Method for noise reduction of silent diesel generator set

A silent diesel generator set, as its name suggests, is a diesel generator that emits less noise. It is used in places that require diesel generators to supply power and do not want to receive noise interference, such as schools, hospitals, cinemas, banks, hotels or special meeting places. In order to meet the environmental protection and special requirements of users, generator set products urgently need noise reduction technology. How to achieve better noise reduction effect for diesel generator sets?

 

The silent diesel generator set supplied by JUNVOCH is an additional silent box on the basis of the diesel generator set. The volume of the box can be customized according to the volume of the diesel generator set. The box board of the silent box of the diesel generator set is finely made, and the thickness can reach between 1.5mm-2mm, which has high damage resistance. The diffused form design of the range absorption sound wave, the sound barrier transmission is relieved through the bubbles one by one, and the wave peak absorbs. We know that the diffusion of sound waves spreads in a curved shape. The sound-absorbing cotton inside the mute box is completely based on the surface area of ​​the sound cotton, which is more than 4 times the plane area. .

 

During the normal use of the silent diesel generator set, the sound that the outside world can hear can only reach 65-68 decibels.
