The article presents a method for estimating the level of discrete white noise in an image, based on the use of linear difference operators with a vector mask. Two variants of a new method for estimating the noise level are proposed, which differ in the accuracy of the obtained estimates and computational complexity. The first version of the method can be attributed to the class of block methods, whereas the second one is intended for the rapid image analysis and is based on processing a small number of rows or columns of an image.

In the paper, a new method for accuracy noise monitoring method is presented in detail. Noise level estimation and together two vibration signals have been used to predict the noise level. The results show that the sound signal method can effectively improve the accuracy of noise monitoring, which can be very useful for further research and noise control. This method is very convenient in the testing workshop.
