Then analytical measurements of the noise were carried out on both of the turbines by means of modern acoustic apparatus and a conclusion has been found that the noise of the concentrated wind energy turbine is lower than the one of the ordinary wind energy turbine and the root of the trouble to cause noise chiefly originates from the turbine blade. besides, the result of analytical measurement also reveals that the power output both of the wind energy turbines will increase with the increase of the wind speed and unfortunately does the noise too. in order to lower the noise, a measures of noise reduction have been advanced that an active method is to develop a wind energy turbine run at a lower rating of wind speed while the passive method is to adopt a board drilled tiny holes, having established a sound technological basis for the development of a kind of wind energy turbine of low noise and high level in the world
