Evaluation of Uncertainty in Measuring the Sound Power Level of Range Hoods Based on GB/T 17713-2022 Standard
This article mainly elaborates on the process of measuring the sound power level of range hoods based on the standard GB/T 17713-2022"Range hoods and other cooking smoke suction and exhaust devices".The uncertainty of measuring the sound power level of range hoods is evaluated,and the values of each uncertain component are analyzed and evaluated through the Type A and Type B evaluation methods of uncertainty.Finally,the extended uncertainty value of measuring the sound power level of this range hood is calculated.
