TORONTO SUBWAY NOISE MEASUREMENTS
Thousands of commuters take the Toronto subway every day, but they may be exposed to damaging levels of noise on their route to work. This data visualization shows the peak levels of noise along the four Toronto subway lines. At 115 decibels, damage to hearing can occur within half a minute of exposure. Even at 100 decibels, your hearing is at risk after only 10 minutes of exposure . This graph, intended for presentations and journal publication, was designed to invoke the original Toronto Transit Commission map and highlight Toronto's noisiest stations.
