AGL quells wind farm noise

ABC News, www.abc.net.au 6 March 2012

Energy company AGL says a noise defect at its Hallett Two wind farm in South Australia’s mid-north has been fixed.

After a complaint by a local resident, AGL began testing its 34 turbines at the site near Mount Bryan.

In December 2010, it identified some noise from the turbines could be heard at the nearest residence, under certain wind conditions.

A permanent acoustic treatment system was put in place late last year and recent noise testing has confirmed the issue has been resolved.

Operational constraints have been temporarily put on turbines at other AGL wind farms where audible tones have been detected.
