The Port of Prince Rupert (PPR) Noise Monitoring Program aims to show real time noise levels at active noise stations through the coloured circles on the right-hand corner map. Additional noise stations will be installed and incorporated into this website in the near future. Tapping the coloured circles shows noise measurements taken at the site at various time resolutions including real-time (graph at center left) and hourly, daily, weekly, or monthly periods (graph at bottom).
