Method and system for measuring background noise of machine

摘要

A method and system for measuring noise of a machine are disclosed by the present invention, and the method includes: acquiring a first noise interference set, searching for noise interferences which are less than a preset noise interference threshold from the first noise interference set to obtain a second noise interference set, and then calculating an average value of the second noise interference set; and determining whether the average value of the second noise interference set is less than or equal to a set threshold, and if the average value of the second noise interference set is less than or equal to the set threshold, the current noise of the machine is equal to the average value of the second noise interference set. With the present invention, a more accurate measurement value of the noise of the machine can be obtained.

1. A method for measuring noise of a machine, comprising:
acquiring a first noise interference set, searching for noise interferences which are less than a preset noise interference threshold from the first noise interference set to obtain a second noise interference set, and then calculating an average value of the second noise interference set; and determining whether the average value of the second noise interference set is less than or equal to a set threshold, and if the average value of the second noise interference set is less than or equal to the set threshold, current noise of the machine is equal to the average value of the second noise interference set; and further comprising: searching for a minimum noise interference from the first noise interference set, and setting a value which is integer times of the minimum noise interference as the preset noise interference threshold.
