RESEARCH ON THE DETERMINATION OF THE NOISE LEVEL PRODUCED BY AN ATOMIZER IN DIFFERENT FUNCTIONING CONDITIONS
Noise is one of the priority issues of environment, especially in crowded urban zones. The user is more and more informed and prefers to choose some reliable products with low noise level. A low level of acoustic pollution leads to the environmental and consumer health protection satisfaction level and thus increases the quality of marketed products. 2000/14/E Directive it requires manufacturers to apply to each equipment introduced on market the guaranteed value of the acoustic power.
In this regard, the paper consists both in measuring the acoustic power level of the atomizer at maximum speed and idling. Also, in the paper will be specified choosing the method, number and place of the used microphones, calculating the average of the acustic pressure, functioning conditions, and incertitude measuring.
