2 x 55 = 58 PDF Print E-mail

The peculiar maths in the title illustrates the fact that if noise pollution is doubled from a decibel reading of 55 dba, the new decibel reading will only be 58 dba. The math also reveals that incremental changes of 10 dba from 40 to 50 to 60 to 70 dba represent 10- , 100-, and 1,000-fold increases in noise pollution. When noise pollution begins to exceed 50-55 dba, the effects are disturbing, unpleasant und unhealthy - such is already the case in the daytime for many homes in Lions Bay. At nighttime, to avoid the serious effects of sleep disturbance, a level of 40-45 dba is considered as a maximum by many international authorities. Again, nighttime disturbances in Lions Bay are common. The matter is likely to get worse as traffic volumes on the sea-to-Sky Highway increase in the future. Fortunately the Ministry of Transport (MoT) recognizes the problem, and will be attempting to provide various measures to mitigate the potential increases in noise pollution, within its overall mandate of safety and reliability.
