As part of a Workers’ Memorial Week activity, you can join the Occupational Health Clinics for Ontario Workers (OHCOW) in paying attention to noise on the job. On International Noise Awareness Day, they’re crowdsourcing workplace noise measurements on Wednesday, April 26.
To contribute, use their links to the better apps for Android and iPhone. And keep using them once you discover how easy they can be. For more info, see http://www.ohcow.on.ca/avoidnoise/.
