WIND ARROW Videos & Sound
How noisy is the turbine?
Well, judge WIND ARROW for yourself. The very stiff and highly efficient carbon fiber blades are a major reason this turbine is virtually silent.
This recording was taken on a quiet but somewhat windy and sunny day. Wind is about 12-15 mph with gusts occasional gusts to 20 mph. You can hear the neighborhood dog and some kids playing a few houses away in a quiet residential setting. You can also hear the sound of trickling water coming from a sewer grate drain at the feet of the cameraman.
Which makes the most noise ... dripping water or WIND ARROW? You'll be surprised. Have a look and listen. This is unedited audio from the camera as it took this video.

NOTES ON RECORDINGS:
In order to reduce the file sizes of these recordings the video quality was sacrificed in order to focus on the best quality audio we could get. 30 Meg Quicktime .MOV videos were converted to AVI files for general access and then downsized again to WMV for fast Internet download while preserving reasonably good audio quality. As a result the blade speed is sometimes very close to the frame rate and does not appear to be turning very fast at times or even may appear to be turning backwards, when in fact they are flying at several hundred rpm. The audio recording quality however, was converted at 22.5kHz in order to preserve the most detail in all the ambient sounds as well as the sound of the turbine.
These videos are a publication of the FREE Wind Press. They may be re-printed or played for personal use only.
