From Christine Bampton-Smith Since October a strange noise, low humming, vibrating and persistent has been seriously affecting a number of my ward members living around Nest Estate. From Richard Hull How typical of Calderdale that their environmental health 'experts' (hah!!) cannot identify this. Anyone with any sense can set up devices to monitor low frequency vibrations. Sounds to me like faulty electrical junctions, either on telegraph poles or in junction boxes. From H Gregg Low frequency sounds are notoriously difficult to locate. But as Richard points out - it should not be beyond the wit or imagination on the environmental health 'experts' to devise a detection method. If you try mapping those on the estate who are most affected - you can then use this as a clue to point to the possible source of the sound. The most affected will be closest to the source (possibly an electrical sub-station transformer??). Then again... it could be aliens :-) From Tharg The earthling H Gregg is using sarcasm? Let him laugh on the other side of his puny human features when I vapourise his little village. Muhahahahaha! From Chris Barnett I came across a strange and bizarre website devoted to "The Hum": not sure whether it's relevant, and it may be complete nonsense, but it's interesting...... From Christine Bampton-Smith The Enviromental Health dept are going to investigate with a machine that detects low frequency. From John Billingsley I wrote articles a few years back on various aspects of what's come to be called 'The Hum'. There's a side of it that appears to be a natural phenomenon, noted by, e.g. Gilbert White of Selborne, and some correspondents to Manchester newspapers in the late 1800s, at a time when the technological aspect of low-frequency noise was unlikely to be a factor (unless of course it's them aliens, or offcumdens as we like to call 'em here). But there's a different and very contemporary experience which seems to be related to technology, amplified by resonance in contsruction materials in modern buildings. There are various sources - a washing machine or dehumidifier for instance can set up a vibration that can be felt some distance away, often when one puts one's head on the pillow to sleep - as the bed itself becomes an amplifier. Harder to fix than to hear, of course, unless we shut everything down! My articles were in Fortean Times and Northern Earth; I don't know about FT, but the NE ones can be found here The one mentioned in the post above, deals solely with the technological aspect. From Christine Bampton-Smith A good number of people have contacted me to report they too are affected by an unidentified noise, causing headaches and sleeplessnes and pressure around the ears and jaw. I experienced the pressure when I visited affected properties although I could not hear the noise. An Enviromental Health Officer and I visited the site on Good Friday Evening with a frequency detecting machine, and although the residents could hear the noise, the machine did not pick up any very low or high frequencies. So, we are still searching for an answer. Thank you to everyone who has contacted me about this issue. From John Billingsley This inability of machines to pick up the disturbance, despite human perception of sound/resonance, is a familiar feature of the variety of infrasound, whether occurring naturally or through some presumed technological interference. From Lou R This was on the BBC website this morning - it would appear that the strange hum is also happening elsewhere ... From N Yorke
