2. Long Range Acoustic Devices (LRAD) ( http://www.lradx.com/site/content/
view/268/110 ) imported from the Advanced Technologies (USA). Two
LRAD models were evaluated; the 500× and 1,000× (largest unit available).
These devices were hand operated (see below) and were trialled across mul-
tiple days and weeks at the wind farm sites (away from turbines). The
responses of eagles and other birds to the devices were documented and
recorded.
Trials were abandoned following the 1,000× trial as there was little or no
response, from eagles on site. The 1,000× was the most powerful noise deterrent
device available at the time of the trial and technology has not advanced suffi ciently
to warrant further trial or investigation at this stage.
Further details of these programs are provided in the Annual Environmental
Performance reports for the sites ( http://www.hydro.com.au/environment/
wind-environment-program ) .
