Wind turbines cause hearing loss

 
Residents living near wind turbines will be heartened by the latest research published by the Royal Society showing low frequency noise causes hearing damage interfering with the normal ear function. The wind lobby and a largely compliant medical profession has continually downplayed and ignored innumerable complaints from distressed wind farm neighbors who now have real ammunition against these ugly birdmincers.
Living close to wind farms may lead to severe hearing damage or even deafness, according to new research which warns of the possible danger posed by low frequency noise. 
The physical composition of inner ear was “drastically” altered following exposure to low frequency noise, like that emitted by wind turbines, a study has found.
The research will delight critics of wind farms, who have long complained of their detrimental effects on the health of those who live nearby.
Published today by the Royal Society in their new journal Open Science, the research was carried out by a team of scientists from the University of Munich.
It relies on a study of 21 healthy men and women aged between 18 and 28 years. After being exposed to low frequency sound, scientists detected changes in the type of sound being emitted from the inner ear of 17 out of the 21 participants.
The changes were detected in a part of the ear called the cochlear, a spiral shaped cavity which essential for hearing and balance.
“We explored a very curious phenomenon of the human ear: the faint sounds which a healthy human ear constantly emits,” said Dr Marcus Drexl, one of the authors of the report.
“These are like a very faint constant whistling that comes out of your ear as a by-product of the hearing process. We used these as an indication of how processes in the inner ear change.”
Dr Drexl and his team measured these naturally emitted sounds before and after exposure to 90 seconds of low frequency sound.

  1. Scary... I don't live near any wind turbines, but what if I live near something else that makes these low frequency sounds? Ah well, I suppose it can't be avoided so I shouldn't really worry about it. As long as I don't go deaf or something!
