This letter arrived in our mail this week. Living nearby we are happy to have the Air Force handy (unlike other newcomers) At least they are trying to stop the "I am here now, move the airbase" syndrome    |

They must be sending quite a few of these sort of things out. I have got a similar communication from the Auckland Council with regards to Ardmore. This is presumably because I own a number of South Auckland rental properties - none of which are within 5 miles of Ardmore (unfortunatly).   As I did not get a handy "protection services" plan I am not all that sure what the thing is about. The only enclosure was a FAQ sheet cunningly worded in a highly successful attempt to make the whole thing even more convuluted and obscure. What the hell is a 'rollover designation'? Am I meant to just roll over and accept it?  |

There is an interesting article here for noise abatement in the home based on being too close to the Auckland Airport ... www.aucklandairport.co.nz/~/media/Files/Community/Noise/Noise%20Treatment%20Brochure%202009.pdf Researching on Ldn40 and Ldn45 noise levels... Normal sound levels are based on the dbA scale and general noise at greater then 85dbA is considered harmful to your hearing. There is a value called Leq8 which is the 8 hr equivalent average dbA and may be 65dbA as a limit to stay under - ie an average through the working day. (L is for Logarithm, the scale to which sound in dbA is measured, ie 3dbA greater is a doibling in the sound level). They are discussing here Ldn < 45dbA which is I believe, a 24 hr average inside a house to be less than 45dbA for a Day-Night period - Ldn = average day/night period, but this does not describe peak levels which may be quite a lot higher, even inside to say 60dbA. So one really needs to talk to a specialist if they are concerned when close to the approach and departure paths. |
