Many serious engineers are also very small in the noise of the cooling fan, hoping to choose a cooling fan with low noise and low speed, but when he uses the same cooling fan mold, the same test conditions, different speeds, but through the software The noise value of the cooling fan obtained on the mobile phone is basically the same. What is the reason? First, the accuracy of the data tested with mobile phones is not good. Second, the environmental noise we tested might be larger than the noise of the fan. Maybe the noise tested at this time is the professional noise test equipment for environmental noise. Generally, it is a specially designed non-noise room. Most of the background noise is 21BD. The cooling fan manufacturer currently uses better equipment. The background noise is 16db. In addition, it should be mentioned that the distance between the tested product and the sensing point is It is 1m.
