Vacuum cleaners are the most likely source of noise
General household vacuum cleaners rely on vacuum to inhale small particles into the dust collection bag, the vacuum negative pressure is generated by the motor driven eddy current fan, the speed can be as high as 40000 RPM, the general motor is not up to this speed, therefore, the higher the speed, the greater the suction, the greater the natural noise ah, almost proportional. Indoor echo effect will also objectively increase the noise of vacuum cleaners, so that people feel very noisy.
Vacuum cleaner noise how to do
When it comes to vacuum cleaners, adjusting the power size can work wonders in reducing noise levels. If you're cleaning your home, it's likely that the lowest power setting is sufficient to get the job done. Using a smaller power setting will not only reduce noise, but also help save energy. It's a win-win situation!
During the vacuum cleaning process, opening a window can have a positive impact by reducing noise echo. This simple adjustment can go a long way in preventing the noise generated by the vacuum from causing too much disturbance.
3, since it is motor vibration noise, the best way is to hit a vacuum motor vibration absorber, when the natural frequency is greater than the absorber is the interference of vacuum motor vibration frequency is not a absorber vibration isolation effect, when the natural frequency of absorber and the interference of vacuum motor vibration frequency is quite not only cannot have absorber vibration isolation effect, The vibration will be amplified by the superposition of sound waves. Only when the natural frequency of the vibration absorber is less than 1.42 times of the interference vibration frequency of the vacuum motor, the vibration absorber will have the effect of vibration isolation.
