As many as 22 million workers are exposed to hazardous noise every day at work. To combat that significant occupational health and safety challenge, OSHA, MSHA and NIOSH developed the “Hear and Now” Noise Safety Challenge. Open to the entrepreneur community, the challenge offered 10 inventors, selected from 28 challenge submissions, the opportunity to travel from all over the United States and Canada to present their solutions to better protect workers from hazardous noise.
