• Note: Recently, a visitor reported a difficulty with the high noise point of our product We conducted experimental trying out and captured a video of the decibel meter testing the sound emitted by way of both standard speech and the maximum wind speed of a fan The check confirmed that the decibel point in the situation of human speech changed into around 70 decibels, while our product measured the maximum wind velocity of not more than 50 decibels at a distance of 30cm from the decibel meter This is a completely small sound in high-power followers
