The top line message is that the turbine will not make enough noise to annoy your neighbours. It does operate below the background noise level at my location. This does not mean it is silent it does produce a noise that you can hear. The furthest I have heard this noise is about 90m from the turbine. It is not loud and easily drowned out any other noise but occasionally you can hear it outside. The turbine is very silent but it is distinct.

It will not be possible to hear the turbine in doors ever I am sure. I never had and none of my neighbours have complained.

The turbine is at its most noisy when the wind is blowing at full pelt but the turbine is not producing electricity. This is caused either through a sudden gust that hasn't blown long enough for the inverter to start generation or that the Grid connection is down. In these very rare situations the turbine would make more noise as it furls to shed speed, but this is very very rare.

The video of my turbine has sound and you can just hear it in that.

For my planning application I bought a cheap sound meter and recorded the background noise throughout the day and night. The council then came to check my figures and thus saved me the expense of a hiring the correct equipment and consultants.

Good luck

PS do post up your pictures as it would be great to see your location.
