Some have "lattice" towers that produce more wind speed noise. Some have poor blade design that cause them to whine. NBC carried a TELEVISION story about the high noise one one turbine that is made in Arizona, that produces about $60 to $140 per month. We RECOMMEND that you consider the source of the turbines. The turbines that www.wind-inc.us distribute make less noise than any turbines. Many people who have them have reported that they are silent, that they have never heard them. Sound tests show our turbines to produce so little noise that the microphone has difficulty picking up a reading. Most of the turbines made in Holland are of good design, are almost silent. The AVERAGE wind turbine produces less than 1/2 the noise of a typical swimming pool pump motor. Even our 250 KWH units (which can make $12,000 to $20,000+ in electricity per month) are very quiet. We interviewed a school that has 4 turbines, 50 kWh power each, on lattice towers. They said that neighbors had complained of the noise,and we personally went to see this unit. It is a loud unit, this 50 kW unit makes much more noise and is much louder than our 80 kW unit
