| Abstract: | This paper formulated the equation for estimating the noise of axial flow ventilators. The estimated values which were tested are tailored to the practical situation when the ventilators worked within the scope of their rated workingpoints and a part of speed adjastment. This paper also analyzed the different equations for estimating. |
