The noise measuring of electric motors is already well known and understandable, but when the motor producer wants to measure the motor noise directly on the motor assembly line (as out-going inspection) then come several troubles which must be fixed. The most important is to eliminate the background noise – the sound pressure on the work shop can be over 80 dB somewhere so then is practically impossible to do a motor noise measuring. It is necessary to use a noise-box to reduce the background noise – see Fig.2. Next trouble can be the test results evaluation - especially in case of special "noise requirements" with strict acceptance criteria. Here we have to count also with additional disturbances caused for example by using of bearings from different manufacturers.
