| Abstract: | The limited Value of specific A-weighted sound level in the present standard JB/ TQh341-84 promulgated by the Ministry, which is applied to determine the unaccuracy of noise characteristics for axial-flow ventilators has been discussed. Simultaneously a measure that should be adopted to reduce the noise of high-pressure & great-flow axial flow ventilators and a limited standard value for A-weighted sound level have been also presented. This can not only keep the noise of ventilators up to A-weighted sound level, but also can decrease the noise of ventilators properly. Furthermore this can make the noise standard for axial flow ventilators be more scientific and more practicable. |
