Via Angela Kelly comes this message from acoustician Mike Stigwood, who sets out the state of play on excess AM noise from windfarms. It looks like surrender from the developers.

Recent research presented at three planning inquiries that were conducted in September, October and November (Starbold, Bryn Lleweln and Shipdham – decisions awaited)  have hopefully exposed the misconceived arguments made by the industry’s acousticians, which have successfully avoided controls over wind farm noise impact for many years.

After more than 4 years of smoke screens, obfuscation and erroneous objections raising unrealistic concerns and placing barriers in the way of necessary controls over the wind farm noise called “Excess Amplitude Modulation”, industry acousticians have finally admitted a planning condition is “necessary” and “reasonable”.  Excess AM is now shown to be neither rare nor only causing minor effects as claimed over the last few years, arguments that have successfully blocked planning controls leaving many communities exposed to serious noise impact.  Research by ourselves and the Japanese have exposed this as a common and serious problem.  Read rest of article here.
