Just to share a report I was reading today which may be of interest...LINKY HERE If you read the PDF at the bottom of the write up it is quite interesting.... We have a house in Penshurst we are renovating which is very close to the Macarthur wind farm and recently approved Hawkesdale wind farm. Everyone in Penshurst is whinging about the newly planned Penshurst Wind Farm, you know, the usual complaints from people who really just need something to whinge about. I might stick this in the noticeboard next time we go down there lol....insert evil laugh here! It really is wind heaven for me when we go down there, especially when we have to drive through Glenthompson for a quick view of the Oakland wind farm to get there aswell... Happy Reading...

"Electromagnetic Skull Spasms" ... ... now that's a malady I've never heard before ... LOL BS |

[quote] We have a house in Penshurst we are renovating which is very close to the Macarthur wind farm [/quote] I really hope you live in the house for several years, and then report back with your view about "Commercial Wind Farms" after a good period of time, as you too might have something to whinge about by then. The expression "Electromagnetic Skull Spasms" is a persons way of trying to explain the effects of Infra Sound, without knowing what is causing the "Skull Spasms", Its all fine to sit on the outside and scoff at those who are being effected and label them as Whingers, but just remember its not you or your health being effected. Important note..... in no way do small wind turbines emmit Infra Sound, only commercial scale mills do, so no need for alarm with small home built mills. Pete. Sometimes it just works |

[quote]AGL says that the results of the independent assessment taken at 13 neighbouring dwellings shows that the newly opened wind farm is operating “well within” the acoustic requirements of the Planning Permit – that is, the wind farm noise should not exceed the background noise level before the wind farm was operating by more than 5dB(A) or a level of 40dB(A), whichever is higher.[/quote] Yes, but the dBa scale is weighted in such a way that it closely mimics the human hearing response. Sounds outside the human hearing range can be incredibly loud but will not register as being significant on the dBa weighted scale. This includes very low frequency INFASOUND that cam make your life a total misery. There is a historical basis for acoustic measurement levels. In the 1920's and 1930's the new fangled telephone system was as big a technological step forward as the internet is today. Bell telephone labs came up with some new measurement methods to test long distance telephone networks on a firm scientific engineering basis. The Decibel, named after the Bell Telepone Lab was to be the basic measurement unit. And they measured noise on telephone lines with a frequency response weighted curve. The idea was that if you could not hear it as noise on the telephone line, it did not matter. So the dBa "A" weighting scale was derived which has historically remained the basis of all sound level measurements for almost the last hundred years. Unfortunately sound level measurements of wind farms also use this standard test method, which effectively filters out all the harmful infrasound from the measurement and gives a very false impression of the actual physical sound pressure levels present. This is not tin foil hat stuff, but engineering fact. Do your own research... Cheers, Tony. |

I'm loosing my patience with this infrasound argument. It seams every time someone posts something good about a wind farm, the poster is shot down by the anti wind farm crowd and the "infrasound will make you ill" story. Put up the science. Is it a case of infrasound, or the fear of infrasound, that's making people feel sick. I think the later, which is still a valid illness, and unlike infrasound itself, contagious. This months Silicon Chip magazine has a few letters to the editor on this topic, the one by Ted Linney sums it up nicely. But in future, I think the infrasound topic should be kept to these posts. http://www.thebackshed.com/forum/forum_posts.asp?TID=5614&PN =1&TPN=1 and especially http://www.thebackshed.com/forum/forum_posts.asp?TID=5491&PN =2 Glenn The best time to plant a tree was twenty years ago, the second best time is right now.

CLEARLY this is NOT directly or indirectly pointing the finger at ANYBODY who does actually have health issues that lives near a wind farm!!! Unless you are living 5 years from now in the Penshurst Wind Farm.... This points the finger at people who, quote "people who really just need something to whinge about". The people who complain about the white dotted lines on the road being to close together, the tree in the park that has been over pruned, the neighbours rubbish bin being to close to their fence and emitting a "slight" smell, the wind farm that is going to SPOIL THE VIEW. This needs to be re read by those who feel the need to send me insulting PM's and write rubbish posts! I did not expect to be shot down for posting something positive about a bloody wind farm. If you feel the need to PM me or ridicule me please just do one thing, READ THE BIT THAT SAYS "people who really need something to whinge about". It does not say "people who do actually have something to complain about"..... READ THE POST!!! I in NO WAY scoffed at people with health issues nor did I label them as whingers! People may have genuine issues and are not classed and I did not class them as "people who really just need something to whinge about". Read what is posted before you feel the need to reply to it! Forums are about helping each other and sharing builds etc etc, not waiting for someone to post something and then shoot them down before actually reading and understanding what was wrote. It is obviously a sensitive issue but if someone want's to share a positive post, don't put words in the posters mouth and then shoot them down for something that was not even written. Foolproof systems do not take into account the ingenuity of fools. |
