noise supress wind generator

Yep a set of THESE

The other thing you could do is treat it like a windmill and have the tail adjustable to slow the mill down, in other words angle it to the wind. The only problem with that is it will cut back on the charge rate.

The other thing you can do is put some distance between you and the generator or place some insulation between you and the generator. I got in trouble once for pushing up a bund wall between a diesel generator and living quarters so noise was kept to a minimum, 6 months later I was thanked for what I had done.

Well, welcome to the wind generator noise debate.

Lots of people are pushing wind generation as a green source of power with little or no environmental impact.

But there are plenty who raise the noise issue...seems you have the problem on a smaller scale.

Now you have not mentioned what sort of generator it is.

is it a propellor type, vertical blade type or a savernous rotor type (buckets that rotate horisontally).

anyway...there is a fundamental issue with any sort of propellor or blade running in fluid ( air or water)

At certain speeds they will be most efficient and least noisy.......if they have been designed to be efficient and quiet at low speeds they will be noiser at high speed.....if they are designed to be efficent and quiet at high speed they will be inefficient at low speed.

A high speed propellor will be fatter toward the centre and quite thin toward the ends, a lower speed propellor will be fatter toward the ends to make it more eficient at low air and rotation speed....its all to do with "tip speed ratio"..that is to do with how fast the tip of the prop is cutting the air as it rotates compared to how fast the bulk of the prop is traveling in the air that goes thru the prop.

There are some very clever things done with blade design, but the basic rule remains.

If you have a relativly cheep and cheerfull machine I doubt that the blade design will be particularly clever.

you may get some minor improvements by making sure there are no rough edges or impediments to smooth airflow over the blades...particularly at the tips........and if you where very clever and particular about keeping the rotor wellbalanced you may be able to modify the blade profile to quiet it a bit......but I recon you are stuck with what you have and the laws of physics.
