![]() Yesterday with clear skies and fluffy clouds and today with almost full overcast and a gentle breeze, I can hear soaring noises almost like a street sweeping machine patrolling nearby. I can't believe it's an inversion but the only explanation I can come up with is something channeling the sound of passing airliners. They are frequently seen overhead flying south presumably from Manchester Airport. I can't say I have heard them so clearly as yesterday and today. If that's what it is. I am too far from the motorway, the nearest river is too small and there hasn't been enough rain to feed it, what else could it be? I noticed it from 07:30 till late last night and from when I woke early this morning. -- Posted via Mailgate.ORG Server - http://www.Mailgate.ORG |

This has been mentioned before in some context and it is a very good point.
The technical ones on here will know a lot more than I do. There are certain atmospheric conditions in which sound is amplified and travels miles. This is one example and sounds like a good one.

A bit mundane I know but perhaps you could have a look around your area for evidence of agricultural activity such as recently cut crops. This was a fairly common sound in one of our previous houses at this time of year in fine weather. Or are you surrounded by concrete ? Perhaps some rustic could suggest what crop is currently being harvested if any. Then again tests of a thermo-nuetrionic resonator by the Ministry of Nasty Goings On cannot be ruled out. Tom |

A bit late in the season though and nothing of that ilk in this area. When I lived in Abergele, North Wales, I was under the flight path to Manchester Airport from the west. I could tell when an aircraft was 45 degrees from me by the peak sound carried down to the ground. I often wondered if there was a reason for this as one'd expect it to be when the craft was overhead, less the distance it travelled in the time it took for the engine noise to reach us which at 5 seconds a mile would be something like half a minute. Which begged the question how the sound was heard through an inversion, for on those days when it was most noticeable, the ground based noise makers were also best heard then; traffic on the nearby motorway and etc.. -- Posted via Mailgate.ORG Server - http://www.Mailgate.ORG |

Tom We were camping last week in Yorkshire and one night a combine was going till after 11pm as the dew had not yet come down. My husband (ex-farm worker) was amazed at how far on the crops were up there compared to here in Kent -the weather has just been too dry here so nothing is ripe here yet whereas there lots of barley was being cut and the wheat was not far off iirc (I'm a city girl learning rural ways so these details might not be exact!) |

I suppose it was possible that it was a farm vehicle. They are all busy filling the roads transporting straw atm. So the timing is right. June the 21st or thereabouts is when you need to take in the hay. You want the grass head still green so that the sugar stays in the crop and unripened seed does not fall out loose. It does ripen a little in the bale. The high water content is why turning it is a necessity. If you can hear jet liners at 6 or 7 miles -under the right circumstances, it may be possible to hear a huge farm vehicle several miles away. It is quite unusual, none the less. I think wheat and other cereals can be baled immediately. The seed is allowed to fully ripen and the stalk as dry as possible. Which would put it around now, a month later, for the harvest. Do you remember the weather when the farms were all shut down due to the foot and mouth epidemic? The whole nation had good hay that year. And no livestock to eat it. You can almost picture the look on the face of the Egyptian king as he watched his chancellor's forecasts coming true, from these things. Farmers up here are going to make a few bob out of the weather the south is getting. I wonder what will go wrong next. -- Posted via Mailgate.ORG Server - http://www.Mailgate.ORG |

I could tell when an aircraft was 45 degrees from me by the peak sound carried down to the ground. Leaving aside the curvature of the earth: A liner, 5 miles up travelling at 500 miles every 3600 seconds, will be how far away when it appears to be 45 degrees from the ground? A simple isosceles triangle makes it 5 miles from overhead. At 500mph it would take 1/100th of an hour or 36 seconds. It wouldn't take that long for the noise to arrive from overhead. It will be about 7 miles away though, that's quite a distance for the sound to travel. At 5 seconds per mile where was the aircraft when it was making the most noise? -- Posted via Mailgate.ORG Server - http://www.Mailgate.ORG |
