mitacs interns have given us the opportunity to expand our research, uncover new capabilities, and, hopefully, lower the risk of noise-induced hearing loss around the world.”
