I read in the Tribune that 30 conifers were to be planted in Glinton between the bypass and the end of Helpston Road as a noise barrier. Unfortunately, it is a common misconception that a row of conifers will reduce noise.
It will require a depth of at least 30 metres of dense planting to have a significant effect on noise. Traffic noise will pass straight through a single row of conifers as if they were not there. However, there is the old saying, ‘If you can’t see it you can’t hear it’, and, it is often the case that people perceive a noise reduction when conifers have been planted. I would agree that the conifers should be planted but the nearby residents should not expect a significant reduction in traffic noise from the bypass. For your information, I was a noise consultant for 35 years dealing with the control of environmental noise, including the design on road noise mitigation.

Why aren’t the council planting native trees?
