Noise

Here is a link to the industry report on projected noise levels for the McLeans Mountain project.
Remember:

• this is just a computer model and computer modelling is notoriously inaccurate (up to 19 dB out)
• only dBA sound is modelled whereas many experts now feel low frequency noise is just as important if not more so
• the accuracy of the predictions are further degraded in hilly territory
• the predictions are based on wind speeds of only 6m/s (20km/hr)
• night noise over 40dBA has been shown to produce serious health effects in a significant number of people
